Masters who understand argon arc welding machine, please enter, how to use argon arc welding machine

AC TIG Welding Characteristics Independent Amplitude Current control can be adjusted to set the positive and negative half-wave current values of AC independently, so as to accurately control the heat input of the workpiece and electrode. Balance ratio control, which allows for the adjustment of the oxide removal function, is the basis for high-quality welding of aluminum. These models expand the range of applications.

Frequency adjustment can control the width of the arc cone, which can improve the control of arc direction. AC waveform advanced square wave melt pool fast solidification, deep penetration and fast welding speed. The gentle arc of the soft square wave allows for maximum control of the melt pool and good wetting.

Sine wave is suitable for users who prefer traditional arcing, quiet welding and good wetting effect. The triangle wave reduces the heat input, which is especially suitable for the welding of thin aluminum plates, and the welding speed is relatively fast. The DC TIG welding characteristics are very smooth and accurate....

WS means Non-Melting Pole Hand Arc Welding Machine.

TIG also means non-melting pole hand arc welding machine.

There are two main types of welding machines.

Welding of the melting electrode and welding of the non-melting electrode.

The two brands you mentioned above are all at the same level You can buy it if you do small work or don't use it often, if you want to use it often, it is not recommended, you should buy an IGBT welding machine.

I haven't heard of the two brands, and I don't judge them well. WS and TIG are just different in terms of expression. There is no difference. It's all the same thing.

You're talking about Tongtian Bo welding.

I know all the way.

But I used it by Nike.

Or Jasic from Shenzhen.

That's what you're asking. Carbon dioxide is argon shielded welded.

What kind of welding machine, right?

The price depends on what you're up for.

My argon arc is 8000+.

CO2 is 15000+.

The main thing is the brand and the use.

I don't know these two brands very well, and it's hard to talk about them.

1. The argon arc welding must be operated by a special person.

2. Check whether the equipment and tools are in good condition before work.

3. Check whether the welding power supply, the control system has a grounding wire, and the transmission part is lubricated. The rotation should be normal, and the argon and water sources must be unblocked. If there is any water leakage, it should be repaired immediately.

4. Check whether the welding torch is normal and whether the ground wire is reliable.

5. Check whether the high-frequency arc striking system and welding system are normal, whether the wire and cable joints are reliable, and check whether the adjustment mechanism and wire feeding mechanism are in good condition for automatic wire argon arc welding.

6. Select the polarity according to the material of the workpiece, connect the welding circuit, use DC positive connection for general materials, and reverse connection or AC power supply for aluminum and aluminum alloy.

7. Check whether the welding groove is qualified, there shall be no oil stain and rust on the surface of the groove, and the oil and rust should be removed within 200mm on both sides of the weld.

8. Check the reliability of the fetal tool, and check the preheating equipment and temperature measuring instrument if the weldment needs to be preheated.

9. The argon arc welding operation button should not be far away from the arc, so that it can be closed at any time in the event of a failure.

10. When using high-frequency arc striking, it is necessary to check whether there is leakage.

11. If the equipment fails, the power should be cut off for maintenance, and the operator shall not repair it by himself.

12. It is not allowed to be naked and naked in other parts near the arc, and it is not allowed to smoke or eat near the arc, so as to avoid ozone and smoke inhalation into the body.

13. When grinding thorium tungsten electrode, you must wear masks and gloves, and abide by the operating procedures of the grinder. It is best to use cerium tungsten electrode (the radiation dose is smaller). The grinder must be equipped with an exhaust device.

14. Operators should wear electrostatic dust masks at all times. Minimize the time of high-frequency electrical action during operation. Continuous work shall not exceed 6 hours.

15. The argon arc welding work site must be well ventilated. Ventilation and detoxification equipment should be started during work. When the ventilation device fails, it should stop working.

16. Argon cylinders are not allowed to be smashed, and there must be a bracket for vertical placement, and they are more than 3 meters away from open flames.

17. When argon arc welding is carried out inside the container, a special mask should be worn to reduce the inhalation of harmful smoke. There should be a person outside the container to supervise and cooperate.

18. Thorium tungsten rods should be stored in a lead box to avoid injury due to the radioactive dose exceeding the safety regulations when a large number of thorium tungsten rods are concentrated together.

Cleaning width: It is to adjust the positive and negative width of the square wave output, the smaller the value, the more positive the output of the welding gun, the narrower the weld bead, the deeper the molten pool, the greater the loss of tungsten electrode (easy to burn tungsten electrode); The higher the value, the more negative the torch output, the wider the weld bead, the shallower the weld pool, and the smaller the tungsten electrode loss.

The thyristor argon arc welding machine generally uses a controlled square wave to control the output of the welding machine, and its output is also a square wave.

The argon arc welding machine is a machine that uses argon arc welding, which adopts the arc starting method of high-pressure breakdown. Argon arc welding is tungsten inert gas arc welding, which refers to the welding method of using industrial tungsten or active tungsten as a non-melting electrode and inert gas (argon) as protection, referred to as TIG.

Generally, it is used for 6 lomm thin plate welding and thick plate single-sided welding and double-sided bottom welding. Commonly used welding machines are domestic YC-150 manual tungsten argon arc welding machine.

Non-melting pole TIG welding.

Non-melting electrode argon arc welding is the arc between the non-melting electrode (usually tungsten electrode) and the workpiece burning, around the welding arc flows through an inert gas that does not react with the metal (argon is commonly used), forming a protective gas hood, so that the tungsten terminal head, arc and molten pool and the metal that has been at high temperature do not contact with the air, can prevent oxidation and absorb harmful gases. The result is a dense welded joint with very good mechanical properties.

Melting pole argon arc welding.

The welding wire is fed through the wire wheel, and the contact tip conducts electricity, which generates an arc between the base metal and the welding wire, melts the welding wire and the base metal, and uses inert gas argon to protect the arc and molten metal for welding.

The difference between it and tungsten argon arc welding: one is that the welding wire is used as an electrode, and is continuously melted and filled into the molten pool, and the weld is formed after condensation; The other is the use of shielding gas, with the application of melting pole argon arc welding technology, shielding gas has developed from a single argon gas to a variety of mixed gases are widely used, such as AR 80% + CO220% argon-rich shielding gas.

Usually the former is called MIG and the latter is called MAG. From the perspective of its operation mode, the most widely used is semi-automatic melting pole argon arc welding and argon-rich mixed gas shielded welding, followed by automatic melting pole argon arc welding.

Argon arc welding has water cooling and air cooling, generally high-power argon arc welding will use water cooling, because the welding gun, wire conduction current is larger and the heat generated will also increase, too high heat will lead to hot welding torch and part of the welding machine damage, so the high-power argon arc welding machine will use water cooling cooling, water-cooled argon arc welding machine is generally used in the production of large equipment.

At present, most of the common argon arc welding machines are air-cooled, the welding power is small, the calorific value is not high, the welding gun and the wire will be naturally cooled in the air, and the argon gas flowing in the welding gun will also take away part of the heat of the welding gun and the wire, so it is used in small and medium-sized weldments and the work of continuous welding time is not very long.

Above 250a are generally water-cooled guns, because air-cooled guns are too expensive.

Dizzy, when did it happen, the last century, now it's all built-in water tanks, and it's also water cooling, and that's what I'm using now.

Tungsten argon arc welding is the welding of argon as a shielding gas. With the help of an electric arc created between the tungsten electrode and the weld body, the welding material itself (which is also melted when filler metal is added) is heated and melted, and then the weld metal is formed. Tungsten electrodes, molten pools, arcs, and areas of joints heated by arcs are protected from atmospheric contamination by argon gas streams.

During TIG welding, the relative positions of the torch, filler metal and weldment are as follows:

The arc length is generally times the diameter of the tungsten electrode.

When welding is stopped, the filler metal is first withdrawn from the weld pool (the filler metal is added according to the thickness of the weldment), and the hot end remains under the protection of the argon gas flow to prevent oxidation.

1.Welding torch (torch).

In addition to clamping the tungsten electrode and delivering the welding current, the tungsten argon arc welding torch (also known as the welding torch) also sprays a shielding gas. High-current welding torches are also required to use water-cooled welding torches for long-term welding. Therefore, it is very important to use and protect the welding torch correctly.

Tungsten electrode load current capacity (a).

Tungsten electrode diameter (mm): pure tungsten, thorium tungsten, cerium tungsten.

2.Gas path. The gas route is composed of argon cylinder pressure reducing valve, flow meter, hose and solenoid valve (in the welding machine). Pressure reducing valves are used to reduce pressure and regulate the pressure of shielding gases. The flowmeter is to calibrate and adjust the flow rate of shielding gas, and the argon arc welding machine usually adopts a combined and integrated pressure reducing flowmeter, which is convenient and reliable to use.

3.Argon purity.

The requirements of argon purity of the material during argon arc welding.

The metal material chromium-nickel stainless steel is too refractory metal.

Argon purity.

4.Specification parameters.

The specification parameters of tungsten argon arc welding are mainly composed of current, voltage, welding speed and argon flow, and their values are related to the type of material to be welded, plate thickness and joint type. Other parameters such as the length of the tungsten electrode extending from the nozzle are generally 1-2 times the diameter of the tungsten electrode, the distance between the tungsten electrode and the weldment (arc length) is generally taken below the diameter of the tungsten electrode, and the size of the nozzle is selected after the welding current value is determined. The general specifications of stainless steel argon arc welding are as follows:

Current type and polarity Plate thickness Welding current (a) Argon flow rate (l min) Wire diameter.

DC forward 30-50 4

Weld surface color and gas shielding effect.

The weldment material is best, good, good, bad, worst.

Stainless steel, silvery, golden, blue, red-gray, gray, black, titanium, bright silver-white, orange-yellow, blue-violet, blue-gray, white titanium oxide powder.

6.Clean up before welding.

Tungsten TIG welding is quite sensitive to the contamination of the surface of the weldment and filler metal, so the grease, coating, lubricant and oxide film on the surface of the weldment must be removed before welding.

TIG welding is firm.

Because argon arc welding is arc welding, it is melt welding, and one of the biggest differences with the cold welding machine is that when welding, the temperature of the workpiece is relatively high, which will cause the annealing of the welded workpiece and cause the workpiece to deform. The current density is large, the heat is concentrated, the deposition rate is high, and the welding speed is fast.

1.TIG welding machine product features:

1) Adopt advanced inverter technology, high working frequency, small size, light weight and easy to carry.

2) Adopt high-frequency pressurized arc striking and pulsed thermal arc striking technology, excellent arc initiation performance, sufficient welding current, and excellent performance ratio.

3) Unique output characteristics design, more suitable for wire filling welding, beautiful weld.

4) Wide working range, strong network adaptability, high load sustainability rate, more suitable for continuous operation of the factory.

5) It is suitable for welding of stainless steel, carbon steel, copper and other metals.

2.Cold welding machine features:

1) Reasonable design and free adjustment. Different discharge frequencies can be selected according to different metal materials to achieve the best repair effect.

2) Small heat-affected area. There is no heat input during the instantaneous process of stacking, so there is no deformation, undercut and residual stress. No local annealing occurs and no re-heat treatment is required after repair.

3) Extremely small welding impact, this welding machine overcomes the phenomenon of impact on the workpiece by ordinary argon arc welding in the welding repair process. It is also possible to repair the machining surface of the workpiece with no margin.

4) High repair precision: the thickness of surfacing is from a few microns to a few millimeters, only grinding and polishing.

If you solder things when the mind is calm in a few days can be learned, the key is the problem of technology and hand, as long as you do it regularly, the manual will be good!

It's not difficult, it's not difficult, the main thing is how much you put your heart on a profession, how much effort you put into it, and you have to learn from a master with a high hand, and you have to learn from their experience, and at the same time, it feels very important.

One month is enough, the key is your actual operation time, the master can tell you the method, but the specific time is up to you to do, so not only to be diligent, but also to account skills.

1. The welding machine you mentioned is called manual welding and argon arc welding.

2. DC and pulse selection are generally for argon arc welding.

3. Manual welding (electrode arc welding) is the welding form of welding rod plus electrode, which is what you call "the kind of welding electrode clamping", with the corresponding material (number) of the electrode, generally used for welding between steel, iron and stainless steel workpieces with a thickness greater than 2 mm, compared with argon arc welding, it has the advantages of simple operation and high work efficiency, but there are shortcomings such as welding slag particle spatter, easy slag inclusion in the weld and large and unbeautiful weld.

4. Argon arc welding is a welding form of argon arc welding gun and corresponding material (number) welding wire, the argon protection during welding can isolate the adverse effects of oxygen in the air on the welding area, and the arc combustion is stable, the heat is concentrated, there is no spatter, the weld is dense, the forming is beautiful, the workpiece deformation and crack tendency are small, in addition to steel, iron, stainless steel, it can also weld more active metals and alloys such as magnesium, titanium, aluminum, etc.; But it should be equipped with argon (generally high-pressure gas cylinders) and argon pressure reducing device, the thickness of the workpiece for a welding is not as large as manual welding, generally suitable for millimeter thickness, and the welding technology is more difficult to master than manual welding.

5. Pulse argon arc welding is easy to control the welding temperature heat input, which can not only weld through but also not easy to weld through, especially suitable for the welding of thin-walled (millimeter) workpieces, and easy to form a beautiful fish scale weld.

6. TIG welding is currently widely used in stainless steel welding.

7. Argon arc welding is also applied to the bottom welding of thick-walled workpieces, that is, after the bevel of the workpiece is aligned, the argon arc welding is used to weld at the bottom, and then the manual welding (cover surface) is used on it, so that the weld can be of higher quality and smaller thermal deformation than ordinary manual welding.

The above are the simple knowledge and skin of manual electrode arc welding and argon arc welding, more in-depth and detailed related knowledge, and hope to consult more professional related information. Hope it helps!
