TIG welding machine welding machine welding firmly or cold welding machine welding

TIG welding is firm.

Because TIG welding is arc welding.

It is melt welding, with a cold welding machine.

One of the biggest differences 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. Current density.

Large, heat concentration, high deposition rate, fast welding speed.

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.

Argon arc welding mainly welds thick plates, which itself belongs to hot welding, the solder joints are diffused outward, and the welded thin plate is easy to deform and change color, and the cold welding machine is used in the thin plate, which is to release the electric energy stored in the capacitor in the form of a pulse arc between the tungsten electrode and the workpiece in an instant, and the extremely high temperature arc makes the workpiece and welding wire composed of metal materials quickly melt and weld together, so as to achieve the purpose of welding repair. This method of welding repair is characterized by a very short time and very little calorific value.

It is undeniable that the strength and penetration depth of argon arc welding are better than that of cold welding machines, but argon arc welding belongs to hot welding, with large deformation and large color difference after welding, suitable for products with low requirements.

Hello, dear, happy to answer your <>

A: Cold welding and electric welding, electric welding is stronger. Cold welding machine and electric welding machine welding, of course, electric welding machine welding is more sturdy.

The cold welding machine is generally spot welded, and the penetration depth of the welding is relatively shallow, that is, the surface of the weld is welded. The arc welding machine is not the same, the spot welding machine can be arc welding, and its welding penetration can be relatively deep. Therefore, the firmness of its weld is not comparable to the surface weld of the cold welding machine.

So the weld of the arc welding machine is stronger.

Summary. Hello dear, <>

Why is the stainless iron welding not firm with argon arc welding, and the iron welding iron can't be welded? This is really the first time I've heard of argon arc welding iron, and in general, argon arc welding iron is very good. TIG welding is mainly used to weld iron and stainless steel.

If you can't weld the iron, then it must be that the current you are welding is too small. The accuracy of TIG welding is relatively high, and it can be welded with a small current. At this time, you need to increase the current a little bit to be able to weld.

Hello search good dear, <>

Why is argon arc welding welded stainless iron welding not firm, argon arc welding welding iron welding is not erected socks? This is really the first time I've heard of argon arc welding iron, and in general, argon arc welding iron is very good. TIG welding is mainly used to weld iron and stainless steel.

If you can't weld the iron, then it must be that the current you are welding is too small. The residual accuracy of TIG welding is relatively high, and it can be welded with a small current. At this time, you need to increase the current a little bit to be able to weld.

The reason why argon arc welding does not destroy the balance chain may be that the current is too small and the iron cannot be melted. Or the angle of the welding torch is not suitable, or it may be that the wrong welding consumables are used to cause the welding to not be blocked.

If the operation reason is excluded from the welding, 1, argon purity 2, the machine parameters are not adjusted correctly, such as the size of the welding current, the size of the arc and the hand arc current 3, the size of the groove design and the welding is not transparent, it will also affect the welding quality of the molding is not good 4, the gas information protection is not in place, and some need to do double-sided protection, such as the pipeline docking that needs to be detected by the world, the need to slip the gas protection on the back, or the protective agent of the back protector We-60F.

Hello, I am a teacher from Xiaoli, and I have provided consulting services to nearly 4,000 people, with a cumulative service time of more than 1,000 hours! I've seen your question, and I'm sorting out the answer now, it will take about three minutes, so please wait a little bit Thank you

2. The difference in the amount of deformation: the thin plate is not easy to deform when welded. The welding temperature is much lower than that of the argon arc welding machine, and the cold welding machine has a great advantage over the argon arc welding machine in thin plate welding, the deformation of thin plate welding is very small, and the thinnest plate can be achieved by manual welding, and the high-quality welding of the plate can be achieved by manual welding, compared with the tungsten argon arc welding machine, the cold welding machine is not easy to burn through.

Disadvantages of TIG welding:

1.The requirements for the use of the welder master are high, and the welder master can only be used maturely in 3-5 years, and the cost of the factory is relatively high.

2.The impact on the workpiece is large, and it is easy to have secondary defects such as deformation, discoloration, porosity, undercut, edge cracking, and collapse.

ZD3K-100 cold welding machine.

Features: Small heating, easy to operate, all kinds of metal welding repair, no secondary defects (deformation, porosity, undercut, cracks).

High-frequency discharge, so that the welding wire and the workpiece are in a metallurgical bonding state, and the bonding degree is high.

Every equipment will exist only if there is a market demand, and the same is true for cold welding machines and argon welding machines; In the thin plate welding and welding repair industry, market demand determines which welding machine to choose;

1. Argon arc welding.

1. TIG welding can only weld the above welding wires, and the accuracy of welding repair is not high;

2. The temperature of argon arc welding is relatively high, and it is easy to change color and deform;

3. The welding scar of argon arc welding is large, and the damage to the mold is relatively large;

4. After argon arc welding and repairing the mold, it generally cannot be processed on the machine tool, so it can only be processed manually, such as file frustration, oil and oil, and welding scars.

It's a waste of time when you're big;

5. Heat treatment is required after argon arc welding, otherwise the service life of the product will be affected.

2. Cold welding machine.

1. The cold welding machine has achieved the welding and welding repair accuracy of laser welding;

2. The cold welding machine can accurately set the output current and welding repair time, and will not change color or deform;

3. The welding scar of the cold welding machine is small, and the damage to the mold is small;

4. After the cold welding machine is repaired, it can be processed on the machine tool;

5. There is no need for heat treatment after the cold welding machine, which will not affect the service life of the product.

The difference between cold welding machine and argon welding machine is that the heat of cold welding machine is relatively small compared to argon arc during the welding process, the instantaneous output time is short, the efficiency is relatively low, but the deformation is small.

The biggest difference between them is the difference in role and characteristics.

A process (method) that applies mechanical, molecular or electric force to diffuse welding consumables to the surface of the appliance. It is often used to repair out-of-tolerance, coatings. A negative effect that must be considered in physics at the nanometer size.

Among them, the first two are used to repair small defects such as wear, scratches, porosity, and sand holes on the surface of metals and castings; The latter is used for welding non-ferrous metal wires such as copper wires and aluminum wires, such as the welding of engine enameled wires.

Hardfacing type: Using the charging capacitor, it is discharged in an ultra-short time of 10 -3 10 -1 seconds cycle, 10 -6 10 -5 seconds. Due to the alloying between the base metal and the base metal, it spreads to the inside of the workpiece, melts and infiltrates, forms a diffusion layer, and obtains a high-strength bond.

The principle of achieving the advantages and disadvantages of the cold weld bush (low heat input) is that the discharge time (pt) is extremely short compared to the next discharge interval (IT), and the machine has enough relative stopping time that the heat will be diffused to the outside world through the mold primitive.

Therefore, there is no accumulation of heat in the machined part of the mold. It can be divided into pliers, long handles, tabletops, hydraulic cold welding machines, etc. It is of great significance for repairing old equipment and reducing waste and defects in the manufacturing process.
