How to adjust the welding machine for welding aluminum formwork? How to set up the argon arc welding

Welding aluminum template with double pulse gas shielded welding machine, adjust the current, you can open the molten pool as the standard, and then the rest is to operate, and the welding process can be adjusted according to the size of the welding spatter to adjust the correction voltage.

The adjustment of the welding aluminum template welding machine mainly includes the following aspects: welding current, welding time, welding speed and welding pressure.

First of all, the adjustment of the welding current is very important. The size of the welding current directly affects the quality and effect of welding. Generally speaking, when welding aluminum formwork, the welding current should be moderate, too large will cause the welding to overheat, too small can not achieve the welding effect.

Therefore, when adjusting the welding current, it is necessary to determine the appropriate current size according to the specific welding requirements and the thickness of the aluminum template.

Secondly, the adjustment of the welding time is also very important. The length of welding time directly affects the firmness of the weld. Generally speaking, the welding time should be moderate, too long will cause the welding to overheat, too short will not achieve the welding effect.

Therefore, when adjusting the welding time, it is necessary to determine the appropriate welding time according to the specific welding requirements and the thickness of the aluminum formwork.

In addition, the adjustment of the welding speed is also very important. The speed of welding directly affects the quality and efficiency of welding. In general, the welding speed should be moderate, too fast will cause the weld to be not strong, and too slow will cause the weld to overheat.

Therefore, when adjusting the welding speed, it is necessary to determine the appropriate welding speed according to the specific welding requirements and the thickness of the aluminum formwork.

Finally, the adjustment of the welding pressure is also very important. The magnitude of the welding pressure directly affects the firmness of the weld. Generally speaking, the welding pressure should be moderate, too large will cause the welding to overheat, too small will not achieve the welding effect.

Therefore, when adjusting the welding pressure, it is necessary to determine the appropriate welding pressure according to the specific welding requirements and the thickness of the aluminum formwork.

In a word, the adjustment of the welding machine for aluminum formwork needs to determine the appropriate welding current, welding time, welding speed and welding pressure according to the specific welding requirements and the thickness of the aluminum template. Only by adjusting the appropriate parameters can the quality and effect of welding be guaranteed.

Welding aluminum to use square wave AC, the setting is more, generally to adjust the cleaning width and AC frequency, tungsten rod should be used pure tungsten when welding, will be in the front end of the tungsten rod into a round ball during welding, so that it has a good effect on cleaning the welding surface.

The welding port is much simpler to weld stainless steel, using DC output, directly adjust the current size, tungsten rod is generally made of thorium tungsten or cerium tungsten, and the tungsten rod should be sharpened during welding, so that the arc will not be concentrated.

On the basis of the principle of ordinary arc welding, the protection of argon on metal welding consumables is used, and the welding consumables are melted into a liquid state on the welded substrate to form a molten pool through high current, so that the welded metal and the welding consumables can achieve metallurgical combination.

Non-melting electrode argon arc welding is the arc between the non-melting electrode (usually tungsten electrode) and the workpiece, and a kind of inert gas (argon gas commonly used) that does not react with the metal flows around the welding arc to form a protective gas hood, so that the tungsten terminal, the arc and the melt pool and the high-temperature metal adjacent to the heat-affected zone are not in contact with the air, which can prevent oxidation and absorb harmful gases. The result is a dense welded joint with very good mechanical properties.

The welder starts arc welding at the outer groove, and the stainless steel lining ring with a higher melting point temperature forces the inner penetrating weld to be formed intact to ensure that the surface of the weld is formed.

Adjustment of TIG welding pulse parameters.

1. Turn the DC and pulse transfer switch to pulse. This switch is used to convert the output of the welding machine to DC or pulse, when this switch is in DC, the output of the welding machine is DC, and vice versa, and it must be placed in the DC state when manually welding.

2. "Base Current" adjustment knob: This knob works in the pulse state. It is used to adjust the amount of arc current maintained during pulse welding.

3. "Pulse frequency" adjustment knob: This knob only works in the pulse state, and is used to adjust the number of times the pulse welding current occurs (fast or slow) The higher the pulse frequency, the denser the welding ripples, and vice versa, the thinner.

4. "Pulse width" (duty cycle): This knob only works in the pulse state. It is used to adjust the duration of the pulse welding current, the wider the pulse width, the wider the weld seam is relatively wide and deeper, and vice versa, it is narrow and shallow.

TIG welding pulse] is a method of welding by supplying a pulse current that changes according to a certain law to the arc from the welding power source. The welding process is to maintain the stable combustion of the arc by the basic current, and the melted parts are heated with a controllable pulse current, each pulse forms a point-shaped molten pool, and the pulse gap molten pool is solidified into a solder joint, and when the next pulse current acts, there are some filler metals and base metal metals on the partially solidified solder joints to be melted to form a new molten pool, and through the adjustment of the welding speed and pulse gap, the solder joints that overlap each other are obtained, and finally the continuous weld is obtained.

Dear, hello, I am glad to answer for you: how to debug the aluminum welding machine welding aluminum WSE-315 argon welding machine welding aluminum welding machine welding aluminum key adjustment control panel AC function, argon arc welding, pulse no can, and then adjust the current size according to the thickness of the plate when welding. Welding aluminum first has to hit the AC file to lift the lead, and then the current adjustment knob is to decide whether to adjust the size or size according to the thickness of the plate, and then if you want to pulse, you can adjust the pulse knob, and other knobs can not be used.

2. 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 aluminum alloy material, with high strength and light weight. The main welding processes are manual MIG welding (MIG welding) and automatic MIG welding, with its base metal, welding wire, shielding gas, and welding equipment. Thank you for your patience.

The above is all my reply, if you are satisfied with my service, please give a thumbs up, and I wish you all the best again! Peace and joy!

Answering the kiss, aluminum and aluminum alloy materials, through heating or pressure to melt to achieve the effect of combination, in the fusion process can be used welding wire or metal filling, can also use two workpieces self-melting, so that the molecules at the fusion of the two workpieces penetrate each other to form a permanent connection of the process equipment. 2. The use of low voltage and high current electric energy, the electric energy through the arc instantly converted into heat energy, the use of high-purity argon gas as the shielding gas during welding, to avoid the generation of pores, impurities during welding, at the same time, AC argon arc welding and MIG gas shielded welding have a certain cathodic cleaning function, can directly remove aluminum and aluminum alloy oxide film. Because the aluminum welding machine is small in size, simple in operation, easy to use, high in welding efficiency, good in weld forming, large in penetration, it can weld through aluminum and aluminum alloy plates to achieve high-quality bonding effect, and the welding strength is the same as that of the base metal, and the sealing is good, so it is widely used in various fields of industry and life.

Aluminum welding machine will produce arc light in the process of use, arc light contains infrared, ultraviolet rays, but also produces metal vapor and smoke and other harmful substances, tungsten rod in tungsten argon arc welding contains a small amount of radioactive elements, so must do enough protective measures, in addition, because of the use of argon as a protective gas, should not be operated in the windy welding field.

Summary. The following steps are required to debug the aluminum welding machine to weld aluminum:1

Preparation: Clean the aluminum parts, cut them into the desired shape, and prepare the welding wires, pliers, etc. needed to weld the aluminum. 2.

Adjust the current parameters: The conductivity of aluminum is poor, so you need to turn the current down, generally between 100-150A. The current can also be adjusted according to the size and thickness of the weldment.

At the same time, the current should not be too large so as not to burn out the wire and wire. 3.Adjust the electrode spacing:

Start by making sure the electrodes are spaced correctly. It is usually recommended that between 1mm-2mm, the distance from the electrode to the copper tip should not be too close or too far, too close will be prone to short circuit, too far will be prone to arc instability, poor welding effect problems. 4.

The following steps are required to debug the aluminum welding machine to weld aluminum:1Preparation:

Clean the aluminum, cut it into the desired shape, and prepare it to regrip the wires, pliers, etc. needed to mimic the aluminum. 2.Adjust the current parameters:

The conductivity of aluminum is poor, so the current needs to be turned down a bit, generally between 100-150A. The current can also be adjusted according to the size and thickness of the leakage fiber of the weldment. At the same time, the current should not be too large so as not to burn out the wire and wire.

3.Adjust the electrode spacing: First, make sure that the electrodes are spaced correctly.

It is usually recommended that between 1mm-2mm, the distance from the electrode to the copper tip should not be too close or too far, too close will be prone to short circuit, too far will be easy to produce arc instability, poor welding effect. 4.Adjust the welding time:

Choose the appropriate welding time to ensure the welding quality. If the time is too long, it will be overheated, and if the time is too short, it will lead to poor welding quality.

After the welding is completed, check the welding quality, if there is any defective phenomenon, you need to adjust the corresponding welding parameters. It should be noted that when welding aluminum in the aluminum welding machine, the thermal conductivity of aluminum is good, so it is necessary to pay attention to the temperature of aluminum parts at all times to avoid overheating and deformation. In addition, it is also necessary to use pure aluminum welded bridge wires to avoid the contamination of miscellaneous grip quality and cause aluminum welding not to be firm.

What kind of gas is used, and whether it works in DC or AC.

For aluminum welding machines to weld aluminum materials, the AC working method is usually adopted. This is because aluminum is a material that is easily oxidized, and direct current will accelerate the thickening of the oxide film on the surface of aluminum, resulting in poor welding results. In terms of gases, argon is usually used as a shielding gas.

The use of argon as a shielding gas prevents oxidation and contamination of the aluminum by oxygen and nitrogen in the atmosphere, and maintains the stability and consistency of the welding process. In the specific debugging of welding parameters, it is necessary to determine the appropriate welding current, voltage, welding speed and argon flow rate and other parameters according to the thickness and model of the aluminum to achieve the best welding effect. It is recommended to record and refer to the experimental data to ensure that the parameters obtained from the debugging are suitable for different scenarios in the actual aluminum welding work.
