Which TIG welding master can tell me the method of welding aluminum, thank you

Summary. OK. TIG welding can weld almost all metals, especially some refractory metals, easily oxidizing metals, such as magnesium, titanium, molybdenum, zirconium, aluminum, etc. and their alloys.

TIG welding is mainly used in the welding of aluminum and aluminum alloys, copper and copper alloys, magnesium and magnesium alloys, titanium and titanium alloys, high-temperature alloys, etc., and has a wide range of applications in many important industrial sectors.

The working principle of argon arc welding is the same as that of hand arc welding in the main circuit, auxiliary power supply, driving circuit, protection circuit, etc. In addition to the same electric shock, burns, and fire as electrode arc welding, argon arc welding also has high-frequency electromagnetic fields, electric shock radioactivity, and arc light damage that is much stronger than that of arc welding.

Extended information: TIG welding is divided into two types: MIGG welding and non-MIG welding according to the different electrodes.

1. Non-melting electrode: non-melting electrode argon arc welding is the arc is burned between the non-melting electrode (usually tungsten electrode) and the workpiece, and an inert gas (argon gas commonly used) that does not react with the metal flows around the welding arc to form a protective gas cover, so that the tungsten terminal, the arc and the molten 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.

2. Melting electrode: 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, so that the welding wire and the base metal are melted, and the inert gas argon is used to protect the arc and molten metal for welding.

Can I weld the aluminum plate TIG welding?

Because the Amengli aluminum argon arc welding machine belongs to AC argon clear arc welding, the output is AC output, and the output is through the AC square wave transmission. Why does argon arc welding know the thickness of aluminum plate to crack?

The wires are not welded together.

Additional Information:

According to the different electrodes, TIG welding can be divided into two types: MIG welding and non-MIG welding. 1. Non-melting electrode: non-melting electrode argon arc welding is the arc is burned between the non-melting electrode (usually tungsten electrode) and the workpiece, and an inert gas (argon gas is 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 molten 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.

As a result, a welded joint before dense lifting is formed, and its mechanical properties are very good. 2. Melting electrode: The welding wire is fed through the wire base cleaning 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.

TIG welding can weld aluminum, and argon arc welding can weld stainless steel, high-temperature alloys, titanium alloys, aluminum alloys and other materials, which are used in nuclear energy, aerospace, shipbuilding, electronics, metallurgy and other industries.

Aluminum alloy welding method:

1. Tungsten argon arc welding.

Tungsten argon arc welding is mainly used for aluminum alloy and is a good welding method, but tungsten argon arc welding equipment is more complex and not suitable for operation in open air conditions.

2. Resistance spot welding and seam welding.

This welding method can be used to weld aluminum alloy sheets with a thickness of less than 5mm. However, the equipment used in welding is more complex, the welding current is large, and the productivity is high, which is especially suitable for mass production of parts and components.

3. Pulse argon arc welding.

Pulsed argon arc welding can improve the stability of the welding process, and the parameters can be adjusted to control the arc power and weld forming. The weldment has small deformation and small heat-affected zone, which is especially suitable for thin plate, all-position welding and other occasions, as well as the welding of forged aluminum, duralumin, and ultra-duralumin with strong heat sensitivity.

4. Friction stir welding.

Friction stir welding is first and mainly used in the field of light metal structures such as aluminum alloy and magnesium alloy, and the biggest feature of this method is that the welding temperature is lower than the melting point of the material, which can avoid defects such as cracks and porosity caused by fusion welding.

DC argon arc welding machine can not weld aluminum, to use AC and DC argon arc welding machine, to weld aluminum to use AC, if you need a beautiful weld bead to use AC and DC argon arc welding machine with pulse, welding thin plate does not need to fill aluminum wire, thick plate needs to fill aluminum wire.

You need AC and DC pulse argon arc welding machine to weld aluminum, DC is to weld stainless steel, AC is to weld aluminum, nothing else is needed, of course, you have to buy aluminum welding wire.

If argon is used, the conventional operation method can not weld aluminum, if argon is used, the tungsten electrode is connected, the aluminum can be welded, but the tungsten electrode burns out quickly, and it can be used temporarily, especially when the current is relatively small, such as below 50A. Of course, it is better to use an AC argon arc welding machine.

The inverter DC argon arc welding machine welds aluminum, and a thin tungsten rod is added in front of the cooling water for arc strike, which can be used to weld aluminum plates of about one centimeter.

DC argon arc welding machine can not weld aluminum, welding aluminum must use AC and DC argon arc welding, if you need a beautiful welding bead, use AC and DC argon arc welding machine with pulse, try to use water-cooled welding gun.

It is not very difficult for an already mature TIG welder to weld aluminum, mainly remember the following points:

1) To use an AC argon arc welding machine. Cathodic crushing is used to target aluminium oxide (alumina) produced during the welding process.

2) The choice of black glass. It should be one or two sizes larger than your usual welded stainless steel lenses for a better view of the molten pool.

3) Appropriate material selection. Choose the appropriate filling material according to the material of the aluminum part.

4) Selection of gases. Argon-rich (nitrogen + argon) and argon can be used.

5) Selection of current. It depends on personal habits.

If you want to communicate, you can weld aluminum, and if you don't understand, you can consult 0595-22429297

Welders are harmful jobs, and argon arc welding is the most powerful, so don't enter this line if you can.

In the first half of his life, he exchanged his life for money, and in the second half of his life, he used money to treat his illness.

Not all TIG welding machines can weld aluminum, it depends on whether there is a functional option for welding aluminum on the panel of the welding machine;

Your machine is too small, and it takes a lot of current to weld aluminum, I remember it seems to be more than 280A.

The argon arc welding machine cannot weld aluminum, and the welding of aluminum requires a professional welding machine for aluminum welding.

You're a DC welder, you have to use AC. DC TIG welding can only weld stainless steel.

Pulse.

Or when welding, poke it with an electrode to pierce the oxide film and weld.

WHME's welding machine can only weld aluminum, that is, it has to use the way of communication.

What kind of welding machine are you talking about for a long time?

You asked this question, and you don't say anything about the specific situation, why don't you ask why you can't go to heaven?
