How to weld aluminum profiles What is the general equipment like 10

Equipment: TIG welding machine.

Welding material: aluminum welding wire.

Aluminum is generally welded with aluminum argon arc.

If it is a small repair factory, or a special welding store, or mainly repairing or processing small aluminum alloy parts, it is highly recommended to use aluminum argon arc welding, rather than pulse gas shielded welding.

Because the control of the quality and detail of the weld output of aluminum-TIG welding is not possible with the output of the pulsed gas shielded welding machine.

If it is a batch of large-thickness aluminum sheet welding processing, or a batch of structural parts processing, in addition to the strength requirements for the quality of the weld, other requirements are not high, it is suitable for double pulse gas shielded welding.

Precautions for welding aluminum:

Before welding, we need to understand the properties of these materials. Thermal conductivity and specific heat capacity of aluminum alloys.

All are carbon steel.

and 2 times more than low-alloy steel. The thermal conductivity of aluminum is austenitic stainless steel.

more than a dozen times. During the torch welding process, a large amount of heat is rapidly conducted into the base metal, making it difficult to form a molten pool.

The use of small inner diameter gas pipe leads to too narrow protection range and excessive gas blowing force per unit area: for example, when a single copper pipe with an inner diameter of 4mm is used for protective gas protection, and the sample is placed vertically, due to the large fluidity of the liquid aluminum alloy, under the action of the protective air blowing force and its own gravity and other factors, the aluminum alloy in the molten pool is easy to flow down in the direction of gravity, resulting in the collapse of the weld after welding.

Hello dear, I'm honored to answer for you! (1) Simple manual tungsten DC argon arc welding machine. Commonly used simple manual tungsten DC argon arc welding machine.

It is made of a DC welding machine (ZX-400 or ZXG-300) and an argon cylinder, with an electrical connector and a gas valve directly connected to the gas pipe and cable to the welding torch, which can be used for welding. (2) Manual tungsten AC argon arc welding machine. The commonly used manual tungsten AC argon arc welding machine is NSA-500-1 type.

It is composed of BX3-500 welding transformer, welding torch, control box, argon cylinder. AC welding machine or AC and DC welding machine can be used to weld aluminum plates, and 300A is OK. Hope it solves your problem!

According to the welding process requirements, the specific material of aluminum, the thickness of aluminum, the size of the welding amount and other factors, choose a cost-effective welding method.

According to the specific material of aluminum, the thickness of aluminum, the size of welding volume and other factors, cost-effective welding methods are often selected.

The welding machines available for aluminum are: AC tungsten argon arc welding machine; DCTIG DC tungsten argon arc welding machine; MIG Melting Pole TIG Welding Machine; laser welding; plasma welding; ZX5 thyristor electrode hand arc welding machine; ZX7 inverter DC electrode hand arc welding machine.

Summary. Hello, aluminum is generally gas welded.

Hello, aluminum is generally gas welded.

Gas welding can be used for repair welding of aluminum sheets and castings that do not require high welding quality, electrode arc welding can be used for repair welding of aluminum alloy castings, inert gas shielded welding is the most widely used aluminum and aluminum alloy welding method, aluminum and aluminum alloy wide plate can be tungsten AC argon arc welding or tungsten pulse argon arc welding, aluminum and aluminum alloy thick plate can be tungsten helium arc welding, argon-helium mixed tungsten gas shielded welding, MIG/MAG welding, pulse MIG/MAG welding.

Hope mine can help you thank you!

1. Tungsten argon arc welding.

Aluminum and aluminum alloy sheets can be tungsten AC argon arc welding or tungsten pulse argon arc welding, the equipment is more complex, and it is not suitable for operation under open air conditions.

2. Resistance spot welding, seam welding

The welding current is large, the productivity is high, and it is suitable for mass production of parts and components, and aluminum alloy resistance butt welding, which can generally only be used for the overlapping welding of plates and plates below 5 mm thickness, or the overlapping welding of bars and bars below 10 mm.

3. Pulse argon arc welding.

The weldment deformation is small, and the heat affected zone is small, which is especially suitable for thin plates.

4. Low temperature flame welding.

The welding tool can be used in the third generation of the derivative version of the liquefied gas spray gun, and then with the low-temperature aluminum wire welding, the commonly used is Viodin 303 low-temperature aluminum electrode, which is generally welded at 179 temperature.
