stainless steel welding process

Using the working principle of tungsten argon arc welding, it uses the arc burning between the non-melting electrode tungsten rod and the weldment as a heat source to make the stainless steel plate self-melt to form a weld. The electric plate and arc zone and molten stainless steel are shielded by argon gas, which is isolated from air. Since argon is an inert gas, it does not chemically interact with metal, nor does it dissolve in metal, so it can avoid oxidation of weld metal and burning of alloying elements. Make the welding process simple and easy to control. For this reason, we have designed the electronic control equipment, so that the surface of the welded seam is smooth and clean, without secondary processing, as long as it is polished, it can be bright and traceless, and the welding seam cannot be found. Argon protection is used in welding, it has low thermal conductivity, high temperature does not absorb heat, so the heat loss is small, and its working voltage is only 8-15 volts.

Main Specifications

1. Weld salt spray test: 24 hours without rust.
2. The tensile strength is not less than the performance of the raw material.
3. The shear strength is not less than the performance of the raw material.
4. The surface of the welding seam is smooth and clean without blisters and cracks, the smoothness is 1.6, and it can reach more than 0.8 after polishing.

Main advantages:

1. The weld surface is smooth and no secondary processing is required.
2. Fast speed and small deformation.
3. The arc is visible, the weld is easy to center, and it can be welded in all positions.
4. Welding various metals, stainless steel, aluminum, copper, magnesium and alloy steel and other materials.
5. The welding seam is firm and does not reduce the performance of the raw material.

It can be widely used in the welding of large and small containers such as barrels and cans of light industrial products. At the same time can also be used in the food industry, medicine and other lines.
