What welding is used for stainless steel?

Use argon arc welding machine to connect.

Argon arc welding machine is adopted, which is a construction method with gas protection. During operation, because inert gas will surround the welding core, the welding core will not contact with oxygen when melting, so oxidation will not occur. 2. The flux-cored wire is used to weld stainless steel with carbon dioxide gas, and its efficiency is 5-6 times that of ordinary covered electrode.

This welding method is very simple and can be used to weld almost all materials. Outdoor use, good adaptability, even underwater use. Most electric welding machines can carry out tig welding. In electrode welding, the arc length depends on the human hand: when you change the gap between the electrode and the workpiece, you also change the arc length. In most cases, direct current is used for welding.

What are the precautions for welding stainless steel profiles?

1, stainless steel profile has excellent thermal conductivity and hot melt performance, and its linear expansion coefficient is large, so it is more troublesome to weld. Corresponding welding methods should be adopted in construction to ensure excellent welding quality.

2. It is inevitable that residues will splash out during welding construction, so for our own health, it is best to bring protective equipment in advance, such as helmets and eye masks.

3. Splash must be treated when welding, otherwise it will be attached to the outer layer of stainless steel profile carelessly, shortening its service life, so it is best to coat splash inhibitor on the welding joint.

4. During welding construction, if the operation is improper, it is very easy to leave defects on the outer layer, such as damaged protective film, so it is necessary to strike an arc on the weld bead and melt the solvent into the weld.
