What should be paid attention to when selecting welding rods?

1. Chromium stainless steel has corrosion resistance (oxidizing acid, organic acid, cavitation), heat resistance and wear resistance. It is usually used for equipment and materials such as power stations, chemical industry and petroleum. The weldability of chromium stainless steel is poor, so attention should be paid to the welding process, heat treatment conditions and the selection of appropriate welding electrodes.

Precautions for welding materials

1. Stainless steel electrode usually has two types: titanium-calcium type and low-hydrogen type. The welding current shall be DC power supply as far as possible, which is beneficial to overcome the redness and shallow melting depth of the welding rod. The electrode with titanium-calcium coating is not suitable for all-position welding, only for flat welding and flat fillet welding; Low-hydrogen coated electrode can be used for all-position welding.
