Surfacing process test is made on Q235 steel substrate by shielded metalarc welding process using electrode CHR322 at different welding current condition.
This paper mainly introduces the different arc shapes, metal transfer modes, compositions of arc and temperature distribution in plasma-GMAW with different electrode connection forms at present;
