| Abstract: | The influence of welding current on the structure and strength of the welded joint ofmash-seam-welding in ST44 has been studied. It was found that the welding-off-defect is the main reasonfor low strength of welding joint, and the size Of the welding-off-defect will be decreased with the increaseof welding currentat at the infusion-zone and the strength of joint improved. |
