AbstractWelding quality sheet forming side welding by welding equipment, consumables, process, operational technical limitations. This paper describes in detail the welding power, welding current, welding speed, arc voltage, welding layers, welding class shape, electrode diameter and other factors on the process side welding sheet metal forming technology and related welding quality caused by defects. Detailed analysis of the reasons for the poor quality of the sheet side welding forming a series of problems caused by poor technical quality of welding and the resulting proposed appropriate measures to prevent, resolve defects sheet forming side welding technology, the single sheet surface welding forming technology has been refined to promote them, and the sheet forming side welding job with some guidance.

Keywords: thin side welding forming, welding, quality, Reason
