Pick to: one-sided welding welding quality of double-sided forming by welding equipment, welding material process, operation of the technical level of the restrictions. This paper introduced the welding power source, welding current and welding speed, arc voltage, welding layer, welding rod type of, electrode diameter on technological factors on double-sided one-sided welding forming technology of the influence on the quality of welding and the related defects caused. Detailed analysis of the one-sided welding forming technology of poor quality of welding double-sided caused by a series of problems caused by quality and reasons of the poor, and put forward the corresponding prevention measures to solve, one-sided welding defects of the forming technology of double, double forming technology of one-sided welding perfect further, is extended, and one-sided welding forming of double-sided homework of certain guidance.
Keywords: one-sided welding forming, welding quality, double-sided, reason, measures

Welding technology is one of the important metal processing technology, although welding technology develops very quickly, more and more is also high automation degree, but the manual arc welding is still has irreplaceable position. Especially in small diameter containers and pipe welding, one-sided welding forming the role of welding technology double-sided even more crucial. High quality one-sided welding the weld double-sided forming welding surface should be smooth transition to the mother material, the surface shall not have crack, incomplete fusion, slag, porosity, welding tumor, undercutting the weld defects such as internal also are not allowed to have defects. But the welding process because of equipment, materials, technology and operation and other reasons, make the form can not reach quality requirements, weld and on the structure of the work quality and service life of serious influence.
