Abstract:Horizontal butt welding is one of the most commonly used welding technology of steel pipe, and it is widely used. Through the analysis of characteristics of one side welding technology, from the assembly and positioning welding, welding, welding layer filling layer, surface layer welding and so on several key links of process requirements of horizontal fixed tube welding; From arc arc starting point welding, welding rod angle control, the replacement of electrodes, arc and arc etc. the main aspects of the horizontal fixed tube butt welding operation essentials. Through the application practice, it has important significance for ensuring the quality of horizontal fixed pipe welding production.

Key words: one side welding double sided forming technology, horizontal fixed tube, butt welding, application discussion
