ZOZEN welding technology of horizontal fixed tubes

The welding of horizontal fixed tubes is to weld the tubes which are put in the horizontal or nearly horizontal position. This kind of welding includes three spacial positions: upright, vertical and horizontal (all-position), which puts forward high requirements for the welding technology. Facing the difficulties brought by welding appearance requirements, curvature of tube joint, and small tube diameter, ZOZEN workers are skilled in welding to ensure the welding quality to effectively extend the service life of boilers.
