Pipe To Flange Stations

HL Longitudinal Seam Welding System

The system suits slip-on flange four-fillet-seam welding simultaneously, pipe to flange, taper pipe to flange. The system can be used in shipbuilding, maritime work, engineering machinery and other industries.

Applications

According to requirement of customer, the system uses pulse MAG welding procedure to deal with root pass, filling pass and cap pass, which realize no spatter welding for reducing line heat input in welding. Through expert parameters in power source, it can realize uniform forming and handsome welding joint under any welding current.
