H-beam welding lines are used to assemble and weld steel plates into H-beams for heavy steel structure production.

Box beam welding lines cover the complete production flow, starting from raw material loading and assembly, and continuing through tack welding, electroslag welding, double-wire double-arc submerged arc welding, and end-face machining.

Bridge deck U-rib welding lines are used to produce bridge deck panel units for large steel bridge projects, where production volume is high, delivery schedules are tight, and both forming and welding quality need to be kept under close control.
