Longitudinal Seam Welding Equipment

 • Holding the edges accurately in alignment is difficult for the full length of the parts.

• Tack welding takes time and leads to defects in the area of the tack weld.

• There is little effective chilling of the weld joint area leading to distortion and oxidation of the weld and surrounding area.

• Maintaining the dimensional accuracy of the part is difficult. HanYan longitudinal seam welders provide a solution to these problems. We optimize the welding process, reduce welding costs and improve the welding quality. They are designed for the straight line welding of all weldable materials in thicknesses varying from 0.1 mm to 10 mm. Thicker materials can be accommodated using HanYan’s unique mandrel adjustment capability.
