HZK1220F-TD Tank Welding Machine

For various tank welds on materials like carbon and low-alloy steel ldeal for tank end cap circumferential seamsand barrel longitudinal seam.

Optimized for tanks up to 5000mm in length anddiameters ranging from 1000 to 3000mm.

View Details

During circumferential seam welding, the welding operation is performed using a welding manipulator arm in conjunction with a CNC roller frame to drive the rotation of the weldment.
For longitudinal seam welding, a welding method is employed where the weldment is translated or moved while welding takes place.
