Straight Seam Welders for Round and Square Duct and Cylinders
Vertical welder for round and square duct without changing fixtures, plus a laser-tracking welder for small cylinders
Overview
What it does
The vertical seam welder stands the duct section upright and runs the torch down the longitudinal seam. It switches between round and square duct at the touch screen, without changing the clamping fixture or the copper backing bar, so one machine covers both shapes.
It welds stainless steel, carbon steel and galvanized sheet by TIG or MIG/MAG, round ducts from 250 to 1600 mm in diameter and square ducts from 220 x 220 mm, up to 1500 mm long. Internal and external gas shielding can be added for a cleaner stainless weld, and an anti-collision mount protects the torch.
For small cylinders there is also a seam welder with laser seam tracking: it finds and follows the joint itself, without a jig, on tubes 100 to 400 mm in diameter and 0.8 to 1.5 mm thick.
