Stitch Welding BSW 30

The BSW 30 uses ￠2.0–2.2mm copper wire as a filler and shielding medium, preventing oxidation at the weld zone. This eliminates the need for secondary surface treatment and produces a visually clean, structurally sound seam — critical for containers and ducts that carry air, fluids, or gas.

A mechanical positioning clamping device locks the workpiece at a fixed 6mm overlap before welding begins. This removes operator guesswork and ensures uniform joint geometry across the entire 50–1000mm welding length, whether running continuous seam or spot weld patterns.

With a diameter range of ￠100–￠1000mm and thickness capacity of 0.4–1.2mm, the machine handles everything from small HVAC duct sections to large rolled tank shells on a single setup — reducing the need for multiple welding stations on the production floor.

Unlike conventional MIG or open-arc processes, the BSW 30’s welding method generates no sparks. This allows deployment in enclosed workshops or near flammable materials without additional fire-suppression measures, while also protecting thin-gauge workpieces from spatter damage.

The integrated NC welding control interface synchronizes clamping pressure, wire feed rate, and welding speed (2 m/min) into one coordinated cycle. Combined with TIG/GTAW and MIG-MAG/GMAW complementary process support, the system adapts to different material and joint requirements without external controllers.
