Note: Seam welding produces gas-tight/liquid-tight welds. Continuous seams give complete overlap; stitch seams allow cooling between spots.

Reference

Seam Welding Parameters: Nugget diameter: d = 4*sqrt(t) mm Continuous seam current: I = 5.5*sqrt(t) kA Stitch current: I = 6.0*sqrt(t) kA Overlap % = (nugget_d - pitch) / nugget_d * 100
