Cold Formed Steel - Weldability

Weldability

Weldability refers to the capacity of steel to be welded into a satisfactory, crack free, sound joint under fabrication conditions without difficulty. Welding is possible in cold-formed steel elements, but it shall follow the standards given in AISI S100-2007, Section E.

1.When thickness less than or equal to 3/16” (4.76mm):

The various possible welds in cold formed steel sections, where the thickness of the thinnest element in the connection is 3/16” or less are as follows

• • Groove Welds in Butt joints
  • Arc Spot Welds
  • Arc Seam Welds
  • Fillet Welds
  • Flare Groove Welds

2.When thickness greater than or equal to 3/16” (4.76mm):

Welded connections in which thickness of the thinnest connected arc is greater than 3/16” (4.76mm) shall be in accordance with ANSI/AISC-360. The weld positions are covered as per AISI S100-2007 (Table E2a)
