ABSTRACT:
A method and apparatus for welding hollow elongated beams wherein the plates forming the beam are tack-welded together in proper relationship and all corners of the beam are simultaneously and continuously welded by moving a multiple head welding carriage along the length of the beam in order to minimize warpage and longitudinal deflection of the beam due to the welding heat.
