Abstract:
A new and improved fillet welding equipment is disclosed which can be used to butt a pipe member against a plate-like surface and then weld the entire periphery of the butted pipe member. In this fillet welding equipment, a pair of welding torches are arranged such that their respective nozzles are opposed to and spaced about 90 degrees from each other. This pair of welding torches can be rotationally moved simultaneously and continuously through their respective predetermined ranges of about 90 degrees to weld one half round section of the entire periphery to be welded, which results in the reduced welding time.
