Abstract : Although considerable process has been made in recent years to process impressively large amounts of steel tonnage through automatic processes, the major application of welding manhours is in field locations using portable equipment. Most of the welding in field locations and aboard ship is presently done manually with stick electrode. Recent developments in the area of semi-automatic welding processes and electrodes offer potentially higher productivity than manual welding in applicable areas. However, the size and weight of wire feeders and the limited distance of 10 or 12 feet from the wire feeder to the gun have seriously limited the applications of semi- automatic welding.
