Abstract
A method of preventing base metal end cracks in arc welding characterized by the adaptation of an end tab having three protuberant portions on its end contacting the base metal, wherein the protuberant portions at both ends of the end tab are positioned in abutment on the parts of the base metal which are on both sides of the groove line where the welding arc and the weld metal are not directly contacted, while the protuberant portion in the center is positioned on an extension of the groove line, and welding is carried out with the end tab secured to the welding end of the base metal.
