FILLER METAL SHAPE FOR WELDING

摘要

Provided is filler metal for welding which has a wider heat flow area than general wire filler metal and is stable because the heat input amount per unit length is increased. The filler metal for welding is melted by energy continuously supplied from a welding machine, which is located on the top of a base material, to the top end of the base material. The cross section of the filler metal is in a shape that the surface facing an electrode is concavely bent toward the electrode.
