Abstract
In horizontal position, welding bead has an inclination to become hanging bead by gravity, and this problem makes horizontal welding difficult for high-deposition rate welding. To solve this problem, authors proposed a new concept of welding process, so-called electromagnetically controlled molten pool (ECMP) welding process. In this process the molten metal flow and bead shape are controlled by using upward electromagnetic force.
