摘要

An apparatus for welding, designed for theWelding of at least one workpiece with a light arc welding process, in such a way that a liquid sweat said pool from the at least one workpiece is formed, wherein the welding in a direction of advance is carried out; andDirecting an energy beam on a surface of the welding said pool downstream of the light arc welding process, with respect to the feed direction, in such a way that the energy beam of heat energy from said pool of the welding, adds a the form of the welding in order to modify said pool;a weld joint is, of the through the perspiration - and the directing step includes is formed, a cross-sectional porosity of at most 30% and a longitudinally porosity of at most 30% has.
