Method and apparatus for crack-free welding, repair welding or built-up welding, hot crack more susceptible materials

摘要

A method for crack-free welding, repair welding or resurfacing welding materials is more hot crack by means of a welding process a high power density and a further, with the welding speed in a constant distance from the welding zone effects of the local application of the temperature,characterized in thatthe travelling local application of the temperature on both sides by two parallel or almost parallel to the welding direction (8) and extending to the welding direction (8) extending longitudinally electromagnetically by means of a volume of energy source in the interior of the components 1 and 2 (1, 2) (22) temperature fields generated (9, 10) is carried out,the both in the welding direction (8) in front of the welding zone (4) is to begin and their temperature maximums (13) is outside the heat affected zone (14) and in the welding direction (8) downstream of the solidification zone (6) are locatedand the depth of the temperature fields (9, 10) at the location of the temperature maximum (13) is achieved at least the weld seam depth.
