A method for the production of a welded connection in a joint gap and process before the direction of observation

摘要

In the manufacture of a welded connection between the material edges (9) in a joint gap (2) of a metallic workpiece (1) with the use of a welding beam generator, with which a welding beam (4) of a first side of the metallic workpiece (1) on the joining gap (2) is directed to a welded connection of the material edges (9) over the entire depth of the joining gap (2), and an optical detection device (5), with which one of the welding beam generator facing away from the surface of the workpiece (1) of a second side of the workpiece (1) is imaged in order to optically a during the welding process, the existing molten bath (10) to detect and evaluate with an evaluation stage, a process for the purpose of quality assurance observation of the welding process is carried out in a simple manner in that, with the optical detection device (5) and the evaluation stage, at the same time, the position of the furnace (10) and the position of the joining gap (2) is determined and the relative position with respect to one another as a parameter for the readjustment of the positioning of the welding beam (4) relative to the joining gap (2) is made available.
