Process for thermally joining galvanized or hot-dip galvanized semi-finished materials or workpieces comprises plasma soldering with the introduction of a soldering material to join the parts

摘要

Process for thermally joining metal parts (11) comprises plasma soldering with the introduction of a soldering material (12) to join the parts. The soldering material is added to the soldering process as a fine powder. An independent claim is also included for a device for thermally joining metal parts comprising a plasma burner (13) having a cathode chamber (7) for one electrode (1) and a plasma nozzle (3) from which a plasma beam is produced. Preferred Features: The soldering material is conveyed using a conveying gas, especially an inert gas, which is introduced from a storage container via one or more feed lines (6).
