Laser hybrid welding method and laser hybrid welding torch using a zinc and/or carbon and/or aluminum-containing rod |
摘要 |
The invention relates to a method for welding coated sheet metal (3), which comprises at least one laser (13) and at least one shielded arc unit (5) and a rod feeding device (11) for a welding rod (12). The aim of the invention is to provide a method or a device of the aforementioned kind which allows fo~ reducing or completely avoiding inclusions such as are e.g. caused by the evaporation of the coating of the metal sheet (3). For this purpose, a clamping device (6) is used for positioning the coated metal sheet (3) without substantial gaps between the individual sheets. A material having a zinc and/or carbon and/or aluminum content is used as the weld metal or welding rod (12).
