HIGH-FREQUENCY WELDING OF SANDWICH METAL SHEETS

摘要

The invention relates to a method for welding a first composite metal sheet part (1), which comprises at least two metal layers (2) and a layer (3) arranged between the two metal layers that is made of a material having a different chemical composition than the two metal layers, to a second metal sheet part (1'), which is made of a solid metal material (5) or a further composite material (1') having at least two metal layers (2') and a layer (3') arranged between the metal layers that is made of a material having a different chemical composition than the two metal layers. The aim of providing a method for welding composite metal sheet parts, which comprise at least two metal layers and an intermediate layer arranged between the two metal layers, to a second metal sheet part, which is made of a solid metal material or a further composite material having at least two metal layers and an intermediate layer arranged between the metal layers, by means of which method pore-free welded connections can be produced with high process reliability, is achieved in that the metal sheet parts are welded using a high-frequency welding method.
