激光钎焊方法及搭接接头构件的制造方法
Abstract:
本发明提供一种Al合金与钢板的激光钎焊方法，其能够制造与Al合金的接合强度优异的搭接接头构件。激光钎焊方法包括形成钎焊部(9)的钎焊步骤，所述钎焊部(9)将镀敷层(2)含有1.0质量％～22.0质量％的Al且每单面的镀敷附着量为15g/m2～250g/m2的熔融Zn系镀敷钢板(1)、与Al合金(3)相互接合。
Abstract(English):

The present invention provides a method for laser brazing an Al alloy and a steel sheet. The method makes it possible to produce a lap joint member in which there is excellent joining strength to theAl alloy. A laser brazing method that includes a brazing step in which is formed a braze part (9) that joins an aluminum alloy (3) and a molten-Zn-plated steel sheet (1) that: has a plating layer (2)that is 1.0-22.0 mass% Al; and has 15-250 g/m2 of plating per side.
