摘要
A method is described for joining two sheets (1, 2) of aluminum material on the one hand and iron or titanium material on the other hand by a welding-soldering joint by using a filler, with the iron or titanium material being provided at least in the joining region with a coating preferably on the basis of zinc or aluminum before the filler is applied by forming a weld seam (4) under melting. In order to provide advantageous joining conditions it is proposed that the two sheets (1, 2) are joined in the form of a butt-joint, with the filler on the basis of aluminum being applied for the formation of the weld seam (4) on both sides of the sheet in a region bridging the joint onto the sheet (1) made of iron or titanium material in a width (b) corresponding to at least three times the thickness (d) of said sheet (1).
