Embodiment Construction

[0028] according to figure 1 A known method for joining together two sheets 1 and 2 with different melting points in a cohesive manner is shown. The end plate 1 therefore has an aluminum material or an aluminum alloy and the connecting plate 2 has a steel material. It is known to provide on the connecting sheet 2 a cut joint edge 3 which forms joint surfaces 3 ′ and 3 ″ which are inclined towards each other, that is to say a V-shaped end. The joint edge 3 hits the end sheet 1 , Rather, it hits the blunt joining edge 4 of the end sheet metal. When the contacting sheets 1 and 2 are spliced ​​together, the additional material 5 is now used (additional material 5 is Image 6 only schematically shown in ), wherein the quality in the splicing area 6 after the brazing method is improved, additional material is introduced into this splicing area 6 , which is achieved by the welding device 7 . This welding device 7 is now in the figure 1A cohesive connection is established between t...

Abstract

The invention relates to an apparatus and to a process for cohesively joining two plates (1 and 2) having differing melting points, one of which plates, the end plate (1), comprises a light metal material, in particular aluminium material, and the other of which plates, the connecting plate (2), comprises an iron and/or titanium material, wherein a coating (9) preferably on the basis of zinc or aluminium is provided at least partially on at least one of the abutting faces (3', 3'') of the abutting edge (3) of the connecting plate (2) which extend inclined with respect to one another, in which process both plates (1 and 2) are joined together by braze welding so as to abut against one another along their common joint using an additional material (5) on the basis of light metal, in particular on the basis of aluminium. In order to provide advantageous process conditions, the invention proposes that a recess (10) be made, before joining, in the abutting edge (4) of the end plate (1) for receiving at least part of the coated abutting edge (3) of the connecting plate (2), wherein, during joining, braze welding is carried out at least partially over a flank (11 or 12) of the recess (10) overlapping the coating (9) of the connecting plate part.

Description

technical field [0001] The invention relates to a method for the cohesive splicing of two sheets with different melting points, of which one end sheet comprises a light metal material, in particular aluminium, and the other connecting sheet comprises iron Material and / or titanium material, wherein a coating, preferably based on zinc or aluminum, is at least partially provided on at least one of the joining surfaces of the joining edges of the connecting sheet metal that are distributed obliquely to each other, in this method, The two metal sheets are joined together in a brazed manner along their common joint using an additional material based on aluminum. Background technique [0002] In order to be able to join the steel sheet and the aluminium sheet together in a cohesive manner, it is known from the prior art (WO2004030856A1 and WO2006012659A1) to provide a coating on the cut joining edges of the steel sheet so that the aluminium melted by the brazing method can be Coat...
