Problems solved by technology

[0008] The disadvantage of the connection according to DE102007060116A1 is that it must be processed with a flux in order to ensure that the melt flows onto the steel pipe
Such fluxes are often highly corrosive and thus adversely affect the durability of the connections thus produced

Embodiment Construction

[0047] figure 1 A cross-sectional view of a mixing element 1 produced with the method according to the invention is shown. The hybrid component 1 here comprises a hollow profile 2 made of steel and a component 3 made of aluminum. The hollow profile 2 is of rectilinear design at its end 4 close to the component 3 . The hollow profile is mounted on the pipe butt shape of member 3 on the protrusion 5. Within the scope of the invention, a press-fit seat 6 can also be formed between the tube-butt-shaped projection 5 and the end 4 of the hollow profile 2 .

[0048] A material-bonded connection is produced between the end 4 of the hollow profile 2 and the component 3 . The material-bonded connection is characterized in that it is also produced in the joint region 8 by means of the joint seam 7 , welding filler material and a welding torch (not shown here).

Abstract

In a method of producing a material joint between a hollow section (2) of steel and a structural element (3) of an aluminum material, the hollow section (2) is aligned in relation to the structural element (3) in a coupling position. The hollow section (2) and the structural element (3) are mutually aligned, and the hollow section (2) is connected with the structural element (3) by thermal joining, using inert gas shielded arc welding. A welding torch is hereby positioned at an angle of 20 DEG to 40 DEG in relation to an axial direction in a welding position PA in relation to a to-be-welded joining seam, and the axial direction is oriented in parallel relationship to a longitudinal axis (15) of the hollow section.

Description

technical field [0001] The invention relates to a method for producing a materially bonded connection having the features of claim 1 . [0002] Furthermore, the invention relates to a hollow profile connection with the features of claim 21 . Background technique [0003] To join individual components made of steel and aluminum, non-thermal joining methods such as riveting or screwing are often used. In this case, the different components are connected to each other by means of a positive fit with rivets or screws. However, due to its point-like force transmission, the strength of this connection is always limited. Also, in order to insert the rivets or bolts, it is also necessary in principle to remove material, which brings about an additional weakening in the area of ​​the connecting point. [0004] The conversion of steel-aluminum-hybrid components has great potential for weight reduction and improved product properties, especially in the aerospace and automotive techn...
