Abstract

See full text

In a method of producing a material joint between a hollow section of steel and a structural element of an aluminum material, hollow section is aligned in relation to the structural element in a coupling position. One end of the hollow section is placed upon a shoulder of the structural element, and the end of the hollow section is connected with the structural element by thermal joining, using inert gas shielded arc welding. A welding torch is hereby positioned at an angle of 20° to 40° in relation to an axial direction in a welding position in relation to a joining seam to be realized, and the axial direction is oriented in parallel relationship to a longitudinal axis of the hollow section.
