Abstract

The invention relates to the technical field of welding devices, in particular to an electric-arc welding and friction stir welding hybrid welding system which comprises a driving mechanism, a weldinggun mechanism, a rotary extruding mechanism and a connecting frame, wherein the welding gun mechanism is assembled on the connecting frame in a guiding and slipping manner; a self-adjusting mechanismis arranged on the welding gun mechanism, and is used for adjusting the position of the welding gun mechanism when the rotary extruding mechanism extrudes an additive rotationally so as to keep the distance between the welding gun mechanism and a welding platform unchanged; and the driving mechanism is used for controlling the rotary extruding mechanism to perform rotary extruding operation. By the adoption of the welding system, the rotary extruding mechanism and the welding gun mechanism can move synchronously, so that the cooperativity of the rotary extruding mechanism and the welding gunmechanism is improved, and the standardization of the welding process is ensured; and in addition, through the arrangement of the self-adjusting mechanism, the distance between the welding gun mechanism and the welding platform is always kept unchanged, so that the stability of the welding operation is ensured, and the welding quality is further ensured.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a composite welding system of arc welding and friction stir welding. Background technique [0002] Because the arc additive manufacturing process is a non-equilibrium solidification process and needs to experience multiple heat inputs, it is generally believed that the comprehensive mechanical properties of arc additive materials are lower than those obtained by conventional processing methods. In order to improve the structure and performance of arc-added materials, some scholars in the prior art also proposed to perform auxiliary processing such as micro-casting, ultrasonic impact, and hammering on arc-added materials to improve the stress distribution of arc-added materials and refine the grains. And finally achieve the purpose of arc additive material strengthening with welding deformation. [0003] For example, in the Chinese invention patent application with the ...
