Abstract

The invention discloses an electromagnetic heating static shaft shoulder friction stir welding mechanism. The mechanism comprises a static shaft shoulder, an electromagnetic heating coil and a stirring needle; the static shaft shoulder is provided with an accommodating cavity, the stirring needle is arranged in the accommodating cavity in a penetrating mode, and the lower end of the stirring needle extends out of the lower end of the static shaft shoulder; and the electromagnetic heating coil is arranged in the accommodating cavity and is fixedly connected with the static shaft shoulder, and the electromagnetic heating coil is arranged outside the stirring needle in a wound mode and can heat the stirring needle after being electrified. According to the electromagnetic heating static shaftshoulder friction stir welding mechanism, the heating effect can be improved, and excessive heating difference of welding workpieces is avoided, so that the requirement of consistent performance of the whole weld joint is met. The invention further discloses an electromagnetic heating static shaft shoulder friction stir welding method.

Description

technical field [0001] The invention relates to the field of friction stir welding equipment, in particular to an electromagnetic heating static shaft shoulder friction stir welding mechanism and method. Background technique [0002] Static shoulder friction stir welding technology is an innovative development of conventional friction stir welding technology. It belongs to solid phase welding technology. Compared with traditional fusion welding, it has the advantages of high quality, small heat input and small deformation. It can effectively avoid melting It eliminates common defects such as pores and cracks in welding, so it can achieve high-quality welding of various metal materials. The principle of static shoulder friction stir welding technology is that the shaft shoulder is fixed and does not rotate, the stirring needle rotates, and the stirring needle is used to rotate and insert the welding workpiece, and then move along the direction of the welding seam of the weldi...
