Abstract

Currently, most of the blocks attached of the armored vehicles turret body are made by the technological procedures of manual electrode arc welding and semi-automatic gas shielded arc welding. However, there are some welding defects such as under fusion, crack, and pores. In practice，a hybrid thermal source made of the induction heat source and stud welding worked as an effective process for the large diameter studs and heavy, big steels.

In a comprehensive analysis of the previous advantages and disadvantages of automatic stud welding torch, this paper proposes the optimization of Enhance institutions , electromagnetic, spring preload in the welding torch. Mainly to optimize the design of its key components. Dimensions of mechanical structures of the norms, improve the work efficiency of the electromagnet, using the optimum design of the automatic stud welding torch welding process test results show that the torch has a good performance, can adapt to the complex case of the welding.
