 ABSTRACT: This paper designs and studies a saddle weld welding robot suitable for heavy pressure vessels. The mathematical model of saddle weld is established by geometric method, which provides a theoretical basis for the design and kinematics simulation of welding robot mechanism. The composition and working principle of the welding robot body mechanism are introduced, and the robot body mechanism is designed. The virtual prototype of the welding robot was built using Solidworks software and imported into Adams software for kinematics simulation. The welding experiment was carried out on the optimized welding robot. The test results show that the welding robot has stable welding quality and can meet the requirements of the saddle weld welding operation of heavy pressure vessels.
