The welding quality of the plate groove of the hydraulic support directly affects the quality of the whole hydraulic support. In order to meet the quality requirements of hydraulic support in current coal production industry, combining with the actual production of hydraulic support, this paper discusses on the optimization of groove welding process of structural members and plates of hydraulic support, the further standardization of groove cutting process and angle, and the groove inspection tooling to improve the manufacturing quality of high-end hydraulic support.
