| Abstract: | In order to solve the problems of low qualified rate, high cost and progress delay caused by the casting defects of reduction box for drilling rig, the welding structure and welding process were designed by analyzing the reduction box structure. Through practical verification, the indicators all meet the design requirements. The welding box can completely replace the casting box and have better quality, which creates considerable economic benefits. |
