液压油缸焊缝渗漏问题的解决

Solution about the Weld Leakage of Hydraulic Cylinder

针对液压油缸因焊缝缺陷造成的渗漏现象,进行了焊接试验和工艺优化完善,最终通过确定焊接位置、设计专用密封试验工艺装备并增加焊缝密封试验等措施,解决了液压油缸渗漏油问题,并为后续类似结构的液压油缸加工总结了经验。

The welding experiment and process optimization has been finished for the weld leakage. Finally, the problem is solved by determining the welding position, designing the special process equipment of sealing test and increasing weld seal test, etc. The experience is summed up for the the hydraulic cylinders with the similar structures.
