镀锌板短周期拉弧螺柱焊焊接质量检测仪设计

Design of the Testing Instrument for the Welding Quality of Galvanized Sheet Short Cycle Arc Stud Welding

通过分析镀锌板短周期拉弧螺柱焊焊接质量缺陷产生的原因,设计了一套镀锌板短周期拉弧螺柱焊接质量检测仪,通过检测焊后螺柱上端面与工件表面的垂直距离判断螺柱焊接质量。通过和扭力扳手检测螺柱焊接质量方法进行试验对比,结果表明,采用锌板短周期拉弧螺柱焊接质量检测仪检测效果优于用扭力扳手检测。

Through the analysis of galvanized sheet short cycle arc studs welding defects, a galvanized sheet short cycle arc stud welding quality detector was designed, by detecting the vertical distance between the stud upper end face and the surface of the workpiece to judge the quality of stud welding. Test and comparison of the method of welding quality by using torque wrench, the test results showed that the method of galvanized sheet short cycle arc stud welding quality detector was better than that of using the torque wench detection.
