为了提高特殊高强度气体放电灯(HID)的钼丝与镍丝焊接强度的可靠性,在电阻焊接的过程中对灯丝焊接深度进行实时检测,焊接深度达到预设定值后及时切断焊接脉冲,从而提高了焊接强度的可靠性,为此在焊接设备上引入一套焊接深度位移控制系统,并在生产中建立焊接深度的统计方法的工艺控制(SPC)控制后,焊接质量明显提高,有效控制了最终检验焊接不牢靠的废品率。
In order to improve the reliability of the welding strength of molybdenum wire and nickel wire of special high intensity discharge lamp (HID), the welding depth of the filament was detected in real time in the process of resistance welding. After the welding depth reached the preset value, the welding pulse was cut off in time, Thereby improving the reliability of the welding strength. To this end, a set of welding depth displacement control system is introduced into the welding equipment, and the process control (SPC) of the statistical method of welding depth is established in production, the welding quality is obviously improved and the effective control The final test welding is not reliable scrap rate.
