點焊機定義

　　點dian焊han機ji係xi采cai用yong雙shuang麵mian雙shuang點dian過guo流liu焊han接jie的de原yuan理li，工gong作zuo時shi兩liang個ge電dian極ji加jia壓ya工gong件jian使shi兩liang層ceng金jin屬shu在zai兩liang電dian極ji的de壓ya力li下xia構gou成cheng一yi定ding的de接jie觸chu電dian阻zu
，而er焊han接jie電dian流liu從cong一yi電dian極ji流liu經jing另ling一yi電dian極ji時shi在zai兩liang接jie觸chu電dian阻zu點dian構gou成cheng霎sha時shi的de熱re熔rong接jie，且qie焊han接jie電dian流liu霎sha時shi從cong另ling一yi電dian極ji沿yan兩liang工gong件jian流liu至zhi此ci電dian極ji構gou成cheng回hui路lu，並bing且qie不bu會hui傷shang及ji被bei焊han工gong件jian的de內nei部bu構gou造zao。
