点焊的工艺过程为开通冷却水;将焊件表面清理干净,装配准确后,送入上、下电极之间,施加压力,使其接触良 好;通电使两工件接触表面受热,局部熔化,形成熔核;断电后保持压力,使熔核在压力下冷却凝固形成焊点;去 除压力,取出工件××清大圣科×清大圣科电焊条×清大圣 科电焊条设备×清大金桥×清大金桥电焊条设备×清大圣科气化炉&ti mes;www.qhsk.cn×清大圣科科技有限公司×× 焊接电流、电极压力、通电时间及电极工作表面尺寸等点焊工艺参数对焊接质量有重大影响×&ti mes;清大圣科×清大圣科电焊条×清大圣科电焊条设备×清大金桥& times;清大金桥电焊条设备×清大圣科气化炉×www.qhsk.cn&ti mes;清大圣科科技有限公司××
