无铅黄铜的焊接方法;Welding method for lead-free brass

摘要

一种无铅黄铜的焊接方法用以避免焊后之无铅黄铜发生脱锌(dezincification)的现象，其包含：提供一无铅黄铜基材，该无铅黄铜基材具有一待焊区域及一间隙；一研磨步骤，研磨该无铅黄铜基材之该待焊区域以去除位于该待焊区域之表面氧化物；一清洁步骤，清洁该无铅黄铜基材之该待焊区域以去除杂质与污染物；一固定步骤，以一夹具固定该无铅黄铜基材；以及一焊接步骤，沿该间隙进行焊接而形成有一焊道，且该焊道并无发生脱锌的现象。; a grinding step for grinding the welding area of the lead-free brass substrate to remove a surface oxide disposed on the welding area; a cleaning step for cleaning up the welding area of the lead-free brass to remove a impurities and a contaminant; a fixing step for fixing the lead-free brass by a fixture; and a welding step for forming a weld zone by welding along the interval, and dezincification has not occurred on the weld zone.
