埋弧自动焊应用主要是中国石化兰化化建公司机械厂焊接压力容器,可焊接直径为1000～5000mm,厚度为8～40mm 的碳素钢及低合金钢制压力容器的纵、环焊缝。1991年试验成功采用埋弧焊焊接不锈钢耐腐蚀层堆焊工艺,已用于实际产品生产中,取得良好的效果,节约资金2万余元。今年2月又成功的将 The main application of submerged arc welding is welding pressure vessels of Sinopec’s Lanhua Chemical Construction Machinery Plant. It can weld longitudinal and girth welds of carbon steel and low alloy steel pressure vessels with diameters of 1000-5000mm and thickness of 8-40mm. . In 1991, the test successfully used submerged arc welding of stainless steel anti-corrosion layer surfacing technology, has been used in the actual production of products, and achieved good results, saving more than 20,000 yuan of funds. In February this year, it will succeed again
