上海锅炉厂承制的一些产品中有些管板,封头和简体等组件的耐腐蚀层需要进行大面积堆焊。遵照伟大领袖毛主席关于“我们不能走世界各国技术发展的老路,跟在别人后面一步一步地爬行,我们必须打破常规,尽量采用先进技术……”的教导。在一机部焊接研究所的协作下,经过短时期的试验,从一九六七年起采用了带极堆焊新工艺,现已用于超低碳不锈钢的堆焊和在特定要求下的铜镍合金堆焊。
Some products made by Shanghai Boiler Factory bear some of the corrosion resistance of some tubesheet, head and simplified components, which require large area surfacing. Following the guidance of Chairman Mao, the great leader, on “We can not take the old road of technological development in all countries in the world and crawl step by step behind others, we must break the routine and try our best to adopt advanced technologies.” After a short period of trial work, a new process with pole-surfacing has been adopted since 1967 under the cooperation of a mechanical welding institute. Now it is used for surfacing welding of ultra-low carbon stainless steel and under special requirements Copper nickel alloy surfacing.
