本文研制的YD型硬质合金复合材料堆焊焊条在性能上达到了国外同类焊条水平。代替原有的管装粒状碳化钨硬质合金堆焊焊条,用来堆焊石油井下工具,其工作效率和使用寿命得到显著提高。
The developed YD-type carbide composite surfacing electrode in the performance reached the level of similar foreign electrodes. Instead of the original tube filled tungsten carbide carbide welding electrodes, tools used to build up the underground welding tools, its work efficiency and service life has been significantly improved.
