摘要
通过对磨损的采煤机截齿材质焊接性分析,采用药芯焊丝MAG焊和焊接工艺措施进行表面堆焊修复,焊后热处理使截齿获得良好的硬度、韧性和耐磨性等综合性能,提高了截齿的使用寿命。
Through analysing welding properties of wear coal mining maehine bit tooth, pile welding is used by MAG and welding handicraft measures, integrative nature is repaided on hardness, impact toughness, abrassion resistance etc., by heat treatment after welding, the life of bit tooth has been improved.
