采用激光焊接超细预合金粉胎体,开发了新的薄壁钻产品,通过对与现有的产品工艺、性能测试以及实际使用分析对比,结果表明:激光焊接与普通钎焊相比结合强度提高2~3倍,克服了胎体脱落问题,胎体耐磨性提高了50%~120%,其中轴向磨损速率提高1.2倍;钻削速度提高30.4%,工矿适应性增加,使用寿命提高25%~108%。 The laser thin-alloy pre-alloyed powder carcass was developed to develop a new thin-walled diamond product. Compared with the existing product technology, performance test and practical use analysis, the results show that the laser welding compared with ordinary brazing strength Increased 2 ~ 3 times, overcame the problem of carcass shedding, the wear resistance of the carcass increased by 50% ~ 120%, axial wear rate increased by 1.2 times; drilling speed increased by 30.4%, industrial and mining adaptability increased and service life increased 25% ~ 108%.
