Attempting to braze a contaminated or improperly cleaned surface will result in an unsatisfactory joint. 在被污染或未经正确清理的表面进行铜焊,其焊接效果将不会令人满意。
The technology of developing quality and strong pick is found by researching the hard metal alloy, pick-body material, weld gap, technique of braze welding and heat treatment. 通过对硬质合金、齿体材质、缝间隙、焊及热处理工艺的研究,寻找出了研制优质强力截齿的技术途径。
