焊接是锯片制造中一道极其重要的工序. 锯齿和基体间要有足够的焊接牢度; 焊接位置要正确; 焊接温度不能过高, 以免损害锯齿; 焊接时间要短, 以免引起基体变形; 因为高温会引起金刚石和结合剂氧化外, 还会引起基体表面局部变形, 退火, 晶粒增大, 从而产生焊接应力. 焊接温度一般在600~800℃之间. 焊接工艺流程见图195. 图195 锯片焊接工艺流程 为了使焊接工作顺利进行, 焊接件的结合面上必须涂刷银钎焊剂, 目的是促使被焊物表面氧化物还原, 促进银焊片的熔融, 改善焊片的流动性等. 选择焊片要满足以下要求: 1焊片的熔化温度要低于锯齿的熔化温度, 一般温差在100~200℃之间. 如果温差过小, 有可能在焊接时使锯齿中的低熔点成分熔融, 影响焊接质量. 2焊片的性质, 其和钢体和节块的可焊性应......
