一、国内概况自五十年代中期摩擦焊工艺开始用于生产以来,越来越显示出它的优越性。所以工具、汽车、拖拉机、电机制造、锅炉以及地质、石油勘探等行业均给予极大的重视,并生产了各种专用的摩擦焊机。能够使用摩擦焊接方法进行加工的产品 First, the domestic profile Since the mid-fifties friction welding process began to be used, more and more to show its superiority. Therefore, tools, automobiles, tractors, motor manufacturing, boilers and geology, oil exploration and other industries have given great importance, and produced a variety of special friction welding machine. Products that can be processed using friction welding methods
