补充资料:焊接:摩擦焊
利用工件端面相互摩擦產生的热量使之达到塑性状态﹐然后顶锻完成焊接的方法。车削工件时切屑往往牢牢地黏在刀头上﹐轴与轴瓦之间润滑不良时也会產生局部焊合﹐摩擦焊就是从这些现象出发而发明的。摩擦焊可分为连续驱动摩擦焊和惯性摩擦焊两种。①连续驱动摩擦焊﹕由电动机带动一个工件旋转﹐同时把另一工件压向旋转工件﹐使其接触面相互摩擦產生热量和一定塑性变形﹐然后停止旋转﹐同时施加顶锻压力完成焊接(图1 连续驱动摩擦焊 )。焊接质量与转速﹑摩擦时间﹑摩擦压力﹑顶锻压力和工件顶锻变形量有关。②惯性摩擦焊﹕由电动机驱动飞轮达到要求的转速﹐然后把一个工件压向夹持在飞轮轴上的转动工件﹐工件间的摩擦阻力使飞轮减速﹐并将飞轮的动能转换成焊接所需的热能(图2 惯性摩擦焊 )。焊接质量与飞轮惯性矩﹑转速和顶锻力有关。摩擦焊所用的摩擦焊机包括驱动系统(惯性摩擦焊机还包括飞轮)和加压装置。全自动焊机还有上﹑下料装置﹑去飞边装置和参数自动监控系统。摩擦焊适合於焊接杆件和管件﹐工艺简单﹑质量好﹐劳动条件好﹐生產率高﹐耗电量少﹐易於机械化和自动化。摩擦焊在工厂生產线上广泛用於发动机燃烧室﹑排气阀﹑轴﹑轴套﹑杆件﹑管子与法兰﹑石油钻杆和钻芯的连接和变截面杆件的连接。接头焊后不会產生金属间化合物。摩擦焊也常用於异种金属焊接﹐如铝与铜﹑钢﹑镍﹑镁合金﹔铜与钢﹑银等。摩擦焊在铝-铜导线过渡接头的焊接方面应用尤广。惯性摩擦焊也可焊接直径为 100毫米的棒材或截面积为60厘米2的管件。
