作为一种机械的金属接合方法,摩擦焊接原理是一者对另一者在一定速度下作旋转运动,使交接面发生高摩擦热。当接缝面充分可塑时,停止旋转,并增加轴向力,以锻压固结其接缝。许多年来,英国Easterbrook—Allcard有限公司沿用闪光对焊的方法接合高速切削端的坯料和EN9炭素钢柄部。此方法虽已相当令人满意,但仍有的不足之处,这就是闪光对焊有某些冶金问题、其一是,在液态的阶段中,
As a mechanical metal bonding method, the friction welding principle is that one of them rotates at the same speed with the other one to make the interface have high frictional heat. When the joint face is sufficiently malleable, stop rotating and increase axial force to forge and consolidate the seams. For many years, Easterbrook-Allcard Ltd., of Great Britain, followed the method of flash butt welding to join high-speed cutting end stock and EN9 carbon steel stems. Although this method has been quite satisfactory, but there are still some shortcomings, which is flash metallurgical welding some of the problems, one is that in the liquid phase,
