摘要: <正>在锯条端头焊接过程中,焊缝和热影响区在热源的作用下,受到某种程度的加热和相变,发生组织和性能的变化,其机械性能有所下降。 本文概述了不同焊接法带锯条的焊缝机械性能所作的测定,并对焊缝进行了金相分析,找出了焊缝强度变弱的原因;同时对今后进一步提高焊缝强度,改进焊接技术提出了建议。

Abstract: In welding bandsaw ends, the joint and the material near it are heated and metallographically affected. Hence, changes in structures and properties take place and the mechanical properties deteriorate to a certain extent.This paper makes a survey of the mechanical properties of the joint weld resulted from different welding processes, gives an analysis of the metallography of the weld, explains the causes of the decrease of strength in the joints and raises some suggestions with regard to increasing the strength of the joint and improving welding techniques.
