焊接等径三通的应力测定

Stress Determination of Welded Equi-Diameter Tee Joint

管道系统中有大量的三通部件在工作过程中主要承受内压作用，与此同时，由于管系的自重、温度变化、装配误差、管道位移等原因，使连接三通的支、主管端分别受到各种形式的内、外载荷作用。本文通过对两个φ152mm×20mm焊接等径三通的应力测定，分析了内压载荷下经堆焊加宽方式对三通焊道的补强效果及其应力的分布情况，并做出强度评价。

Through streess determination of two φ152mm × 20mm welded equi-diameter tee joint,this article analyses under internal pressure load and through surfacing widened pattern the reinforced effects and its stress distribution situation of the tee joint weld path and makes the intensity appraisal.
