摘要
根据我国焊接规范的规定,强度等级越高的钢材,要求作消应热处理的钢板厚度相对越薄。大的钢管只能采用局部热处理方法,要使温度控制恰当且均匀,非常困难。本文主要介绍对水电站压力钢管焊接消应热处理的一些认识。
According to the norms of welding, the higher strength grade of steel, heat treatment required for elimination of the plate thickness should be relatively thinner.Large steel heat treatment method can only be used locally ,to make proper and uniform temperature control is very difficult.In this paper,the pressure on the station should be hardened and welded some consumer awareness.
