What is Post Weld Heat Treatment (PWHT)? WELDING

In steel fabrication,the most common PWHT procedures applied are post heating and stress relieving.When we weld,we introduce enough heat to melt the base material.This elevated temperature causes microstructural changes to the base material which can change very important material properties such as tensile strength,hardness,ductility and Weldox 700 Steel Plates Suppliers and Manufacturers S690QL Q690 high strength steel plate price Product Description This product is the yield strength 690MPa quenching and tempering high strength steel plate,can be used for mining and all kinds of construction equipment,such as drilling,shovel,electric wheel dump truck,excavators,loaders,Structural Parts for Heavy Equipment SINOMACHSINOMACH terminal tractor is constructed with reliable parts purchased from KALMAR,a subordinate brand of CARGOTEC.Using high-grade Q690 steel plates,our IWE (international welding engineer) qualified welders ensure the strength and rigidity of each welded tractor framework.
