SUG I tanks Permanent and Temporary Attachment Welds#0183;Web viewCompleted welds of new permanent attachments (not including shell-to-bottom welds) and areas where temporary attachments have been removed (API Std 650 tank shell materials of Groups IV,IVA,V,or VI),shall be examined by either the magnetic particle method (or,at the option of the purchaser,by the liquid penetrant method).Weld Distortion - lincolnelectricDistortion in a weld results from the expansion and contraction of the weld metal and adjacent base metal during the heating and cooling cycle of the welding process.Doing all welding on one side of a part will cause much more distortion than if the welds are alternated from one side to the other.The Importance of Correct Post Weld Heat Treatment (PWHT Post Weld Heat Treatment is a mandatory requirement for the fabrication and construction of pressure vessels.The residual stresses formed during welding can cause metal failures.The macro structure also changes during the welding process and makes the steel weak.PWHT removes these stresses and restores the macro structure of the steel.
