Loading Thermal Cycles Produced by Welding Steel Molds and X 30 WCrV9 3 and 55 NiCrMoV 6
Journal Title: RECENT - Year 2013, Vol 14, Issue 39
Abstract
The paper presents the influence of thermal cycles upon the thermally influenced area by the loading by welding procedures, 111, 136, 141 EN 287-1/2004 of the materials X 30 WCrV9 3 and 55 NiCrMoV 6 from which hot working moulds are made. The thermal cycles undergone by the test specimens made of the studied materials and the microstructure of the steel X 30 WCrV9 3 and 55 NiCrMoV 6 obtained in different thermal cycles are presented. In the case of loading by welding of the moulds made of steel X 30 WCrV9 3 and 55 NiCrMoV 6, high productivity welding procedures are not advisable, but manual electrical welding and WIG welding.
