Study of the effects of welding by two types of fillerwire along with different pre& post heat treatment on weldment mechanical properties of AISI 4130 welded by TIG process

The sensibilities of the high strength steel and ultra high strength steel, their vast applications in strategically industries such as aircraft and shipping and also the different welding problems, outstand the need to investigate the weld ability and mechanical properties of these types of steels. In this research we have selected some test plates according to available standards and joined them together by Vee-Joint. We selected two …
