Abstract
The purpose of this research is to investigate the effect of repair welding process on stainless steel to carbon steel orbital pipes joint generally, repair welding is applied to meet the requirement of conversion in mechanical properties and variance in working conditions. In this study stainless steel grade AISI 304L and carbon steel grade BS1387 are used as a research materials due to their difference in properties and applications. Repair welding is performed in order to extend the service life of the steel made structure when there is a failure happen caused by service deterioration during fabrication stage. However the repetitive heat input on the same weldment during the repair welding process will cause the change in the structure and mechanical properties of the materials. In this study the weld is repaired by using Gas Metal Arc Welding (GMAW) and the welding parameters were welding current, voltage and speed. This research will investigate the effect of welding performance on tensile strength and the height of the weld bead were analyzed by using DOE Taguchi Method. The results of the testing showed that the height of weld bead increases with the increasing of current and speed but decreasing with the increasing of voltage. The tensile strength of the welded material decreases as the increasing of welding current, voltage and speed. So, it can be concluded that the welding parameters give important impact towards mechanical properties of stainless steel to carbon steel orbital pipe joints.
