Gas tungsten arc welding (GTAW) is important in those manufacturing where it significant to control the mechanical and metallurgical characteristics its weld bead geometry. This work has been committed study influence of oxide fluxes on 4 mm thick 304 austenitic stainless steel plates. The Al2O3 TiO2 were used as an flux powder form are mixed with acetone. prepared mixture applied plate without...

Selecting a process for welding large scale equipment on site demands special expertise due to the numerous variables be considered. This paper is aims applying decision support methodology selection of 16000 cubic meter storage tank welded site. Five processes are chosen select from, namely, Gas Metal Arc Welding (GMAW), Shielded (SMAW), Submerged (SAW), Flux Cord (FCAW) and Tungsten (GTAW). T...

Abstract: AISI 316L steel and Inconel 718 are metals of wide application in industries. The study dissimilar welding between these two materials is technologically important to improve their joint performance. We focused this on the evaluation weldability materials. Three samples welded using a multipass GTAW (Gas Tungsten Arc Welding) process with different parameters were analyzed. microstruc...

Martensitic steels have been successfully employed in resource-based industries where components must endure aggressive conditions. In industrial practice, many parts of these are joined by welding techniques. The aim this work was to understand the influence on wear resistance quenched and tempered carbon martensitic steel subjected dry linear reciprocating sliding micro-wear tests. Weld-joint...
