Throughout the GTA welding (GTAW) process, bead width (Bw), height (Bh), penetration depth (Dp), and metal transfer modes change in accordance with current wire feeding speed. Various processes employing GTAW include text marking systems that have as main management items, some such require sufficiently complete penetration. It is judged there will also be a type advantageous for first layer of...

Sustainability scores can be used to assess manufacturing strategies, going one step beyond a standard economic assessment. This work uses previously proposed methodology evaluate two of the most common welding processes for aluminium alloys that are specifically in fabrication components transport industry based on their advantages generating lightweight and dimensionally efficient parts. For ...

this paper deals with the investigation of the microstructure and hardness of steel samples cladded with satellite 6-wc composites by using gas tungsten arc welding (gtaw) process. for this purpose, steel samples were coated with unreinforced and reinforced stellite (by 20, 30 and 40 wt.% wc). the cladded samples were evaluated by metallographic studies, microhardness measurement and x-ray diff...

The hardfacing deposition with the GTAW process is widely studied addition of metallic powder or solid wire. This study introduces an original method, flux-cored-double-wire (FCDW-GTAW), where wires different compositions are used simultaneously to deposit hardfacing. Because complexity in stabilizing welding system, combined effects parameters should be investigated, allowing elaborate predict...

The anisotropic, heterogeneous and coarse granular structures of austenitic stainless steel welds lead to important disturbances of the ultrasonic propagation: beam skewing and splitting, attenuation, backscattering and spurious echoes. These disturbances have been studied by EDF R&D for a few years in order to improve the ultrasonic NDT in nuclear applications. In particular, a methodology for...
