The processes of metal additive manufacturing (AM) are no longer confined to rapid prototyping applications and seeing increasing use in many fields for the production tools finished products. ability design parts with practically zero waste, high precision, complex geometry, on-demand fabrication among advantages this approach. One drawbacks technique is productivity rate, as made layer by lay...

This article provides an overview of the influence welding parameters and filler material on changes in heat-affected zone (HAZ) thermo-mechanically controlled processed (TMCP) steel welded joints. The research focused evaluating effect heat input cooling rate width soft zone, which significantly affects mechanical properties negative is more pronounced as thickness decreases. Therefore, object...

The heating and impact of arc droplet acting on the weld pool lead to transfer mass, heat, momentum, which affects dynamic behavior microstructure in P-GMAW process. In this paper, an image processing program is used extract characteristics transition high-speed photography. influence current waveform pressure quantitatively analyzed with different parameters. under conditions are further studi...

Offshore building construction is inseparable from the fabrication process. Fabrication process that has an important role in terms of engineering, material repair and welding In offshore construction, a precise method needed on A36, where A36 steel one main materials buildings. this study comparison results GTAW, GMAW, FCAW against Tensile Test Macrostructure Test. The research show best tensi...
