A Survery of Possible Welding Defects in Steel Sheets Caused by Shielding Gases in GMAW and Laser Welding

Lasline – gases for laser welding and brazing

Minimizing distortion caused by welding, by sequencing optimization in a large steel panel

Increasingly, Welding is used in industry for assembled various products, such as ships, cars, trains and bridges. Welding distortion often results such as lack of accuracy during assembly and will have increases manufacturing costs. So, predict and reduce welding distortion is very important to improve the quality of welded structures.  In this study, firstly, a prediction method of welding di...

Microstructure and mechanical properties of similar and dissimilar welding joints of weathering steel and plain carbon steel by GMAW with CO2 shielding gas

The welding joints were investigated due to the significance of similar welding of Corten A weathering steel and its dissimilar welding with St12 plain carbon steel in industrial applications. The gas metal arc welding (GMAW) technique with carbon dioxide shielding gas was utilized in the present work. The welding process comprised current and voltage control, welding wire injection rate, shiel...
