Welding quality and sustainability of alternative LPG valve boss welding processes [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2019 This work aimed to evaluate the welding quality and the sustainability of an automatic metal active gas with mixing gases (MAG-M) process for welding the valve boss on liquefied petroleum gas (LPG) upper cylinder half, in comparison to the presently ...

Effect of Flux in Submerged Arc Welding- A Review [PDF]
, 2017 Submerged arc fluxes play a very complex role during the welding process. Besides protecting the weld pool and influencing the bead geometry, fluxes also melt in a specific temperature range, refine the weld metal, as well as take part in slag metal ...

Process Stability, Microstructure and Mechanical Properties of Underwater Submerged-Arc Welded Steel
Metals, 2021 In underwater wet welding, the unstable welding process caused by the generation and rupture of bubbles and the chilling effect of water on the welding area result in low quality of welded joints, which makes it difficult to meet the practical ...
