In this study, Submerged Arc Welding (SAW) and Gas Metal (GMAW) processes were used in multi-pass welding of 33 mm thickness super duplex stainless steel plates. Recommended higher than recommended arc energy interpass temperatures used. Both GMAW SAW able to produce large weldments meeting the microstructural, mechanical, corrosion resistance requirements, also when using temperature. It was p...

In this work, the thin wall components of TC4 titanium alloy were produced by using external magnetic field hybrid gas metal welding (EM-GMAW). The effect on forming, microstructure, and property wire arc additively manufactured was studied in detail. results showed that height average deposition layer EM-GMAW less than GMAW decreased with increase excitation current, width greater GMAW. micros...

The use of variants the gas metal arc welding (GMAW) process has become an affordable option in industry. Alternating current–gas (AC-GMAW) arises as one them, providing additional degrees freedom for controllability and versatility. This study focused on analysis a complex waveform AC-GMAW stainless steel, employed modern synergic programs, which not been widely disseminated technical literatu...

OBJECTIVES Ultraviolet radiation (UVR) emitted during arc welding frequently causes keratoconjunctivitis and erythema in the workplace. The degree of hazard from UVR exposure depends on the welding method and conditions. Therefore, it is important to identify the UVR levels present under various conditions. METHODS We experimentally evaluated the UVR levels emitted in gas metal arc welding (G...

The dynamic characteristics of droplet transfer are extremely complicated with the combined effects gravity force and weaving motion during vertical-up welding on thick plate. In this paper, we firstly observed behavior under various parameters high-speed photography electrical signals pulsed gas metal arc (P-GMAW). Then, investigated influences different shape molten pool as well characteristi...

In this paper, the parameter optimization of hybrid-tandem gas metal arc welding (GMAW) process was studied. The GMAW uses an additional filler-wire with opposite polarity in contrast to conventional tandem process. process, more parameters and relationship between causing strong nonlinearity should be considered. analysis variance-based Gaussian regression (ANOVA-GPR) method implemented constr...

Gas Metal arc Welding (GMABQ has become the most addely used process for joining of steel plates due to its high productixity, simplicity of equipment and ease of use. Although the process of melting of the electrode and development of the weld deposit has been studied for 40 years, the dynamic nature of the process has not been studied in detail because accurate models are computationally inte...
