Relationship of weld-metal microstructure and penetration to weld-metal oxygen content
Journal of Materials for Energy Systems, 1983The weld-metal oxygen content has been found definitely to influence the behavior of the welding process. Flux composition can alter the weld-metal composition, affecting weld-bead morphology, microstructure, and mechanical properties. Further research is necessary to understand the actual means by which oxygen and other weld-metal residuals influence ...

The Characteristics of Weld Metal Zone Welded with Various Filler Metals
Advanced Materials Research, 2013Recently, the fuel oil of diesel engines of marine ships is being changed to heavy oil of low quality as the oil price is getting higher and higher. Therefore, the wear and corrosion in all parts of the engine, such as cylinder liner, piston crown, and spindle and seat ring of exhaust valves has predominantly increased.

Characteristics Evaluation of Weld Metal Zone Welded with Various Repair Welding Filler Metals
Advanced Materials Research, 2013Recently, the fuel oil of diesel engine of marine ships has been changed with heavy oil of low quality as the oil price is getting higher and higher. Therefore, the wear and corrosion against all parts of the engine, such as cylinder liner, piston crown, and spindle and seat ring of exhaust valves has predominantly increased due to its consumption ...

Effects of Welding Current on Metal Transfer and Weld Pool Dynamics in Gas Metal Arc Welding
Heat Transfer, Volume 2, 2006In gas metal arc welding (GMAW), current is one of the most important factors affecting the mode of metal transfer and subsequently the weld quality. Recently, a new technology using pulsed currents has been employed to achieve the one droplet per pulse (ODPP) metal transfer mode with the advantages of low average currents, a stable and controllable ...

Ultrasonic Welding of Refractory Metals
1961Abstract : The effect of input power, clamping force, and duration of welding interval on the tensile-shear strength of ultrasonic welds in 0.005-in. Mo-0.5% Ti alloy sheet were studied and the results are tabulated. Exploratory tensile- shear measurements were made in 0.010-in.
