Abstract: Controlled quasikeyhole plasma arc welding process adjusts the amperage of the peak current to establish a keyhole in a desired time. This keyhole establishment time is the major parameter that controls the consistence of ...

Abstract: Plasma arc welding (PAW) has several advantages over traditional gas tungsten arc welding (GTAW) process. However, due to its sensitivity to welding parameters, this process has not been widely used in industry, especially ...

Abstract: Doubleelectrode submerged arc welding (DESAW) is a new variant of the innovative doubleelectrode gas metal arc welding (DEGMAW) process. In order to control this process, its dynamic model needs to be established. To this ...

Abstract: A system has been developed to measure the threedimensional weld pool surface geometry in the gas metal arc welding (GMAW) process. It utilizes the specular nature of the weld pool surface by projecting a fiveline laser ...

Abstract: Understanding and modeling of the human welder's response to threedimensional (3D) weld pool surface may help develop next generation intelligent welding machines and train welders faster. In this paper, human welder's ...

Abstract: Welding is a major manufacturing process that joins two or more pieces of materials together through heating/mixing them followed by cooling/solidification. The goal of welding manufacturing is to join materials together ...
