Optimization of Source-Wire-Gas Systems for Efficient Robot Welding [PDF]
International Journal for Simulation and Multidisciplinary Design Optimization, 2010 GMAW (Gas-Metal-Arc-Welding) as the last of main technologies, yet based for a most part on manual (semiautomatic) work, is gradually automated. But traditional advances of weld design, technology and quality assurance is not essentially changing.
