This paper aims at the development of an advanced control technology for pulsed gas metal arc welding (GMAW) of titanium or other materials which require a highly stable metal transfer process. It is known that conventional pulsed GMAW achieves stable and repeatable spray transfer by using correct pulse parameters. Because the optimal pulse parameters depend on welding parameters such as wire f...

Abstract Take the wear parts of coupler knuckle as an example, “Modeling—Slicing — Stacking” mode remanufacturing process is studied. First, 3D model worn surface acquired by structured light detection. The failure part built Boolean operation between original and model. Second, user can slice layer according to stacking parameters. zone that surrounded contour each sliced robotic GMAW stack re...
