Butt welding is an important link to ensure quality, and the penetration state of weld main criterion achieve this. Online monitoring control welded joints measure quality. The molten pool image monitored by a visual sensor in gas metal arc (GMAW) process, bottom width predicted regression network model. Combined with real-time method, current changed monitor real time. Butt-welding experiments...

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...
