Gas-tungsten arc welding of AZ91 magnesium alloy
Journal of Alloys and Compounds, 2011Abstract The gas-tungsten arc (GTA) welding behaviors of the commercial AZ91 magnesium alloy were examined in terms of process efficiencies and microstructure characteristics. This study focused on the effects of GTA welding process parameters (like welding current in the range of 100/300 A and welding speed in the range of 3.33/13.33 mm/s) on energy

Characterization of welding arc and weld pool formation in vacuum gas hollow tungsten arc welding
Journal of Materials Processing Technology, 2013Abstract An experimental method is suggested to obtain the effective arc radii for various welding conditions in vacuum gas hollow tungsten arc welding. The irradiance distribution of welding arc next above the anode workpiece is obtained by applying Abel inversion algorithm to the CCD arc image, and then used to determine the distribution of arc ...

Robust control of gas tungsten arc welding system
Chinese Journal of Mechanical Engineering (English Edition), 2007The robust control law for gas tungsten arc welding dynamic process,which is a typical sampled-data system and full of uncertainties,is presented.By using the Lyapunov second method, the robust control and robust optimal control for a class of sampled-data systems whose underlying continuous-time systems are subjected to structured uncertainties are ...
