Metal gas reactions in gas-shielded arc welding
Welding International, 1988Abstract Mixed gas-shielded arc welding is becoming more and more popular. The influences of the gas components on arc and material transfer are known to a considerable extent. There is as yet no general quantitative description of the chemical behaviour of the gases dependent on the composition of the gas shield in arc welding.

Metal transfer instability in gas metal arc welding
Science and Technology of Welding and Joining, 2009This work presents a simplified model of metal transfer in gas metal arc welding. The model incorporates key features of metal transfer including the change in droplet diameters as welding moves from the globular into the spray metal transfer region, and the increase in welding voltage that is observed to occur as the pendant droplet grows.

Feedback linearization based arc length control for gas metal arc welding
Proceedings of the 2005, American Control Conference, 2005., 2005In this paper a feedback linearization based arc length controller for gas metal arc welding (GMAW) is described. A nonlinear model describing the dynamic arc length is transformed into a system where nonlinearities can be cancelled by a nonlinear state feedback control part, and thus, leaving only a linear system to be controlled by linear state ...

Stability of droplets in gas metal arc welding
Science and Technology of Welding and Joining, 2000A method is developed to compute the stability of droplets detaching from the consumable electrode in gas metal arc welding. An aluminium electrode is used as the model system. Theoretical predictions and supporting experiments are used to ascertain the rate of transfer of droplets for a range of current encompassing globular and spray transfer, and ...
