Abstract

Variation in geometry of P-GMA weld as a function of pulse parameters has been discussed in order to understand the control of welding process to produce desired weld geometry of required chemistry for an acceptable weld quality. The mechanism of the control of weld geometry governed by its basic aspects as penetration , width, reinforcement, form factor, toe angle and area along with the base metal fusion and dilution has been explained as a function of pulse parameters especially with respect to ϕ and energy input . The matter has been discussed considering the cases of bead on plate weld deposition and weld cladding in flat position using solid filler wire. The cases of bead on plate weld deposition have also been considered for the flux cored filler wire and also for the out of position deposition. The geometrical aspect of weld joint as a function of pulse parameters has been addressed for flat and positional butt welding of ferrous and non ferrous metals.
