Abstract

The influence of pulse parameters on the properties of P-GMA welds of ferrous and non ferrous metals which qualifies them for various applications under the static and dynamic loading has been discussed. Control of pulse parameters affecting the various properties is addressed in terms of the factor ϕ. The hardness and tensile properties of weld joints are categorically addressed for the weld deposit and HAZ relevantly with respect to their chemistry and microstructure . The effect of pulse parameters on the properties such as toughness, fatigue, fracture mechanics and corrosion that dictate the safety and durability of weld joint in service has also been relevantly discussed in reference to the weld geometry , chemistry, microstructure and fracture behavior.
