Effect of process parameters in GMAW

                   In this presentation we see about influence  of process parameters in GMAW weld bead shape and productivity. In this presentation We discuss some influencing parameters. they are

–Welding current
–Electrode size

–Arc voltage

–Arc travel speed

–Electrode extension

–Electrode position

–Welding position

Shielding Gases used in arc welding

        In this presentation we seen about purpose of Shielding Gases used in arc welding and selection of shielding gases based on external parameters like weld metal thickness, penetration depth.
