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.

GMAW WELDING

GMAW ( Gas Metal Arc Welding) or MIG ( Metal Inert Gas Welding ) or MAG ( Metal Active Gas welding )  is the one of the arc welding types. In GMAW process shielding gas is used instead of electrode flux. this presentation will explain about this process.

Arc welding Consumables

This presentation explain the different types of consumables used in arc welding.

GAS WELDING

This presentation explain about gas welding process, equipment used in the gas welding, types of flames produced during welding, reason to the flames, advantage and disadvantage of each flame.

Regions in fusion weld zone

Regions in fusion weld zone are explained in the presentation.

TYPES OF WELDING ARC & ARC INITIANTION METHODS

Types of the welding arc and arc initiation methods used in the welding processes are explained in this presentation.

WELDING ARC PHYSICS

SMAW VARIENTS

SMAW - Shielded Metal Arc Welding process is the one of the basic arc welding process. This presentation will explain varients of the SMAW process and advantages, disadvantages of the each process.

Joining of magnetic materials

Ferro magnetic materials (iron, nickel, cobalt)  are considered as magnetic materials. Magnetism and its types, reason for magnetism, problems encountered during welding in magnetic materials, remedies for the problems are explained in the below presentation.

SOLDERING

  Soldering is a process in which two or more items (usually metal) are joined together by melting and putting a filler metal (solder) into the joint, the filler metal having a lower melting point (below 450°C) than the adjoining metal. Soldering differs from welding in that soldering does not involve melting the work pieces.
