The goal of Metal Joining Laboratory in Metallurgical and Material Engineering Department of IIT Roorkee is to promote the advancement of quality welding in the industry and to teach welding in UG, PG and PhD level. The Metal Joining Laboratory provides an excellent educational environment where students learn the latest techniques for shielded metal arc welding (SMAW), metal inert gas welding (GMAW) , submerged arc welding (SAW), and tungsten inert gas welding (GTAW).

Equipments

ESAB Welding Power Source

A, ESAB make Aristo 2000 – LUD 450 UW model, direct current (D.C) welding power source along with a MEK 44C wire feeder was employed in the present investigation. The power source is capable to operate for different welding processes such as SMAW,GTAW, GMAW and P-GMAW in both the synergic and non-synergic modes at a given command regarding the material and diameter of electrode/filler wire as well as shielding gas.

Lincoln Powerwave 455M/Powerfeed

10M LINCOLN ELECTRIC CO. USA inverter based synergic pulse MIG/MAG welding power wave 455 machine. The power feed 10M single feeder is well suited for all MIG welding processes, giving premium arc performance especially with unusual alloys and out of position work. The power wave is capable to operate for different welding processes such as SMAW, GTAW(Touch Start TIG only), GMAW, P-GMAW and FCAW in both the synergic and non-synergic modes.
