Abstract

Welding is a procedure of changeless joining two materials (normally metals) through confined mixture coming about because of an appropriate blend of temperature, weight and metallurgical conditions. Contingent on the mix of temperature and weight from a high temperature with no weight to a high weight with low temperature, a wide scope of welding forms has been created. There are numerous kinds of welding including Metal Arc, Submerged Arc, Resistance Butt, Flash, Spot, Seam and Projection. While there are numerous techniques for joining metals, welding is a standout amongst the most helpful and fast strategies 1available. The gas metal circular segment welding (GMAW) process utilizes a strong wire terminal that is ceaselessly bolstered into the weld pool. The wire anode is devoured and turns into the filler metal. GMAW hardware is moderately low in expense. The low starting cost, the capacity to weld constantly, and the capacity to store weld metal quicker, settle on GMAW an alluring decision for welding. This chapter reveals every aspect of GMAW. It comprises all components of GMAW such as welding machine, shielding gases, filler/electrode wire and welding joint assembly of welding plates. V grooved butt joint will be filled with 1.6 mm electrode wire ( ER 90 BL-3) using ESAB AUTO K 400 welding machine. Specimen for various tests such as hardness, tensile, micro-structure, inclusion and gas absorption will be drawn from the butt welded joint as per specification.
