Key Words: Arc Welding, Electrode formulation, Hardness, Microstructure, Substrate.
Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the work pieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the work pieces to form a bond between them, without melting the work pieces.
PROCEDURE OF EXPERIMENTAL The experiment is divided into two parts:
Part A: Preparing Test Specimen Part B: Testing Test Specimen
Part A: Preparing Test Specimen
To perform arc welding process three specimens were prepared. Specimens were prepared for welding process. All there specimen were joined with three manipulation of welding electrode.
Part B: Testing Test Specimen
The entire welding specimens were tested for welding quality. To know the welding quality two types of tests were performed.
Table 1 below shows the values of hardness at various electrode manipulations. It is observed that circular manipulation achieved maximum hardness.
Table 1: Hardness at different manipulation of electrode
Type of Manipulation
Figure 1 shows the microstructure of welded zone with straight manipulation of electrode. Figure 2 shows the microstructure of welded zone with circular manipulation of electrode. Figure 3 shows the microstructure of welded zone with Zigzag manipulation of electrode.
Figure 2: Straight Manipulation
Figure 3: Circular Manipulation
Figure 4: Zigzag Manipulation
Present work showed microstructure and maximum harness value at different manipulation of electrode. From the result of hardness it is concluded that maximum hardness can be achieved by doing circular manipulation. The micro structure of circular manipulation is smoother and evens that other two manipulation.
