To make the butt joint using the two given metal strips.

To make the butt joint using the two given metal strips.

1. Experiment no 3
Objective:
To make the butt joint using the two given metal strips.
TOOLS REQUIRED:
AC transformer, Hand shield, holder, apron, gloves, wire brush, chipping
hammer, electrode, Flat file.
SEQUENCE OF OPERATIONS:
1. Checking
2. Edge preparation
3. Work piece positioning
4. Electrode positioning
5. Welding


PROCEDURE:
1. The given work piece is checked first its dimensions.
2. The edge preparation is done to the work piece in such a way that the root is 1.6 X 1.6.3.
3. The work piece is placed horizontally in such a way that the length is place down the table.
4. The welding rod is held in the electrode holder and the ground clamp is clamped to the plate.
5. The torch is held in right hand side and the welding rod is in left hand side.
6. The plates to be welded are positioned touching each other and tag weld is done on the ends to
avoid the movement of the plates during welding.
7. The electric arc produced melts the welding rod and joins the two metal plates.
8. Complete the welding process by removing slag using chipping hammer.

RESULT:
Thus the job is welded in horizontal position by arc welding
