T joint 

To create a T joint using M.S. pieces and arc welding, first, prepare the pieces by cleaning and beveling the edges. Then, position the pieces to form a T shape and clamp them securely

Aim:-To make a T joint using the given M.S.pieces and by arc welding (1 F).

Tools and Equipment:- Welding set, Power supply, Power source, workplace, lead, electrode, electrode–holder, Welding table, earth clamp.steel wire brush, gloves, tong, flat file, scriber, bench vice, steel rule, try square, chipping hammer, goggles.

Raw Material:- Two mild steel pieces (150*50*5mm) and electrode 2.5mm.

Procedure:-

1. Take the two PLAT.

2. The two pieces are positioned on the welding table such that, they are separated slightly for better penetration of the weld.

3. The ground clamp is fastened to the welding table the machine is switched on.

4. The electrode is fitted into the electrode holder and the welding current is set to a proper value.

5. Job tacking, alignment then checks <90 angles.

5. The first run of the weld is done to fill the T joint.

6. Second run of the welding is done with proper weaving and uniform movement during the process of welding the electrode is kept at 15 to 25’ from vertical and in the direction of welding.

7. The slag formation on the weld is removed by a chipping hammer.

8. Filing is done to remove spatters around the weld.

Safety:-

1. PPE.

2. Keep yourself away from the fumes.

3. Check the welding cables.

4. Wear proper clothing.

5. Use a hand screen while welding.

6. Check for electric sparks while welding.
