WELDING PRACTICAL -6

 

Corner joint

To make a corner joint using the given M.S. pieces and by arc welding, you need to first prepare the pieces by cleaning them and removing any rust or debris. Then, position the pieces at a 90-degree angle and secure them in place with clamps.

Aim:-To make a corner joint using the given M.S.pieces and by arc welding.

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

Raw Material:- Two mild steel pieces of (100*50*2.5mm) and electrode 1.5mm.

Procedure:-

1. Take the two workpieces.

2. The workpieces are positioned on the welding table from a corner joint with the required over-caping.

3. Switch on the power supply.

4. Switch on the power source welding machine.

5. Join the work lead to the –ve terminal.

6. Select the electrode 3mm.

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

8. The arc is struck and the workpieces are welded at the ends of both sides.

9. The alignment of the lap joint is checked and the tack welded pieces are resting if required.

10. The Earth clamp is fixed on the welding table.

11. Welding is then carried out throughout the length of the corner joint.

12. Remove the slag, and spatters, and clean the joint.

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

Safety:-

1. Obey PPE (Personal Protective Equipment).
2. Work as per instructions.
3. Keep yourself away from the fumes.
4. Check the welding cables.
5. Wear proper clothing.
6. Use a hand screen while welding.
7. Check for electric sparks while welding.


Result:- The corner joint is thus mode using the tools and equipment as mentioned above.
