TYPES OF WELDING

this presentation provides you the knowledge releated to basic components and working of various types of welding which is known by every mechanical engineer hope you like....

1. TRANSLAM INSTITUTE OF TECHNOLOGY & MANAGEMENT SEMINAR ON- WELDING SUBMITTED TO - SUBMITTED BY- PROFF. MUKESH SIROHI ISHANT GAUTAM B.TECH (M.E)- IVth year

2. WELDING Welding is a material joining process which produces coalescence of materials by heating them to suitable temperatures with or without the application of pressure or by the application of pressure alone and with or without the use of filler material. Welding is used for making permanent joints.

3. CLASSIFICATION OF WELDING

4. ARC WELDING Equipments A welding generator (D.C) or transformer (A.C). Two cables one for work and one for electrode. Electrode holder Electrode Protective shield Gloves Wire brush Chipping hammer Goggeles .

5. Arc welding

6. ADVANTAGES & LIMITATIONS OF ARC WELDING Advantage Most efficient way to join metals. Lowest cost joining method. Join all commercial metals. Provides design flexibility. Affords lighter weight. Limitation Manually applied therefore high labor cost. Need high energy causing danger. Defect s are hard to detect at joints.

7. RESISTANCE WELDING Resistance welding is a welding technology widely used in manufacturing industry for joining metal sheet & components. Seam welding Spot welding Projection welding Upset welding Flash welding

8. Resistance welding

9. Resistance welding

10. GAS WELDING Sound weld by selecting proper size of flame filler material and method of moving torch. The material generated during the process is 3300 C Fluxes are added to the welded metal to remove oxides Flux can be applied as paste , powder ,liquid. Solid coating or gas

11. Gas welding

12. Gas welding equipment Gas cylinder pressure oxygen-125Kg/cm2 acetylene-16kg/cm2 Regulators working pressure of oxygen 1kg/cm2 working pressure of acetylene 0.15 kg/cm2 3. Pressure gauge 4. Hoses 5. Welding torch 6. Check valve 7.Non return valve.

13. Welding process is used joint materials.
