a short gist of the main presentation......

1. Points to be included in the
presentation (WELDING)
•Overview of joining methods
•Basic process & concepts - electric arc, arc energy, arc
length, arc voltage, etc.
• Types of Materials Handled
•Welding processes- fusion welding , solid phase, etc.
•Basic requirements of welding processes -
(weldage preparation cuts, consumables [procurement,
inspection, etc.], types of electrodes like E6010, E6011, E7024,
etc.)
•Fusion welding heat sources- electric resistance, chemical
reaction, electric arc, power
beams.
•Solid phase welding- Hot (forge,friction,etc.) , Cold
(ultrasonic,explosive,etc.)

2. • Some arc welding processes -MMAW, SAW, GTAW, GMAW, FCAW.
• Description of the above mentioned processes includes-
Features, equipment, consumables, applications.
• Comparison between arc welding techniques.
• Recent developments- Plasma cutting & welding & surfacing, Thermit,
Laser, Electron beam, Resistance welding, Flash
butt, Friction, Explosive, etc.
• Broad comparison of all the welding techniques with respect to cost and
material thickness and finish.
• Allied processes - Thermal cutting, gouging, Surfacing, typical coating
constituents.
