Transcript

  • 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.
