CLASSIFICATION OF WELDING PROCCESS

-There are about 35 different welding processes and several soldering methods in use by industry today.
-There are various ways of classifying the welding and allied processes and may be classified on the basis of:
1) Source of heat,flame,arc etc.
2)Types of interaction i.e liquid/liquid (fusion welding) or solid/solid (solid state welding).
-In general various welding and allied processes are classified as follows.
A) Gas Welding                                  C)Resistance Welding
-Air acetylene welding                         -Spot Welding
-Oxy -acetylene welding                      -Seam Welding
-Oxy - Hydrogen welding                    -Projection Welding
-Pressure Gas welding                         -Resistance Butt Welding
B) Arc welding                                    -Flash Butt Welding
-Carbon arc welding                            -High Frequency Resistance Welding
-Shielded metal Arc Welding                D)Solid State Welding
-Flux Cored Arc Welding                     -Cold Welding
-Subnerged Arc Welding                      -Explosive Welding
-TIG Welding                                       -Friction Welding
-MIG Welding                                      -Roll Welding
-Plasma Arc Welding                            -Diffusion Welding
Electro slag Welding                              -Forge Welding
Electric Gas welding                              -Hot Pressure Welding
-Stud Arc Welding                                -Ultrasonic Welding

E)Thermo-Chemical Welding Processes
