DIFFERENT TYPES OF ELECTRIC WELDING

Arc welding    a) Inert Gas Shielded

                        b) Slag Shielded

Inert Gas Shielded                                                         Slag Shielded

 i)  Non-consumable Electrode                                      1) Flux cored process

            1) Plasma arc                                                       2) Shielded Metal Arc 

            2) Carbon arc                                                       3) Submerged arc

            3) Atomic hydrogen                                             4) Stud welding

            4) T.I.G. (argon shielded)

  ii)  Consumable Electrode 

         1) M.I.G. (Argon shielded)

a) Pulse Transfer

                b) Spray Transfer

           2) M.I.G. (CO2 Shielded)

              a) Spray Transfer

                 b) Dip Transfer 

           3)  Flux cored process 

ARC WELDING: -                           Inert Gas      or    Slag

INERT GAS :-           Non consumable Electrodes         Consumable Electrodes

NON CONSUMABLE TYPE :=      Plasma   /    Carbon Di-oxide  /  Argon (T I G)

Consumable Electrodes   :-   MIG(argon) / MIG(CO2) / Flux Coated

SLAG   :--  Flux coated / Shrouded  metal ARC / Submerged arc / stud welding

Faults :-  

Lack of  root penetration 

Undercut

Blow holes

Overlap

Side fusion

Slag inclusion

Minimum penetration
