Welding : Production

Welding or Metal Joining Process :

Joining Process :

In mechanical bending , stength of the joint is less than combined strength of the original member .

Classification of Joining Process :

1. Autogenous : - no filler material is added during joining .

2. Homogeneous : - filler material is used same as parent material .

3. Heterogeneous : - filler material is used different from parent material .

Welding : 

Welding is the process of joining two or more similar or dissimilar metals -

(A) with or without the application of heat .

(B) with or without the application of pressure .

(C) with or without the application of filler material .

Type of welding :

1. Pressure or Non fusion welding

2. Fusion welding 

2. Fusion welding :

1. Gas welding :

                             1. Oxy - acetylene welding

                             2. Air - acetylene welding

                             3. Oxy - hydrogen welding

                             4. Oxy - LPG Process

2. Arc welding : 

     1. Gas shielding Arc welding

           (A) tungsten inter - gas welding (TIG)

           ( B) Metal inter gas welding ( MIG ) 

        2. Plasma Arc weldin

        3. Electric Arc welding 

3. Arc Blow :
