Introduction

Definition of welding

Welding is one of the manufacturing processes by which two or more similar or dissimilar materials can be joined permanently by coalescence formation with or without the applications of external pressure, heat or filler material. Read detail…

Advantages and disadvantages of welding joint

Pros of welded joints: permanent joint, superior strength, leak-proof, no drilling, high load carrying capacity, possibility to alter properties, lighter assemblies, dissimilar metal joining. Cons of welding joints: distortion, HAZ, residual stress, poor vibration sustaining capability. Read more…


Autogenous Welding – Examples, Advantages and Disadvantages

What is autogenous welding? By definition autogenous welding is one way of performing fusion welding without the application of external filler material. – Examples, advantages and disadvantages are also provided here. Read more…


Homogeneous Welding – Examples, Advantages and Disadvantages

What is homogeneous welding? Homogeneous welding is one way of performing fusion welding with the application of external filler material whose metallurgical composition is almost same with that of the base metals. Examples, advantages and disadvantages are also provided here. Read more…


Heterogeneous Welding – Examples, Advantages and Disadvantages

What is heterogeneous welding? Heterogeneous welding is one way of performing fusion welding with the application of external filler whose metallurgical composition is substantially different from that of the base metals. Examples, advantages and disadvantages are also provided here. Read more…


Difference between homogeneous and heterogeneous welding

Although external filler material is used in both the cases, in homogeneous welding metallurgical composition of external filler material is almost same with that of the base metals; while in heterogeneous welding metallurgical composition of external filler material substantially different from that of the base metals. Read all differences…


Fusion Welding – Examples, Advantages and Disadvantages

What is fusion welding? Fusion welding processes are all those welding processes where faying surfaces of parent part as well as filler material melt down during welding for weld bead formation. Examples, advantages and disadvantages are also provided here. Read more…


Solid-State Welding – Examples, Advantages and Disadvantages

What is solid-state welding? In all those welding processes where melting of faying surfaces of parent materials don’t take place are called solid-state welding. Examples, advantages and disadvantages are also provided here. Read more…


Difference between fusion welding and solid-state welding

Although both provide permanent joints, in fusion welding processes faying surfaces of parent part as well as filler material melt down during welding for weld bead formation; while in solid-state welding melting of faying surfaces of parent materials don’t take place. Read all differences…
