Fusion Welding Process

Fusion welding is the category of welding process where, by some means, enough heat is generated to locally melt the adjacent areas of the joining members. Sometimes, this welding process involves using of the filler materials. The joining members must have similar metallurgical properties and melting points to produce a strong joint. Theoretically welded joints are said to be stronger than parent materials. The properties like ductility, fatigue strength and tensile strength get decorated at the heat affected zone.

Advantages:

–      Variety of materials can be chosen

–      Variety of welding design can be chosen

Disadvantages:

–      The materials of the heat affected zone become brittle

–      Not suitable for reactive materials

Ideal applications: Can be applied for joints where the change in material property of the welding heat affected zone is acceptable.
