The definition of Transition Joint

A Transition Joint is a specialized mechanical or metallurgical component used to join two dissimilar materials—typically metals—that cannot be easily welded or bonded together by conventional means.

Common Characteristics:

Purpose: Enables the connection of metals with different physical or chemical properties (e.g., aluminum to steel, copper to stainless steel).

Design: Usually consists of layers or sections of each material, joined using explosion welding, friction welding, brazing, or other solid-state bonding techniques.

Applications: Widely used in industries such as:

Aerospace

Shipbuilding

Cryogenics

Power generation

Chemical processing

Example:

A transition joint might be used to connect an aluminum pipeline to a steel structure, ensuring both strength and corrosion resistance while compensating for the different thermal expansion rates of the two metals.
