Joining Processes

• Manufacturing of a part as a single unit is not always possible. The part may be produced in the form of different components and these components need to be joined to get the complete assembly of the part using several joining processes.
• Important joining processes include welding, soldering, brazing, adhesive bonding and mechanical fastening.
• Welding produces the strongest joint in metals and is permanent in nature. A welded part needs to be broken to dismantle it. Welding uses heat and the use of pressure is optional.
• Soldering and brazing produce weaker joints in low melting point metals and alloys.
• Adhesive bonding is used to join metals, non-metals, plastics and composites using adhesives. It is semi-permanent ...
