• During the Bronze age, metals were used for

domestic tools, weapons etc. � but more

complex shapes cannot be built in one piece.

• The first development of forge welding by the

Syrians (1400 BC).

• Welding was then increasingly utilised in

response to military requirements for example,

riveting of suits of armour.

• A commercial scale for bolting, riveting,

soldering and finally welding was introduced.

History of joining techniques

Tapany Udomphol

Introduction to metal joiningIntroduction to metal joining• Metal joining is required whenever the desired

component cannot be made by means of simple

fabrication processes such as casting, forging,

rolling, extrusion, etc.

• Metal joining is indispensable to manufacturing

industry because it is necessary in large

constructions, components required for modern

living.

However, knowledge of welding

are poorly understood, which

reflects in the quality of the weld.
