Welding Welding provides a means of building up an assembly by joining together plates, bars, pipes and other standard sections.

Welding The process is also useful in cases where castings, forgings and pre-machined parts have to be fabricated into a main assembly.
Welded fabrications are usually cheaper than castings for small batch or one-off jobs because the need for expensive patterns does not arise.
