Metal welding process selection calls for extensive know-how which deals with a huge
amount of knowledge. Hence, the automation of knowledge through a knowledge-based
system will greatly enhance the decision-making process. Fuzzy analytical hierarchy
process (AHP)-TOPSIS investigates the relative welding process selection factors and it can
compare and evaluate different welding processes between 0 and 1. This paper describes a
knowledge-base system developed for identifying the most appropriate welding .
