| Summary: | Welding is a complicated process at which each welding process would be different from one another. However, there are some commonly known easier welding processes compared to other processes. A welder that is qualified for a more difficult welding process should be qualified for easier welding processes. Hence, a standardised document, qualification testing of welder for fusion welding (ISO 9606) is made to ease the process of qualifying welders. In ISO 9606-1, fusion welding of steels is covered. Different welding set-up and variables will have a different range of qualification as stated in ISO 9606-1.
The document is seemingly impossible for anyone to memorise and remember as it is too lengthy and complicated. Besides, there will be too troublesome for examiners or any party to produce the certificate of qualification by referring to the lengthy document. Hence, an expert system is needed in this case to ease the process of qualifying welders according to ISO 9606-1. An expert system with all the necessary features and the name of “WellWeld” has been successfully developed by the author. The learning outcomes of this project are essentially useful to the author for future development of similar applications.
