    Extensive advancement in the field of the joining science has led to the development of a wide range of joining processes and techniques. Welding is one of the most widely used joining processes. Various standards have been developed to regularise welding processes and ensure manufacturing consistency. However, there are many inconsistencies and incoherencies in terms of process categorisation within and across the welding standards. It is imperative to undertake investigations on the limitations and issues of the current welding standards in semantic inconsistency, and then to reveal the inadequacy of text based definitions of welding concepts. To address the issues, in this paper, core domain ontology for joining processes (CDOJP), that can semantically categorise joining processes to reconcile semantic inconsistency, is developed. An ontological approach using Web Ontology Language (OWL) is used to define the ontology. The generic nature of the proposed ontology allows it
    to be applicable to various joining processes. The proposed ontology is further consolidated to the welding standards so that semantic inconsistencies in the standards can be effectively resolved. This research is validated in an industrial environment via collaboration with one of the largest aero engine manufacturing companies. The recommendations from this research are useful for the international standards committees to improve the joining and welding standards.
