![]() ![]() Majority (about 80%) of the industries use only visual inspection to ascertain the quality of welded products. About ninety percent (90%) of the industries practice manual welding with little automated or robotic welding systems and much welded fabrications still relies on manual metal arc (MMA) welding. The study revealed the different proportions of different industry groups and areas of application of welding activities. Two hundred (200) out of the two hundred and fifty (250) selected firms, representing 80% responded to the inquiry. Designed inquiry forms or questionnaires were administered to the selected welding industries. Two hundred and fifty (250) welding industries across the regions of Ghana both in the formal and informal sectors were selected for the study. ![]() The project covers the categories of welding and welding techniques, welding quality control methods, welding process type used and general challenges that hamper welding productivity in Ghana. This paper discusses the current welding processes and investigates welding practices in some selected metal welding industries in Ghana. In the last several decades, welding has evolved as an interdisciplinary activity requiring synthesis of knowledge from various disciplines and incorporating the most advanced tools of various basic and applied sciences. Welding is essentially a repair, maintenance, manufacturing and constructional engineering activity. ![]()
