Abstract

Welding is an important process in manufacturing sector and FKP’s students are required to learn and perform robotic and manual welding. In performing this welding process, student who is lack of welding experience will encounter difficulties such as bent workpiece and causing damage to worktable. The technicians also have to setup new coordinate system every time the robotic welding laboratory is to be conducted. In order to addressing these problems, design and fabrication of welding jig and fixture for manual and robotic welding for lab usage become a solution. The design concepts based on prior learning of other researchers and survey data collected from technicians and students who have taken subject on welding based on House of Quality approach. Three conceptual designs were done using CAD system. The final design was selected among four conceptual designs based on screening and scoring methods with assistance from experts. The final design was fabricated using aluminium. Once the fixture was fabricated, another survey was performed to seek feedback from the customer on the effectiveness of the fabricated the welding fixture. As the results, respondents said that the fixture can improve learning process, improve weld quality, reduce heat distortions and time consumptions and suitable used during lab session.
