THE DEVELOPMENT OF MAGNETIC HOLDER FOR MARINE GRADE STEEL PLATE WELDING

Abstract

This thesis is regarding the final year project for diploma student in University Kuala Lumpur Malaysian Institute of Marine Engineering Technology (UnikL-MIMET). The title is development of magnetic holder for marine grade steel plate welding . The student needs to design and fabricate a magnetic clamp for welding process. The magnetic clamp must low in cost of production and doesn’t give damage to the workpiece. It is to overcome the problem that arise such as the current magnetic clamp are expensive and the other clamp such as table clamp and portable clamp can give damage to the workpiece. The student needs to use various fabrication processes in the making of this project. All the skill had been taught in previous workshop in MIMET. Firstly, the work must be plan well so the work can be finished in time. A Gantt chart is constructed in order to show the date and time for the specific work to be done. Moreover, a flow chart is also constructed to visualize the step-by-step process of making this project. Literature review is done early to give better understanding about what is magnetic clamp. Then the student makes the sketches of the magnetic clamp. All the sketches undergo screening process and only 3 that pass the screening. The 3 sketches are then refined before final concept is selected using scoring process. The final concept is then turned into 3D drawing. The 3D drawings are generated using computer software. After the detail of the drawing is finished, the project is fabricated. Starting from the measuring and marking process until the assembly process is done using the tools and equipment in the workshop. The machine such as milling machine, lathe machine and drilling machine are used to fabricate this project. Lastly the project is tested to make sure the magnetic clamp can function well. The project has work successfully.
