Rancang Bangun Jig dan Meja Sebagai Alat Bantu Proses Spot Welding Presisi pada Material Pelat Strip

Abstract

The development of the furniture industry in Indonesia is experiencing its heyday in recent years. The national furniture and handicraft industry is able to break into the international market through a variety of superior products that are considered to have attractive quality and designs. Products that have high demand in the international arena are chairs. The product in this study has a component, namely a woven plate that needs to go through a spot welding process. To simplify the welding process, it is necessary to have tools, namely jigs and sliding tables in order to save processing time during mass production later. Seeing these problems, tools will be made to support the spot welding process, namely jigs and tables that will be made specifically to adjust the material to be worked on and also adjust to the spot welding specifications contained in the company. Making the concept of jig and table as a tool will use the Ulrich method with stages starting from formulating problems and analyzing needs in the field, followed by making and selecting concepts, then proceeding with analyzing loading calculations. Based on the jig and table trials on spot welding, it produces products with a precision level of distance between product components and an angle precision level between product components above 90%.
