Proses penyambungan (welding) cerobong pada industri manufaktur menengah kebawah memiliki kesulitan karena banyaknya variasi ukuran dari cerobong. Target waktu penyelesaian sulit dicapai karena keterbatasan alat bantu (Fixture) yang dimilikinya. Maka dari itu, perlu dirancang alat bantu yang dapat m
Welding process of chimney on medium size manufacturing industries encounters some problems because of the large variations in the size of the chimney. Target of completion time is difficult to achieve due to tool (Fixture) limitation. Therefore, it is necessary to design a tool that can reduce the obstacles at an affordable cost. The design of this tool is done through the application of the VDI 2222 method with the help of CAD CAM technology. Several alternative designs have been produced through the design process. Selected design was modeled and validated using Solidworks software. Some of the parameters that affect the function of the fixture includes deflection, torsional load and center of gravity. The results of the analysis of deflection at maximum load is 2.406 mm, while the twisting loads that occur is 119 N or approximately equivalent to 12 kg of weight received by the operator. Center of gravity of the fixture is 1,492.3 mm from the rear wheels with 1,600 mm wheels distance, so it is safe from the possibility of tumbling. Apart from the aspect of construction, speed is the other important factor affecting the production process. Based on the results from the comparisons with an existing tool used in one company in Bandung, the estimated of the new design has a 269 minute faster for 4 chimney welding process with 1,500 mm long with a diameter of 900 mm. Based on the construction and analysis study, it can be concluded that the welding fixture can be used for connecting the chimney, especially small and medium sized manufacturing companies.
