Abstract

PT. STAR COMGISTIC INDONESIA is a company engaged in household electronics production field that makes 3 types of electronic products namely cooking utensils, electric iron and coffee pot. In the production process must pay attention to the quality at each stage in order to get the best production results optimal. Internship practice shows that the process of making a product that used in the production process must be done carefully and activities according to the existing standard operating procedures (SOP), so that the results of production can be of good quality or the results of production get good results optimal. The internship that was carried out at PT STAR COMGISTIC INDONESIA was on repair molding field. (molding) basically consists of two parts, namely the stationary part of the mold (stationary platen) in which the molten polymer is deposited, and the movable platen on the cover side or ejector side of a injection molding parts.Repair molding is a work in which repairing mold or mold that is damaged or needs maintenance, repair mold is done so that the mold can work properly. After done repair, when the molding is damaged before being repaired then the result production becomes defective or imperfect, for results from before being repaired and after fixing there is already an image in the testing section, for this case it is hoped that the mold can work as before it was damaged so that the product produced from the mold to produce an optimal product.

Abstract

Pressure vessel is a container for a fluid, both liquid fluid and pressurized gas. In designing a pressure vessel, there are several things that must be considered, namely the stress that appears on the vessel wall due to the pressure caused by the fluid in the vessel, the weight of the vessel itself, or due to pressure arising from external factors. The process of making pressure vessels is carried out using the rolling process and the assembly welding process. The welding process must be considered based on the level of density, leakage and at the same strength. Planning the welding procedure to be carried out on the pressure vessel, the first welding process carried out is Head, Shell 1 body, Shell 2 Body, Shell 3 cone, Shell 4 cone, and Bottom Plate. The material to be used is SA 516 GR 70 according to ASME (American Society of Mechanical Engineers) section II D. Welding process using GMAW (Gas Metal Arc Welding), welding connection planning, welding parameters and everything related to the welding process is determined and summarized on WPS (Welding Procedure Specification) based on ASME (American Society of Mechanical Engineers) section IX. Testing on the welding results is carried out in several stages starting from the penetrant test, radiography test, peneumatic test, and hydrostatic test. The test is carried out to determine the quality of the welding results. Then an analysis of the results of the welding that has been tested is carried out to really know the quality of the standardization used. Based on the results of several stages of testing on the GMAW (Gas Metal Arc Welding) welding process with the standardization used, there are still defects in the welding results.
