Analysis of quality control weld cladding at cladtek bi-metal manufacturing

Abstract

The demand for piping companies depends on the development of oil and gas industry projects. PT Cladtek BIMetal Manufacturing is engaged in the manufacturing industry for various jobs concerning metal materials, specifically the weld overlay process such as Cladding on carbon steel pipes for industrial use. The quality of steel pipe products in the past four months is low, as indicated by the presence of several types of defects. The low quality of steel pipe products (defects) resulted in a decrease in production the following month. The purpose of this study was to analyze the quality control of steel pipe products in steel pipe products in the weld overlay process to meet PT Cladtek BI-Metal Manufacturing's client quality standards. Data analysis is done by using variable control maps and attribute control maps. The analysis of the factors causing high repair using fishbone diagrams. Based on the results of processing the data above it is known that the types of defects that are beyond the control limits are the type of defect Poor Profile, Cluster Porosity, Low Clad, Linear. This shows that during the weld overlay process it still does not pay attention to the company's quality standards. The factors that cause the incompatibility of the production process are human, machine, work method, and material. Based on these conditions, the company should be able to make a commitment to support the implementation of quality control in the weld overlay process so that employees can work with loyalty and care during the process. So that it can have an impact on increasing the productivity of employees who work in the welding overlay process.
