Journal TeknomekanikTeknomekanik Abstract

The aim of this study is to determine the effect of variations in welding current strength on the tensile strength of ABREX 400 steel weld joints. The results of this study are expected to contribute to the world of metal welding, especially low carbon steel metal welding, which will later be beneficial for the development of the metal industry and technology. The method used in this research was the experimental method. In addition, the process of welding the material used SMAW welding and the type of seam V connection and the variations in the current strength used are 90 A, 100 A, and 110 A. The specimen used was a TRS 400 low carbon steel plate with a thickness of 10 mm and the electrode used was the E7018 electrode Ø 3.2 mm. The standard specimen used was ASTM-8 and the test was carried out using the Universal Testing Machine tensile test device. As a result, the research showed that the tensile strength at a current of 90 A was 588.91 N / mm2, a current of 100 A was 570.56 N / mm2, and a current of 100 A was 545.17 N / mm2. Based on the results of the research, it can be concluded that welding using a current strength of 90 A produces the highest tensile strength value, namely 588.91 N / mm2 compared to currents of 100 A and 110 A.

Conclusion

Based on the data analysis and discussion, it can be concluded that welding current strength affects the strength of the ABREX 400 steel.The specimen broke in the weld area, indicating a potential mismatch between the electrode and the steel or a defect in the welding process.The highest tensile strength was achieved at a welding current of 90 A, with an average value of 588.

Future Research

Penelitian lebih lanjut dapat dilakukan dengan memvariasikan jenis elektroda yang digunakan dalam pengelasan ABREX 400 untuk mengidentifikasi kombinasi elektroda dan arus yang menghasilkan kekuatan tarik optimal. Selain itu, studi mendalam mengenai pengaruh teknik pengelasan yang berbeda, seperti teknik weaving atau stringer bead, terhadap kualitas sambungan las dan kekuatan tarik juga perlu dilakukan. Terakhir, penelitian yang berfokus pada analisis metalurgi mikrostruktur sambungan las dengan variasi arus dan jenis elektroda dapat memberikan pemahaman yang lebih komprehensif mengenai mekanisme kerusakan dan potensi peningkatan kekuatan tarik pada material ABREX 400, sehingga dapat menghasilkan rekomendasi pengelasan yang lebih akurat dan efisien untuk aplikasi industri.
