Abstract

This paper describes the effect of pulse frequency on the properties of microhardness, porosity and macrostructure in GTAW welding. This study used alluminum 6061 as a base metal and without filler metal. Pulse frequency is varied from 0 Hz to 10 Hz. The macrostructure results showed the maximum penetration depth occured at pulse frequency 6 Hz, while the maximum penetration width occured when did not pulse frequency. Micro hardness testing showed that the maximum hardness occured at pulse frequency 6 Hz while the lowest hardness occured at pulse frequency 10 Hz. AA 6061 welding without metal filler produced porosity which can have an impact on the hardness of the weld metal.

Abstract

Energi memiliki peranan penting dalam perkembangan pertumbuhan ekonomi dan pertumbuhan industri baik jangka panjang maupun jangka pendek. Dengan tingkat pertumbuhan ekonomi 5,02% dan tingkat pertumbuhan penduduk 1,79% tiap tahun di Provinsi Kepulauan Riau, perlu direncanakan dengan baik strategi pemenuhan energi. Pada penelitian ini akan dikaji tentang sumber energi dan kebutuhan energi di Provinsi Kepulauan Riau. Selain itu dilakukan pemodelan menggunakan LEAP untuk memprediksi kebutuhan energi hingga tahun 2025 di Provinsi Kepulauan Riau. Dari hasil penelitian didapat kebutuhan energi Kepulauan Riau didominasi oleh kebutuh Natural Gas sebesar 53% dari total 1,73 Mtoe pada tahun 2015 dan sektor pengguna paling besar adalah sektor rumah tangga dan industri. Selain itu dari hasil proyeksi penggunaan energi, tahun 2025 energi paling besar di konsumsi adalah Natural gas sebesar 0,98 Mtoe dari total 2,4 Mtoe dan sektor pengguna paling besar adalah sektor industri. Produksi Natural gas dan minyak bumi provinsi kepulauan riau menurun tiap tahunnya sehingga perlu dilakukan diversifikasi energi untuk pemenuhan kebutuhan energi di Provinsi Kepulauan Riau.

Abstract

Polishing have played an important role in the preparation of metallography testing. Poor polishing produce in an unflat and rough surface of the material, resulting an unclear metallography image that is difficult to identified. In general, the material commonly used for polishing is alumina paste. Alumina paste is expensive and takes a few minutes to produce a smooth and flat surface. In this research, polishing was done by using several metal polisher other than alumina paste, these were magic***, auto***, bras**, ki*, menze*** and pri** which are sold cheaply at supermarkets or online stores. Analysis was carried out on the surface of the polishing by these materials and the etching surface. The test results showed that the material that is polished with magic *** has the smoothest surface or has the least residual scratches compared to other materials even compared to alumina paste, but has the disadvantage of corrosion forming on some parts of the surface. The best polishing time was obtained on polishing for 3 minutes

Abstract

This research aims to develop a Procedure Qualification Record (PQR) for Repair Through Thickness on S355 KT0 material using the GTAW method for the root, SAW for filler and capping. The welds were repaired using gouging and grinding before undergoing repair welding with the SMAW method. The study employed experimental methods with Non-Destructive and Destructive tests following AWS D1.1 and Client Specification MHK-COMP-SPE standards. The test results indicate defect-free welds that meet AWS D1.1 standards in terms of mechanical properties such as tensile strength, bending, impact, and hardness. The tensile strength values reached 609 MPa (longitudinal specimen) and 539 MPa and 540 MPa for transverse specimens. The lowest impact test value was 139J in the fusion line +2 mm repair to original welds area. The peak hardness test value was 240 VHN in the HAZ (repair to original weld) region. The test results were also used to formulate a PQR that aligns with specific requirements. This research is expected to provide guidance for performing repair welding on S355 KT0 material.
