This study investigates the effect of increased welding layers welded by SMAW process on distorsion, thickness, microstructure, hardness, and corrosion. The method used in this research is experimental. Low-carbon steel with a size 150x10x10 mm was technique using an HV 450 electrode. Variations are single, double, triple. three variations samples were observed digital camera optical microscope...

Analisis “Pengaruh Variasi Kuat Arus Pengelasan Terhadap Berat Deposit Las Per Milimeter Pada Test Ring ASTM A694 GR F65 Dan Pipa DNVGL SMLS 450 SFPDU MOD Menggunakan Proses SMAW Di Pt. Mcdermott Indonesia – Batam”. Digunakan sebagai penyambung di bagian pipa yang digunakan mengalirkan fluida. Tujuan penelitian ini adalah untuk mengetahui pengaruh kuat arus terhadap berat deposit las per milime...

Welding is an activity of joining two or more metals by heating them until they melt, in which the melted workpieces will unite with help additional materials to form a connection whole piece metal. The purpose this study was determine effect welding current, type electrode and pattern movement on strength welds against impact test order produce optimal strength. method used Taguchi Method. Thi...

In this study, the effect of cladded tungsten carbide layer upon HSS - M2 tool steel on microstructure, hardness, and wear behavior has been studied in two cases without using the middle layer and using the middle layer of nickel. Tungsten Carbide cladded on HSS - M2 tool steel by Arc Weld ( SMAW ). The ASTM-G65 wear test was used to determine its application for use in the mineral indus...

The objective of this research is to develop an experimental-theoretical analysis about the influence of the cooling medium and the geometry of the welding bead profile in fatigue life and the associated parameters with structural integrity of welded joints. A welded joint with cruciform geometry is considered using SMAW (Shielded Metal ArcWelding), plates in structural steel ASTM A36 HR of 8 m...

This study aimed to analyze BKI Grade (KI-A) plate material using the pre-heat process determine tensile strength and hardness. The method involved welding with shielded metal arc (SMAW) type. variations used several temperatures, such as 50⁰C, 120⁰C, 220⁰C, without heat treatment. obtained specimen pre-heating had lowest of 442.64 MPa, 220⁰C highest average 450.11 MPa. result showed that was p...
