The emission of dusts and gases, which are generated during tubular cored wire welding and which are hazardous to health and the environment, were studied. Tests included various kinds of tubular electrode wires used for welding steel, that is, rutile flux cored wires, basic flux cored wires, and metal cored wires for welding unalloyed, low-alloy, and high-alloy steels as well as self-shielded ...

Pengelasan adalah proses penyambungan logam atau non-logam yang dilakukan dengan memanaskan material akan disambung hingga temperatur las, tanpa menggunakan tekanan dan pengisi. Salah satu teknik pengelasan SMAW (Shield Metal Arc Welding) GTAW (Gas Tungsen Welding). Dengan las tersebut kita dapat menyambung seperti: Aluminium, Tembaga, Carbon Steel, Stainless Steel. Penelitian ini untuk mengeta...

Industrial technology programs around the country must be sensitive to the demands of manufacturing and industry as they continue to replace “vocational” curriculum with high-tech alternatives. This article examines whether or not teaching oxyacetylene welding in the industrial technology classroom is required to learn arc welding processes. The results of this study suggests that there appears...

Welding is an area in which technological developments out match the developments in its science base, which is primarily driven by the phenomenal industrial demand for welded structure. Reliability, Reproducibility and Viability requirements are forcing Technologists to look at weld defects such as distortion, hot cracking, in a systematic and logical approach than on adhoc basis. Distortion i...

ASTM A36 is the most used type of mild steel especially in construction and manufacturing industry. Welding process regularly employed to fix crack that usually occurs low carbon after a long time use In this study, effects heat treatment on mechanical properties [ASTM A36] lap welded joint were investigated. Seven pieces 60 mm × 300 bar for research. Five samples treated an electric muffle fur...

Austempered ductile iron (ADI) is a new engineering material type which continue receiving increased attention in research and industry. Extensive conducted so far has demonstrated that ADI excellent property combination such as high strength-weight ratio, ductility toughness, good fatigue strength, damping properties wear resistance. As result of to their exceptional mechanical mix, fabricatio...

Welding is a process of joining two or more metals into form connection using heat process. This study aims to determine the value bending test strength on SMAW welding E6013 electrode, variations electric current, namely 100A, 110A, 120A and cooling media. The method used with AISI 1037/ST37 material. type seam V-slope slope 600 according AWS d1.1:2000 standardization. carried out Three Point ...
