-Hardfacing is one of the most useful and economic ways to improve the performance of components submitted to severe wear conditions. A study was made to compare the microstructure and abrasion resistance of hardfacing alloys reinforced with primary chromium carbides, the hardfacing alloys were deposited onto M.S. plate by SMAW process. Two different commercial hardfacing electrodes were employ...

Welding fume contains elements that, in their pure forms, can be hazardous to worker health if inhaled or ingested. Therefore, the chemical composition of welding fume must be examined when considering fume toxicity. Various chemical analysis techniques are presented and their applicability to airborne particles is described. Knowledge of particle size is important because a given characterizat...

Shielded Metal Arc Welding is a liquid welding process (fusion welding) that produces heat from an electric arc between the electrode and workpiece. The depth of fusion formed determined by input, angle direction. research was conducted in Mechanical Engineering laboratory Padang Institute Technology. test material used low carbon steel 10 mm thick, 100 long wide. carried out on surface work as...

The combination of GTAW (Gas Tungsten Arc Welding) and SMAW (Shield Metal processes on SA537 Class 2 carbon steel using variations heat input is the main choice to get best quality welded joints. This research aims joint material process with determine results mechanical properties microstructure analysis. experimental method uses a single V butt design, groove angle 60o, root face mm gap 4 as ...

stress relieving is a common practice among manufacturing codes for reducing the magnitude ofresidual stresses in welded, quenched, and tempered steel structures and pressure vessels. the presentwork investigates the effect of stress relieving at 480, 560, 620, and 680°c on the microstructure andmechanical properties of 20 mm astm a517 gr. b steel plate weldments produced by shielded metal arcw...
