Today, the quality of welded seams is often examined off-line with either destructive or non-destructive testing. These test procedures are time-consuming and therefore costly. This especially true if welds not accurately due to process anomalies. In manual welding, experienced welders able detect anomalies by listening sound welding process. this paper, an approach transfer “hearing” welder in...

The high cost of certification and the low pass percentage in welding are common issues for beginner welders. use Augmented Reality (AR) technology is expected to solve these issues. results penetrant, bending, tensile tests showed that welder who had used AR machine produced better specimens than before they practiced using machine. penetrant test after produces rounded defects with a defect s...

Duplex stainless steels (DSSs) find increasing use as a substitution to austenitic in oil, gas and petrochemical industries, particularly aggressive environments. with appropriate controlled ferrite-austenite balance combine the attractive properties of excellent strength, general corrosion performance adequate weldability. All welding joints subjected regulation must be before commissioning pi...

Teknik pengelasan semakin banyak dipergunakan secara luas dalam proses penyambungan plat-plat besi, kontruksi bangunan dan konstruksi mesin. Salah satu metode yang sering dipakai, yaitu gas metal arc welding (GMAW). Tujuan penelitian ini adalah untuk mengetahui parameter terbaik pada Pengelasan GMAW terhadap struktur mikro, makro kekerasan Material ASTM A537 A653 DDS (galvanis). Metode digunaka...

Special attention in is paid vocational (and technical) colleges, today's realities remain leading establi...

The friction stir welding (FSW) is widely used in the fabrication of Aluminium alloy and other non-ferrous alloy. It has good potential to be major industries such as automobiles, aerospace, shipbuilding can joining high strength alloys. FSW process low distortion heat affected zone (HAZ) with fine recrystallized microstructure which leads better mechanical properties at weld produces great sta...
