Comparative Study of Welding Material Elasticity with the SMAW Process for 2G Positions Between Before and After Using Welding Machines with Augmented Reality Technology

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 size 1,44 mm (accepted by ASME Section V), whereas it cannot be accepted criteria. maximum open discontinuity length bending on welded specimen 2,90 IX), not citeria. were 410,00 455,66 N/mm2 stress. This value exceeds minimum strength SA-36 carbon steel, which 400 N/mm2. When compared machine, modulus elasticity also smaller, indicating material has elasticity. Based tests, can seen implementation competency because quality weld better, there fewer risks (sparks, eye irritation, burns), consumables reduced
