Abstract:
This research investigates the Hot-wire Gas Tungsten Arc Welding Parameter on the carbon steel welds property. Conducting this experiment, three parameters were considered 175 ampere welding current, 120-180 ampere hot-wire current, 100 mm. per min travel speed. After welding, investigation for mechanical properties by impact test and fracture characteristics. Experimental results showed that hot-wire current 180 ampere produced , the maximum absorption energy. With the ductile fracture. In addition, it appears that decreased of hot-wire current the absorb energy and produced a brittle fracture
