Substitution of Expensive Welding Electrode from Japan With Domestic Electrode to be Applied in Continuous Galvanizing Line Machine

Abstract

Nowadays, efficiency improvement is a main necessity. Continuous Galvanizing Line is a machine that produces galvanized iron sheet using continuous hot dip galvanizing as the coating process. A welding machine is equipped tojoin the strip of coil andmake sure the process in Continuous Galvanizing Line machine runs continuously. The welding machine use Japan made welding electrode that is very expensive andhave a long lead time. The purpose ofthis research is to develop a domestic welding electrode to substitute Japan made welding electrode and resolve its weakness. The domestic welding electrode developed is an alloy that made of98.9% ofCu, l%ofCr and 0.1% ofZr elements. The domestic welding electrode has a good welding quality to substitute the original Japan made welding electrode and reduce the cost of the welding electrode fromRp. 110.000.000 to Rp. 7.000.000.
