Abstract

Welding is a technique of joining metals by melting part of the parent metal using heat energy, this causes the metal to experience extreme changes in temperature which can result in the metal experiencing corrosion. This research aims to determine the effect of variations in current strength and movement patterns on the corrosion rate of AISI 1037 steel. In this research, AISI 1037 steel was welded using variations in current strength of 80A, 90A and 100A as well as variations in straight, zig-zag and point movement patterns. The results and conclusions of this research are that there is a strong influence of current and movement patterns on the rate of corrosion. The specimen that experienced the highest corrosion rate was specimen 3 with a current variation of 100A and a straight movement pattern. The specimen that experienced the lowest corrosion rate was specimen 7 with variations in current strength of 80A and point movement patterns. The conclusion is that high current strength causes high corrosion rates and different movement patterns cause corrosion because uneven surfaces produce small depressions in the welded specimen.
