Abstract

This study aims to determine the effect of variations of the current with combining two welding techniques SMAW and FCAW in double v-groove against the hardness and microstructure of the dissimilar material of JIS G3101-SS400 and ASTM A36. JIS G3101 SS400 and ASTM A36 each with a thickness of 10 mm were used as the materials. The combination of SMAW welding with E7018 electrodes and FCAW with E71T-1 were used as the welding techniques. The current used in SMAW welding were 60 A, 75 A, and 90 A. While in FCAW welding the current used were 190 A, 205 A, and 220 A. Hardness and microstructure tests were carried out on each sample. The results of the study showed that the current in welding process affect the hardness value and microstructure of material. The higher the welding current, the value of hardness of the material going to decrease and vice versa. The highest hardness values in SMAW and FCAW welding are at currents of 60 A and 190 A. Then the current in the welding process also affect the microstructure produced in the weld and HAZ. The formed microstructure containing pearlite and ferrite. The higher welding current, the percentage of pearlite produced increase and the percentage of ferrite decrease.

Abstract

Welding is a metal joining process with filler or without filler. The welding method is also used to thicken the surface of the material or hardfacing. Hardfacing is a welding process with the aim of improving mechanical properties and is used on worn components by using SMAW welding, SMAW welding is used because it is relatively inexpensive and flexible. The purpose of this study was to determine the effect of hardfacing with SMAW welding direction variations on the tensile strength and microstructure of ASTM A36 steel material. The welding directions are horizontal, vertical and diagonal. This study used ASTM A 36 steel with a thickness of 5 mm. The welding electrode was E7018 with a diameter of 3.2 mm and a current of 130 A. After conducting this research, the highest average tensile strength value was found in the vertical direction, which was 474.74 N/mm2. The average value of the tensile strength in the diagonal direction is 446.715 N/mm2. The average horizontal tensile strength value is 420.785 N/mm2.
