Abstract


The development of modern manufacturing industry technology era is increasingly rapid. In the era of modern technology when welding is a manufacturing process that is widely used with various types of materials that are increasingly diverse. This study aims to determine the hardness value and strength level of welding on different materials. The materials used in this study are S45C steel and galvanized steel A653 using Gas Metal Arc Welding technology, with different welding current variations, the current variations used are 75A, 100A, 125A, and 150A. From the results of compressive tests that have been carried out, the highest strength value of the 125A current variation with an average value of 12.42 kg/mm2, the second highest value with a variation of 100A current with an average value of 10.80 kg/mm2, the third rank with a variation of 75A current with an average value of 8.83 kg/mm2, while at the lowest value with a variation of 150A current with an average strength value of 7.26 kg/mm2 and the results of hardness tests that have been carried out on welding metal, steel and galvanized steel there is a significant difference. This is due to the influence of current variations carried out during the welding process, the greater the current strength given does not make the welding have strength, the greater the current given will cause damage to the material. Although the hardness test results show fairly high hardness value. However, the area around the welding has a fairly low level of hardness
