Abstract

The abstract should summarize the contents of the paper and should contain at least 70 and at most 200 words. It should be set in 9-point font size, justified and should have a hanging indent of 2-centimenter. There should be a space before of 12-point and after of 30-point.This study discusses the effect of welding position on the quality of welded joints using AWS E 7018 electrode. Research was designed in two stages, using the tensile test and the bending test. The result of tensile test shows the comparison of average yield strength of vertical welding position equal to 24,30 kgf/mm2, while horizontal position 22,98 kgf/mm2 and for overhead position is 24,14 kgf/mm2. For the ultimate strength in the vertical welding position is 26.06 kgf/mm2, while for the horizontal welding position is 27.93 kgf/mm2 and for overhead welding position is 22.24 kgf / mm2. Bending test can clearly be seen the comparison of strength and durability of the material used and the position of welding used. In bending test for vertical welding position has bending strength value of 4039,67 kgf, while in horizontal welding position is 4298 kgf and for overhead welding position is 3965,33 kgf. Although in the research results obtained the value of vertical welding position better than the position of horizontal welding and overhead welding position, but other welding positions are also feasible to use depending on the needs of welders and conditions in the field.
