Abstract

In the SMAW welding process, defects in the weld results often occur caused by residual stresses contained in the area around the weld, defects in is an important welding parameter because it can affect the tensile strength and bending strength of the material, this research aims to determine other strengths tensile and bending strength when welding SMAW with and without reheating reheating. In this research, the SMAW welding method was used E7016 type electrode with a diameter of 2.5 mm with a heating time variation of 1 20 second rounds, 2 40 second rounds and 3 60 second rounds, Materials used in this study is a sign plate with a carbon content of less than 0.3% which is included in the low carbon steel group, and testing uses tests tensile test using ASTM E8M, and bending test using ASTM E190, from research which has been reheated can increase the tensile stress, tension yields even if not significantly, and reduces distortion and has the potential to increase bending strength.
