Abstract

This study aims to determine the effect of electrode motion on the mechanical properties and microstructure of SMAW welding with E 6013 electrode. The SMAW welding process uses a variety of straight, zigzag and spiral electrode movements. The electrode used is E 6013 with a diameter of 3.2 mm. The current size used is 90 Amperes. The type of camp used is a V-shaped with an angle of 60o, a root height of 2 mm and a root range of 3 mm. Tests conducted are tensile testing, hardness and microstructure observation. The highest tensile strength value in the spiral electrode motion is 616.6 Mpa and the lowest in the zig-zag electrode is 596 MPa. While the highest strain value found in the motion of zig-zag electrode is 22.91% and the lowest in the spiral electrode movement is 19.41%. For the highest modulus of elasticity is found in the straight electrode movement of 12070.02 Mpa and the lowest in the motion of the zigzag electrode is 10339,48 Mpa. The highest hardness value is in welding with zigzagging electrode movement that is 147,44 kg / mm2 and the lowest in straight electrode movement is 143,19 kg / mm2

Abstract

Malapoga wood is one of the endemic wood that grows in tropical regions like in Central Sulawesi Province. The purpose of this research is to find out tensile strength and press malapoga wood which is soaked with condensation water. The result of tensile strength test and the compressive strength of malapoga wood with the variation of immersion happened the increase of tensile strength and compressive strength along with the duration of immersion. The longer the immersion time the value of tensile strength and compressive strength increases. The highest value of tensile strength and compressive strength is on soaking for 10 weeks with a tensile strength value of 59,520 MPa and its compressive strength is 29,775 MPa. While the value of tensile strength and the lowest pressure is on the specimen without immersion (raw material) with a tensile strength of 56.040 MPa and a compressive strength of 24.985MPa. Increased tensile strength of 5.84% and an increase in compressive strength of 16.08% of raw material.
