		abstract={Welded joints are metallurgical bonds in metal alloy carried out in a liquid
or semi-liquid state. In its application, the selection of the welding process can be
determined based on consideration of quality improvement. This study aims to
investigate the strength and microstructure analysis on the low carbon plate AISI
1006.
The welding process in this research is SMAW (Shielded Metal Arc
Welding) using current variations of 75 A, 80 A, 85 A and using E6013 electrodes
with a diameter of 2,6 mm with and without cooling treatment. Tests carried out
in this research are tensile strength test and microstructure analysis both in the
welded area and HAZ.
The results showed that the highest average tensile strength was obtained at
80 A current variation by perlakuan cooling treatment with a value of 332.602
MPa, while the lowest average tensile strength was obtained at 80 A current
variation without perlakuan cooling treatment with a value of 243,467 MPa. The
tensile strength of the raw material is 373,037 MPa. Microstructure of the
material both with and without perlakuan cooling treatment showed that the HAZ
changes in size with the form of pearlite and ferrite solid fractions, while in the
welded area, the microstructure changes in size with the form of columns
(pillars).}
