Pengaruh Kedalaman Alur Back Chipping Pada Pengelasan Listrik SMAW Baja Karbon Sedang AISI 1045 Terhadap Uji Kekuatan Tarik
Abstract: Medium carbon steel
can be assembled in various ways, one of them by welding. On the implementation
of welding using SMAW welding type which is one method of welding is used
widely in construction grafting techniques. In welding, there’s common defects
such as imperfections of root penetration, hardened and cracked. Back chipping
or welding opponent needs to be done to avoid or fix things that often occur in
the root weld. SMAW welding is one method which is widely used in construction
grafting techniques. This study aims to determine the different test results
with the depth of groove weld seam treatment chipping back to the tensile
strength test also to determine micro structure. The depth of groove seam using
a variation of 2 mm, 3 mm and 4 mm, then the welding results of each treatment
were divided into three tensile test specimens and one photo micro specimen.
Upon completion of the test specimens and then tensile test performed and photo
micro to acknlowledge changes in mechanical properties. From the testing that
has been done, the result from tensile strength at back chipping welding with
3mm depth is higher than treated back chipping welding with 2mm and 4 mm depth.
The largest maximum tensile strength were found in the back chipping welding
groove with 3mm depth is 683.3 MPa, while the untreated back chipping weld the
largest maximum tensile strength is 591.7 MPa. Microstructure of root steel
welding was welded without back chipping has dominant ferrite grain area.
