Pengujian Tarik Pada Baja Karbon Sedang Di Las Smaw Dengan Pemanasan Suhu 900oc Di Quenching Air Kelapa Dan Udara

Abstract

From the result of tensile test research on carbon steel plate. After the welding process and treated with a load of 3000 kg get the average calculation value are non treatment ?y = 54,32 kgf/mm², ?u = 28,36 kgf/mm² and ?f = 23,78 kgf/mm². The average value of the tensile test on air quenching are ?y = 29,63 kgf/mm², ?u = 34,93 kgf/mm², ?f = 33,01 kgf/mm². The average value of the tensile test on coconut water quenching are ?y = 22,66 kgf/mm², ?u = 29,47 kgf/mm², ?f = 26,79 kgf/mm². this tensile test research, it can be concluded that coconut water quenching , has better result than air quenching.
