Abstract:
This article examines how AISI 1020 low carbon steel's microstructure and hardness value are affected by ultrasonic waves. in SMAW welding with a seam angle of 60ᴼ using an E7018 electrode with water cooling media and varying immersion time by adding ultrasonic waves. It was found that the hardness value increased with increasing soaking time. Meanwhile, in terms of microstructure, it was found that the longer the soaking time, the more ferrite and pearlite grains were formed. This is due to the influence of carbon filler and heat transfer to the welded steel and the welded steel area.
