Influence of electromagnetic vibration on microstructures and mechanical properties of carbon steel (aisi 1045) on gas tungsten arc welding process

This research aimed to study the influence of Electromagnetic vibrations on the Microstructure and
Mechanical Properties of Carbon Steel (AISI 1045) in a Gas Tungsten Arc Welding Process. The experimental
factors include Electromagnetic pulses (0, 20, and 40 hertz), welding current (120 and 140 amperes), and
Welding speed (100 and 200min/min). The results revealed that the three main factors – vibration, welding
current, and welding speed had a statistically significant effect on the ultimate tensile strength at 0.05. The
microstructure was ferrite and pearlite. The results of tensile strength were that the maximum tensile
strength is 782.58 N/mm2 at Electromagnetic Vibration is 40 hertz, the Welding current is at 120 amperes, and the Welding speed is 100 mm/min. It has a Tensile Strength of 782.58 N/mm2. The lowest Tensile
Strength is 389.73 N/mm2 when Electromagnetic vibration is at 0 hertz, the Welding current is 140 amperes,
and the Welding speed is 200 mm/min.
