Abstract

OPTIMIZATION OF TUNGSTEN INERT GAS WELDING PROCESS FOR A36 LOW CARBON STEEL ON TOUGHNESS ENGINEERING PROPERTY

Chukwuedo Joses Azuka*, And Emifoniye Elvis, Oyibo Alfred Onakemu

ABSTRACT

Joining of A 36 grade steel with the process of welding can be a tasking with accompanying problems of cracking, and mechanical properties change of welded joing compared to the parent material. This is due to limited knowledge on parametric welding balance to obtaining efficient joint. The quality of welded joints depends primarily on the type of welding and the parametric value range chosen. The mechanical properties of impact strength on the welded joint using Tungsten inert gas welding process on A36 grade low carbon steel was studied with varied current, voltage and gas flow rate. The Box bekhken method of design on response surface method was used in the design of experiment that gave a total of (17) runs. Conclusively, Welding parameter of current 117A, Voltage 16V and gas flow rate resulted in a toughness value of 27Joules.
