Effect of metal inert gas welding parameters on the hardness and bending strength of carbon steel plates
AK Jassim, DC Ali, AH Laken - AIP Conference Proceedings, 2021 - pubs.aip.org
A study of the metal inert gas welding MIG process was carried out in order to evaluate the
influence of welding parameters on the hardness and bending strength of welded carbon
steel plates. Welds were made by MIG welding machine using different parameters that
include welding current of 10-200 A, arc voltage of 11-26.5 V, wire welding speed of 1.5-
16.5 m/min and CO2 flow rate as inert gas of 5-25 l/min. The result demonstrations that the
hardness increases with decreasing wire welding speed and increasing welding current …
