OPTIMASI KUALITAS HASIL PENGELASAN GAS METAL ARC WELDING (GMAW) BAJA ASTM 283 GRADE A DENGAN RSM (RESPONSE SUFRACE METHODOLOGY)
ABSTRACT: This research aimed
at the investigation of the effect of welding current, welding voltage, and
welding speed on the hardness of weldment. The material used in this research
is steel ASTM 283 grade A. An optimization approach is performed in order to
determine the variables combination of the welding current, voltage, welding
and welding speed to maintain the weldment to be below hardness and was closer
with parent metal hardness. With application Response Surface Methodology(RSM)
mathematical relationship between the welding process input parameters and
output variable like hardness of welded joint in order to determine the welding
input parameters that lead to desired weld hardness. RSM design of experiment
techniques can be very efficiently used in the optimization of welding
parameters in GMAW process. Formulation of equation is done with the help of
which hardness can be predicted as Y = 218.624 +10.31 I+1.614V-4.017s-1.723
I2+0.929 s2.
