Abstract :
This study was conducted in order to examine
the effect of the welding current and the gas pressure of
argon on the welded joints' characteristics, especially the
bending properties. Welding using the Tungsten inert
gas (TIG) is conducted on 304-stainless-steel sheets based
on the probable values of currents and welding gas
pressures. Accordingly, the impact of both parameters
on the max bending force (MBF) value of the welded
joints by TIG was understood. Using the Design of the
experiment (Version.10) denoted by (DOE), the
experiment's design matrix was determined based on the
input factors values. Also, a mathematical and empirical
model was attained based on a technique known as
Response-Surface-Methodology (RSM). The proposed
model dealt with the effect of the prementioned welding
parameters on the welded zone’s MBF value, in which
the parameters are the gas pressure and the current
values. Finally, verification of the model adequacy was
performed using ANOVA, which is the analysis of
variance.
