| Summary: | Joining dissimilar metals has recently become very popular in industries because of the advantages associated with the weld joint. This paper focuses on an investigation of mechanical and material properties, and the optimization of mechanical properties in resistance spot welding methods
in lap configurations between AISI 301 stainless steel
and AISI 1020 carbon steel.The Taguchi method was used
to design experiments. Welding was conducted using a spot welder. Tensile and Charpy impact test specimens
were
prepared
from
the welded
sheets
in appropriate dimensions
and
tensile and
Charpy
impact
test
s
were performed
for
each specimen. The
depth and width of weld nuggets
were investig
ated.
It can be concluded from the investigation that the welding joint in
this method can offer moderate strength and moderate
Charpy
impact energy.
From the
results of the Taguchi analysis, the combination of optimum parameters for dissimilar
stainless s
teel
-
carbon
steel
resistance spot welding
is
:
welding
current
,
5.0kA
;
welding
squeeze time
,
3.0 cycle
;
and welding pressure
,
40 psi.
In order to
improve
significant
mechanical and metallurgical
properties of the joint, o
ther variable parameters like
voltag
e, electrode
tip
diameter
etc
.
can
also
be
introduced and
investigated
so that
the
most influential parameters
and their suitable ranges
can be
identified
