PENGARUH DIAMETER ELEKTRODA TERHADAP PENETRASI PENGELASAN SMAW ARUS DC PADA BAJA KARBON RENDAH ASTM A36 MENGGUNAKAN SISTEM SLIDING ADAPTIVE TWO AXIS

SMAW welding is a method of joining metals from several electrode rods using heat
energy. Several welding parameters affect the welding results including the amount
of current and electrical polarity, welding speed, electrode, welding position, and
seam. This research discusses the effect of electrode diameter variation on SMAW
welding penetration using direct polarity current. Electrode diameter variations of
2.5 mm and 3.2 mm and currents of 80, 90, and 100 A. The material used is ASTM
A36 steel plate thickness of 3 mm and 5 mm. Test were conducted visually,
penetrant, and metallographically. The results of this study show that electrode
diameter, current, and plate thickness affect the characteristics of welding results.
Electrode diameter of 2.5 mm, current of 80 and 90 A produced good welding
quality and weld penetration on 3 mm plate. On a 5 mm plate, an electrode diameter
of 3.2 mm and a current of 100 A produces optimal welding and better penetration.
The larger electrode diameter affects the growth of the number and size of pearlite
grains and the HAZ area but does not change the type of phase formed. The test
results can be used as a reference in industrial practice to improve the efficiency
and quality of welding results.
