Evaluation of Corrosion Résistance for Austenitic Stainless Steel Weldment in Different Solution
Engineering and Technology Journal,
2012, Volume 30, Issue 17, Pages 369-381
AbstractThis paper is amid to study the effect of immersion solusion type on corrosion
resistance of austenitic stainless steel AISI 304L .
The process welding carried out on sheet metal by using four types of
electrodes (E308L,E309L,E312,E347) to obtain butt joint welding under constant
conditions polarity(DCSP) , voltage(30)v, current (120)A .
Welding speed (100) mm/min and two weld passes by using electrode of
diameter 3 mm.
Many specimens for corrosion test were manufactured in (20*20*8) mm from
welding joint stainless steel.
Corrosion test was implemented by using weight loss, specimens were
immersed in two solution (1% H2SO4) Sulphric Acid and (3.5%Nacl) sea water for
(1-30 ) days and corrosion rate was measured.
The results show that sulphric acid was more effected on stainless steel.
