Abstract EN
Twin-Wire Pulsed Tandem Gas Metal Arc Welding process with high welding production efficiency was used to join the girth weld seam of API X80 steel linepipe of 18.4 mm wall thickness and 1422 mm diameter.
The macrostructure, microstructure, hardness, and electrochemical corrosion behavior of welded joints were studied.
Effects of temperature and Cl− concentration on the corrosion behavior of base metal and weld metal were investigated.
Results show that the welded joint has good morphology, mechanical properties, and corrosion resistance.
The corrosion resistance of both the base metal and the weld metal decreases with increasing temperature or Cl− concentration.
In the solution with high Cl− concentration, the base metal and weld metal are more susceptible to pitting.
The corrosion resistance of the weld metal is slightly lower than that of the base metal.
