The influence of basic vs. rutile electrode on the composition of duplex stainless steel weldments

Abstract
The effects of the type of electrode coating – basic or rutile – on the composition of a welded structure made of duplex stainless steel UNS-S31803 have been investigated. It was found that when welding with an electrode having a basic coating (“basic electrode”) the covering of the slags affords better protection of the melt against the entrapment of air but is less effective in de-oxidizing it. There is, therefore, more dissolved oxygen when welding with a basic electrode, and consequently more ε-Fe2O3 is created. On the other hand, the entrapment of air when a rutile-coated electrode (“rutile electrode”) is used leads to considerable porosity and a higher nitrogen content.
