Abstract

This investigation examines the used parameters in the wet welding process, as well as his influence on the properties of welded union under manual metal arc welding process, obtained at 10m and 20m sea water deep, with an electrode E7024. The E7024 filler material is normally used in the reparation of hydrocarbon pipelines on deeps no more of 30m, however his chemical composition allow to use as material to repair in zones where the pressure is a paramount factor. A statistical design of experiments (DOE) with 36 coupons has been proposed using the travel speed, amperage and the underwater welding condition (10m and 20m) as input variables. To evaluate the quality of the welded unions, tensile, bend, hardness and metallographic test were carried out. The statistical analysis of DOE found that the amperage variable result to be the most influence parameter in the control of quality of the weld union. Besides this the technique of scanning electron microscopic was used to observe the kind of fractography showed in a crack throughout weld resulted from the bend test, and energy dispersive X-ray spectrometry to identify the present species in this zone.
