Characterization of a welded joint in steel API.5L.X70 having undergone successive repairs

The second contribution of the above-mentioned complex integration comes from a cut starting at the origin, a cut which we have to chose in the lower half-plane (see [8], A III .4).

It is presented an experimental study on micro milling aluminum alloy with different width of cut in order to identity the influence of the minimum chip thickness on the

The analysis of the diffraction pattern profiles by the Rietveld refinement method (X-ray Diffraction Line Profile Analysis XRDLPA), allows obtaining detailed information on

Abstract : The object of this paper is to study the effect of the successive repairs on the weldment quality, knowing that these repairs constitute a main problem in the

The results show that the succession of repairs in the same area has a direct influence on the microstructure morphology for all the welded joints samples when the mechanical

Four conditions of shielded metal arcwelding repairs and one aswelded specimen of the girth weld were characterized to determine changes in the microstructure, grain size

Abstract : The effect of successive repairs on the weldment quality of API 5L X-70 pipeline steel H.S.L.A. Keywords : welding, Heat affected zone, Thermal cycles,

The obtained values of the tensile strength of the various welded pipes are acceptable by the standards which imply the qualification of the welding process for all the
