PROCESS OR CYCLE OF LABOUR
PLASMA WELDING
The flaps of the trunk of cone are joined longitudinally by means of longitudinal welding to plasma, autogenous welding, without the use of filler materials such as wire and flow, with the absence of process residues, and without visible welding, with penetration to 70-80% of the thickness. Welding shall be carried out in accordance with the technical specifications for machining (WPS) in accordance with ISO 15609-2 and using qualified procedures (WPAR) in accordance with ISO 15614-1.
All welding personnel are qualified according to UNI EN 1418 and 287-1 and are supported and supervised by an international Welding Engineer (internationally qualified) supervision. In this respect, the welding shall be subject to visual inspection (VT) carried out by qualified personnel in accordance with EN 473.
