Scope 1.1 This document gives requirements for qulifiction tests of welding procedures intended for the use of weldble steels s specified in UR W7, UR W8, UR W11 nd UR W16 for hull construction nd mrine structures. 1.2 This document specificlly excludes the welding procedure specified in UR W All new welding procedure qulifiction tests re to be crried out in ccordnce with this document from 1 July This document does not invlidte welding procedure qulifiction tests mde nd ccepted by the Clssifiction Society before 1 July 2007 provided the welding procedure qulifiction tests re considered by the Clssifiction Society to meet the technicl intent of this UR or hve been qulified in ccordnce with the recognized stndrds such s ISO, EN, AWS, JIS or ASME. 2. Generl 2.1 Welding procedure qulifiction tests re intended to verify tht mnufcturer is dequtely qulified to perform welding opertions using prticulr procedure. 2.2 In generl welding procedure tests re to reflect fbriction conditions in respect to welding equipment, inside or outside fbriction, weld preprtion, preheting nd ny postweld het tretment. It is to be the mnufcturer s responsibility to estblish nd document whether procedure is suitble for the prticulr ppliction. 2.3 For the welding procedure pprovl the welding procedure qulifiction test is to be crried out with stisfctory results. Welding procedure specifictions re to refer to the test results chieved during welding procedure qulifiction testing. 2.4 Welding procedures qulified t mnufcturer re vlid for welding in workshops under the sme technicl nd qulity mngement. Note: 1. This UR is to be uniformly implemented by IACS Societies on ships contrcted for construction from 1 Jnury 2007 s well s the mnufcturing of which is commenced on or fter 1 Jnury The contrcted for construction dte mens the dte on which the contrct to build the vessel is signed between the prospective owner nd the shipbuilder.
