Steel cleanliness may involve the use of a mutually agreed referee

8、 method. Acceptance of subsequent orders by the steel supplier for a given component at the agreed upon quality level implies that all steel supplied will be of a comparable quality level and will form that part satisfactorily as defined by the manufacturing activity. The company may, at its option

10、 which never experience any interfacial failure, regardless of the testing method (peel or shear) or the strain rate. The spot welding technique and number of spot welds shall be agreed between the Material Supplier and the relevant company Weld Inspection Activity, prior to the commencement of the

17、el submissions see WSS-M1P94-A) For initial approval, the supplier should furnish the following information for each variant: . A plan detailing how each requirement of para 3 will be controlled on a continuing basis. . Test results from a typical production sample for the requirements outlined in p

18、ara 3, with the exception that paintability testing should be conducted on one sample. . The intent of para 3.7 is that the Material Supplier should assess material that aims towards the highest chemistry and thinnest gauge (i.e. the most difficult material to spot weld) for any given grade. . Mecha
