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
9、and in agreement with the steel supplier, define characteristics such as mechanical properties, testing direction, formability, surface texture, oiling, thickness to demonstrate acceptable weldability as part of the source approval process: The material supplier shall consistently produce spot welds
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
19、nical property histograms including mean and standard deviation values. Data should consist of a minimum of 40 measurements for each property in para 3.5, taken from a minimum of 20 coils, while the process is operating in statistical control.
