4、fined by these specifications are spot weldable, heat curing, heat expanding sealers. 2. APPLICATION WSK-M4G325-A1/A3: These specifications were released originally for dimensioned materials used for sealing spot weld joints on the body-in-white. It is applied to oiled surfaces in the form of self a

5、dhesive strips. WSK-M4G325-A2/A6: This specification was released originally for non-dimensioned materials used for sealing spot weld joints on the body-in-white. It is applied to oiled surfaces by an extrusion apparatus. WSK-M4G325-A4/A5: These specifications were released originally for non-dimens

6、ioned materials used for sealing joints in BIW. It is applied to oiled surfaces by an extrusion apparatus. The materials are applicable on oiled surfaces with acceptable oil film weights (European applications limit the oil/pre-lubricant film weight to max 3 g/m, see para. 3.7). Note: Care must be t

7、aken to ensure that the local oil film weight in the area of the adhesive/sealer application does not exceed the critical limit. Monitoring of the film thickness, adequate storage of the part and/or cleaning of the surface prior to sealer/adhesive application is necessary to avoid critical film thic

8、kness values, which would then cause malfunction of the sealer/adhesive. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when this specification is listed on the drawing, CAD

9、file, or other documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. Material specification requirements are to be used for initial qualification of materials. ENGINEERING MATERIAL SPECIFICATION WSK-M4G325-A1/A2/A3/A5 WSS-M4G325
