JOINABILITY
In conjunction with the material supplier and Product Development Materials Engineering, the affected local manufacturing activity shall, as part of the initial material source approval process, approve the joinability (e.g., resistance spot welding, riveting, adhesive bonding) of this material by means of laboratory test(s), manufacturing trial(s), and/or another mutually acceptable alternative, using the e and methods that are proposed for production.
If needed to enable the fabrication of a specific component, restricted tolerances and/or additional material property re (i.e., the " level" of the steel) shall be developed by the affected manufacturing activity and the steel supplier. Examples include, but are not limited to: restricted chemical composition, restricted gauge tolerance, specified minimum n-value, and specified surface condition.
The " level" of the steel for a specific component:
· shall not conflict with specified re in paragraph 3 of this Engineering Material Specification
· shall be described in detail by the local manufacturing activity
· shall be a mandatory extension of these Engineering Material Specifications
Acceptance of subsequent orders by the steel supplier for a given component at the agreed upon level implies that all steel supplied will be of a comparable level and can be joined satisfactorily as defined and recorded by the manufacturing activity.
3.7 SURFACE APPEARANCE, CONDITION, AND SURFACE ROUGHNESS (Ra)
3.7.1 Surface Classification
Surface appearance shall be defined as Class 1 or Class 3:
· A Class 1 surface shall be specified for parts of the vehicle that are exposed to view after paint or trim.
