6、COATING The wire shall be supplied with a copper coating for corrosion protection. No deterioration shall be seen when kept in a moderately dry storage area for a period of not less than 6 months. The weight of the copper coating layer is limited by the total copper weight-% limit given in paragraph

7、 3.3. The coating shall have a good adhesion so as to prevent flaking and clogging of the conduit harness and torch tip. 3.4 SURFACE FINISH AND APPEARANCE Wire furnished to this specification shall have a smooth finish, free from compounds or other materials detrimental to the quality of the welding

8、 and/or the welding equipment. 3.5 WELDING PERFORMANCE This specification is a material specification only and does not cover the application specific performance requirements given in engineering specifications for the welding process, engineering drawings or manufacturing control plans. Performanc

9、e requirements and appropriate validation tests will be agreed and approved by the responsible product design and manufacturing engineering activities. 4. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements ofthis specification. Co
