5、e Year Review and update of this specification. 1. SCOPE 1.1 Form This specification covers an aluminum alloy in the form of two types of welding wire. 1.2 Application This wire has been used typically as filler metal for gas-metal-arc and gas-tungsten-arc welding of aluminum alloy castings having s
6、imilar composition (206.0 and A206.0) and requiring response to heat treatment, properties, and corrosion resistance in the weld zone comparable to those of the castings, but usage is not limited to such applications. 1.3 Classification Wire supplied to this specification is classified as follows: T
7、ype 1 - As Extruded and Sized Type 2 - As Drawn 1.3.1 Unless a specific type is ordered, either type may be supplied. 2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The suppli
8、er may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply.
