SAE AMS 4245C:2003 pdf download Aluminum Alloy, Welding Wire 5.0Si – 1.2Cu – 0.50Mg (355)
1. SCOPE:1.1Form:
This specification covers an aluminum alloy in the form of two types of welding wire.1.2Application:
This wire has been used typically as filler metal for gas-metal-arc and gas-tungsten-arc welding ofaluminum alloy castings having similar composition and requiring, in the weld zone, response toheat treatment, properties, and corrosion resistance comparable to those of the castings, but usageis not limited to such applications.
1.3 Classification:
Wire supplied to this specification is classified as follows:Type 1As Extruded and Sized
Type 2As 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 thisspecification to the extent specified herein. The supplier may work to a subsequent revision of adocument unless a specific document issue is specified. When the referenced document has beencancelled and no superseding document has been specified, the last published issue of that documentshall apply.

3. TECHNICAL REQUIREMENTS:
3.1Wire Composition:
Shall conform to the percentages by weight shown in Table 1, determined in accordance withAMS 2355 or MAM 2355.
3.1.1 Chemical analysis of initial ingot, bar, or rod stock before drawing is acceptable provided the processes used for drawing or rolling, annealing, and cleaning are controlled to ensure continued conformance to composition requirements, and the facility employs procedures to ensure traceability of wire to the originally analyzed source.
3.2 Condition: As drawn or extruded and sized, as ordered. Wire shall be in a temper and with a surface finish which will provide proper feeding of the wire in machine welding equipment.
3.3 Fabrication:
3.3.1 Butt welding is permissible provided both ends to be joined are identified by chemical analysis or the repair is made at the wire processing station. The butt weld shall not interfere with uniform, uninterrupted feeding of the wire in machine welding equipment.
3.3.2 Drawing compounds, oxides, dirt, oil, and other foreign materials shall be removed by cleaning processes which will neither result in pitting nor cause gas absorption by the wire or deposition of substances harmful to welding operations.
