This chapter shall govern the quality, design, fabrication and erection of aluminum.
Aluminum for structural elements shall at all times in the fabricator's plant, be marked, segregated, or otherwise handled so that the separate alloys and tempers are positively identified, and after completion of fabrication shall be marked to identify the alloy and temper. Such markings shall be affixed to completed members and assemblies or to boxed or bundled shipments of multiple units prior to shipment from the fabricator's plant.
Welding operations performed on aluminum used for structural purposes shall comply with the following:
1. Welding work shall be performed only by persons who have obtained a license from the commissioner.
2. Tack welds that are not later incorporated into finished welds carrying calculated stress shall not be considered as structural welds.
3. The inspection of welding operations shall include a check to ascertain that the welders employed on the work have the required license.
As erection progresses, the work shall be securely bolted, or welded, to resist all dead loads, wind, and erection stresses.
The structure shall be properly aligned before riveting, permanent bolting, or welding is performed.
