Descriptions
At NY Welding LLC, we are experts in navigating the specific, and sometimes intricate, rules of AWS D1.1 prequalification. While the concept sounds simple, the devil is in the details. The code lays out strict limits on joint geometry, base metal chemistry, filler metal selection, preheat requirements, and other essential variables. Straying outside these limits, even slightly, invalidates the prequalified status and throws you back into the realm of procedure qualification. Our service ensures that your prequalified WPSs are not just forms, but fully compliant, well-documented, and practical procedures that your welders can execute successfully, giving you the speed of prequalification with the confidence of expert validation.

Precision Procedures for Thin-Gauge Steel. Master Sheet Metal Welding with D1.3.
Welding structural sheet steel typically defined as material thicknesses of 3/16 inch (4.8 mm) and less presents a unique set of challenges that are not adequately addressed by the standard structural code, AWS D1.1. The high heat input that is manageable on 1 inch plate will simply vaporize 16 gauge sheet metal, leading to catastrophic burn-through, severe warping, and a weak, compromised joint. The AWS D1.3: Structural Welding Code Sheet Steel exists specifically to govern this delicate work, providing prequalified procedures and acceptance criteria that are sensitive to the realities of thin gauge fabrication.
oint geometries are adapted for thin materials. For example, the code provides for flanged edge welds, which are unique to sheet metal and do not require filler metal.
he prequalified procedures inherently control heat input by specifying parameters suitable for thin sections. This is the primary defense against burn-through and distortion.
The code has specific rules for arc spot welds (plug welds) and fillet welds on sheet steel, with maximum and minimum sizes that are appropriate for the material thickness.
Visual acceptance standards for discontinuities like undercut and porosity are often more lenient in D1.3 than in D1.1, reflecting the different service conditions and stress states typical of sheet steel assemblies.
