Covers standard processes like SMAW, GMAW, GTAW, and FCAW.
Welding consumables must match or exceed the minimum tensile and yield strengths of the selected base metals. Designers can verify compliant material combinations using the official resources found through the American Welding Society Store . Base Metal Specification Minimum Yield Strength Compatible Filler Metals (AWS Classification) 36,000 – 50,000 psi E7018, ER70S-6, E71T-1 ASTM A514 100,000 psi E11018-M, ER110S, E110T 4. Workmanship and Fabrication Standards
A weld that passes D1.1 may still fail under the dynamic, reversing loads of a crane. For example, D14.1 has more stringent requirements for impact toughness (Charpy V-notch testing) because a cold crack on a hook is far more dangerous than on a building column.
Before fabrication begins, manufacturers must develop a Welding Procedure Specification (WPS). This document acts as the recipe for a successful weld. AWS D14.1 details how to perform Procedure Qualification Records (PQR) to prove that a specific combination of base metal, filler metal, shielding gas, and welding parameters yields a mechanically sound joint. 3. Performance Qualification (WPQR)
Table 5.2/5.3 in the code gives precise preheat temperatures based on the carbon equivalent (CE) of the rebar. Incorrect preheat leads to brittle, failing welds. aws d141 pdf full

No structural crane weld may be laid without an approved WPS. The AWS D14.1 framework covers standard processes such as: Shielded Metal Arc Welding (SMAW) Gas Metal Arc Welding (GMAW) Flux-Cored Arc Welding (FCAW) Submerged Arc Welding (SAW)

This path is necessary for any WPS that falls outside the prequalified envelope. This includes unusual joint geometries, exotic base metals, high heat inputs, the GMAW-S process, or any other combination not explicitly listed as prequalified. In this case, a Procedure Qualification Record (PQR) must be created. This involves welding and destructively testing test coupons (tension, bend, macroetch, and Charpy V-notch impact if required) to prove the procedure is sound. This path is more time-consuming (weeks vs. hours) and costly, but it provides maximum flexibility.

The standard requires that welded joints be inspected and tested to ensure that they meet the requirements of the standard. The types of inspection and testing required include:
