Cracks, structural gouges, or failed welds must be entirely removed using carbon arc gouging, grinding, or machining. The area must then be inspected via MT or PT to verify the defect is gone before re-welding. Postweld Heat Treatment (PWHT)

This section establishes the allowable stresses for different types of joints (groove, fillet, plug, and slot welds). Because cranes are subjected to fatigue from constant lifting cycles, this chapter provides specific formulas and stress-range curves to prevent fatigue cracking over the equipment's lifespan. 2. Workmanship and Technique

AWS D14.1 contains strict rules regarding cyclically loaded joints to minimize structural fatigue. The full document charts the explicit limitations of Complete Joint Penetration (CJP) versus Partial Joint Penetration (PJP) welds. For instance, intermittent groove welds are completely prohibited except in secondary non-load-bearing members. 2. Prequalified Welding Procedure Specifications (WPS)

It is far more than a set of guidelines; it is a legally enforceable standard. The code is directly referenced by the and AISC 360 , the main specifications for structural steel buildings. This means that failing to adhere to AWS D1.1 isn't just a quality issue—it's a building-code violation with serious legal and safety implications.

AWS D14.1/D14.1M provides specifications for welding industrial and mill cranes and material handling equipment, requiring documentation such as Procedure Qualification Records (PQR) and Welder Performance Qualification Records (WPQR). The standard applies to steel weldments, including specific requirements for inspection and testing. The full standard can be purchased through the AWS Bookstore . AWS D14.1/D14.1M - Accuris Standards Store

: Provides precise, code-specific definitions for hundreds of welding terms to ensure clear communication and prevent misinterpretation among all project parties.

This specification does not apply to construction-site tower cranes or crawler-type mobile cranes. Additionally, the welding of crane runways or tracking rails falls outside this scope and must comply with the AWS D15.2 Rail Welding Specification. 2. Structural Design and Stress Analysis

AWS D14.1 is the essential guideline for ensuring the structural integrity of industrial cranes. Adhering to its requirements for joint design, procedure qualification, and inspection is paramount for safety and longevity of equipment.

Before welding, the procedure must be proven. The code dictates how to test the WPS (WPS qualification) to ensure the weld possesses the required strength. It also sets guidelines for welder performance qualification (welding tests) to ensure the welder can produce a sound weld 0.5.2. 4. Workmanship and Technique
