Problem Solved: Out-of-Tolerance Fillet Weld Joints
Have you encountered fit-up problems in the field for fillet welded connections? What has been your solution? AWS D1.1 requires that the engineer approve any alternative acceptance criteria for production welds, but the Code only provides general stipulations applicable to most situations. Finding an acceptable alternative for fit-up issues often plagues engineers, however in the Second Edition of Design Guide 21: Welded Connections, Chapter 15.4.2 offers solutions for out-of-tolerance weld joints.
In the August 2019 SE University session, Duane Miller, PE, from The Lincoln Electric Company, presented Introducing Design Guide 21: Welded Connections (Second Edition). Duane covered some unique requirements for special welding applications, suggested potential solutions to frequently encountered problems associated with welded construction, and reviewed the approach used in AWS D1.1 to address unusual situations and the role of the EOR.
Duane addressed how out of tolerance fillet weld joints might be handled according to Design Guide 21. Watch this short 4 minute video to hear Duane discuss buttering and changing the fillet weld to a CJP groove weld as two solutions for out-of-tolerance fillet weld joints.
