I would appreciate any help in determining what the thickness definition of AWS D1.1 is regarding preheating. If I may further explain: A customer is stating that they want 1 1/2" thicknesses preheated to 150 F which was not included in previous pricing for fabrication. The push-back from our adder to go beyond what D1.1 states is: The customer wants all of the plates measured with a mic and if anything (which will be all) are over 1.500, 150 preheat is expected. I have seen "nominal" thickness used all over D1.1 but not applied to preheat thicknesses. So, 1.51" measured plate would need 150 degree F preheating?
