AWS D1.1 classifies structures into which two general categories for inspection purposes?
Answer: Statically loaded and cyclically loaded
AWS D1.1 uses statically loaded and cyclically loaded categories, which have different inspection acceptance criteria.
Which AWS code would be used for welding titanium structures?
Answer: AWS D1.9
AWS D1.9 is the Structural Welding Code for Titanium.
Heat input in welding codes is important because it directly affects:
Answer: Weld metal microstructure and mechanical properties
Heat input influences the heat-affected zone size and cooling rate, directly affecting the mechanical properties of the weld.
Under AWS codes, a Welding Procedure Specification must be signed by:
Answer: A responsible welding engineer or authorized representative
A WPS must be prepared and signed by a responsible welding engineer or authorized representative familiar with the applicable code.
AWS D1.1 requires that tack welds incorporated into the final weld be made by:
Answer: Qualified welders using the applicable WPS
Tack welds that become part of the final weld must be made by qualified welders following the applicable WPS.
AWS D1.1 minimum preheat requirements are primarily intended to prevent:
Answer: Hydrogen-induced (cold) cracking
Preheat slows the cooling rate and allows hydrogen to diffuse out of the weld, preventing hydrogen-induced (cold) cracking.
