Under AWS D1.1, what is the minimum bend diameter (as a multiple of specimen thickness 't') for a guided bend test of a 1-inch thick specimen for steel with 72 ksi minimum tensile strength?
Answer: 4t
AWS D1.1 specifies a minimum bend diameter of 4t for steels with minimum specified tensile strength of 72 ksi or less.
Which AWS standard covers filler metal classification for bare solid wire electrodes used in GMAW of carbon steel?
Answer: AWS A5.18
AWS A5.18 covers carbon steel electrodes and rods for GTAW and gas-shielded GMAW welding.
A welder who fails the visual examination portion of a qualification test may:
Answer: Not retest until additional training has been completed
Under AWS D1.1, a welder who fails a qualification test shall not retest until additional practice or training has been performed.
What is the significance of the 'F-number' in AWS A5.1 and related filler metal standards?
Answer: It groups filler metals with similar usability characteristics for WPS and welder qualification purposes
F-numbers group electrodes by similar usability characteristics; a welder qualified with one F-number electrode is qualified for other electrodes in the same group.
Under AWS D1.1, what is the maximum allowable convexity for a single-pass fillet weld with a 5/16 in. leg size?
Answer: 3/32 in.
AWS D1.1 limits fillet weld convexity to 3/32 in. for welds with a leg size over 5/16 in.; for 5/16 in. legs it is 3/32 in.
The 'A-number' classification system in AWS filler metal standards is used to:
Answer: Identify the chemical composition of the weld deposit for WPS qualification purposes
A-numbers classify weld metal chemical compositions and are used to group filler metals for procedure qualification under ASME and AWS standards.
