1. A certified structural welder working on a multistory commercial steel-
frame building in California is assigned to perform complete joint
penetration groove welds on ASTM A992 wide-flange beams
connecting to seismic moment frames. According to structural welding
requirements commonly enforced under California building codes and
AWS D1.1 Structural Welding Code – Steel, which procedure is MOST
critical before welding begins to ensure compliance with qualification
standards and seismic performance expectations?
A. Allowing welders to select any electrode classification provided the
tensile strength exceeds 60 ksi
,B. Verifying that the welder is familiar with blueprint reading but not
requiring procedure qualification records
C. Reviewing approved Welding Procedure Specifications (WPS), Procedure
Qualification Records (PQR), and verifying welder performance qualifications
for the specific process and position
D. Conducting visual inspection only after welding is completed without
reviewing prequalified procedures
C. Reviewing approved Welding Procedure Specifications (WPS), Procedure
Qualification Records (PQR), and verifying welder performance
qualifications for the specific process and position
Structural seismic welding in California requires strict adherence to AWS
D1.1 qualification standards. Approved WPS documents, supporting PQRs
where required, and properly qualified welders ensure that welds meet
strength, ductility, and seismic performance requirements before
fabrication begins.
2. During inspection of a structural steel fabrication shop, a welding
inspector discovers that shielded metal arc welding electrodes
classified as E7018 have been stored in an open container exposed to
humid air for several days. What is the PRIMARY concern associated
with using these electrodes without proper reconditioning?
,A. Increased deposition rate causing excessive reinforcement
B. Hydrogen-induced cracking due to moisture absorption in low-hydrogen
electrodes
C. Excessive arc blow resulting from magnetic interference
D. Reduced electrical conductivity causing lower amperage readings
B. Hydrogen-induced cracking due to moisture absorption in low-hydrogen
electrodes
E7018 electrodes are low-hydrogen electrodes designed to minimize
hydrogen cracking in structural steel welds. Exposure to moisture allows
hydrogen absorption into the flux coating, increasing the risk of delayed
cracking, particularly in restrained joints and thick structural members.
3. A welder performing overhead groove welds on structural columns
notices excessive weld spatter, undercutting at the toes, and
inconsistent bead contour. Which adjustment would MOST likely
improve weld quality while maintaining structural code compliance?
A. Increasing travel speed significantly while raising voltage
B. Reducing amperage to an excessively low setting to prevent penetration
C. Adjusting amperage and travel speed to achieve proper puddle control
and electrode manipulation
D. Eliminating slag removal between weld passes
, C. Adjusting amperage and travel speed to achieve proper puddle control
and electrode manipulation
Proper amperage and travel speed are essential for maintaining puddle
control in overhead welding. Excessive amperage or improper travel can
produce undercut and spatter, while proper adjustment ensures sound
fusion, acceptable bead shape, and code-compliant weld quality.
4. In structural welding inspection terminology, what is the BEST
definition of incomplete fusion?
A. A condition in which the weld metal completely penetrates the joint root
B. Failure of weld metal to fuse completely with the base metal or preceding
weld bead
C. A crack occurring in the heat-affected zone after cooling
D. Excessive penetration extending beyond the root opening
B. Failure of weld metal to fuse completely with the base metal or
preceding weld bead
Incomplete fusion is a serious discontinuity where weld metal does not
properly bond with the base material or previous weld pass. This defect
reduces effective weld strength and is unacceptable in critical structural
applications governed by AWS D1.1.
