1. During the erection of a multistory structural steel frame for a
commercial building in Texas, a certified structural welder is assigned
to perform complete joint penetration groove welds on ASTM A992
wide flange beams using FCAW in the horizontal position. The welding
procedure specification requires preheat, interpass temperature
control, and strict adherence to AWS D1.1 acceptance criteria. Which
of the following conditions would most likely require immediate
rejection of the weld under structural welding code requirements?
A. Slight convexity exceeding 1/16 inch on the weld face
B. Uniform surface discoloration caused by shielding gas coverage
,C. Visible crack indications extending longitudinally along the weld toe
D. Minor arc strikes outside the weld zone that were ground smooth
afterward
C. Visible crack indications extending longitudinally along the weld toe
Cracks are considered one of the most severe discontinuities in structural
welding because they create stress concentration points that can
propagate under loading conditions and lead to catastrophic structural
failure. AWS D1.1 and Texas structural welding certification standards
generally require immediate rejection and repair of welds containing
cracks regardless of size or location.
2. A structural welding inspector observes a welder preparing to weld a
column splice connection using E7018 low-hydrogen electrodes that
were left exposed to the atmosphere for several hours in humid
conditions. What is the primary reason the inspector may require the
electrodes to be discarded or reconditioned before use?
A. Atmospheric exposure increases electrode deposition rate excessively
B. Moisture absorption can contribute to hydrogen-induced cracking in the
weld
C. Electrode exposure causes excessive reinforcement buildup automatically
D. Humidity exposure permanently changes the base metal tensile strength
,B. Moisture absorption can contribute to hydrogen-induced cracking in the
weld
Low-hydrogen electrodes are designed to minimize hydrogen content in
weld metal. Exposure to moisture allows the flux coating to absorb water,
which decomposes during welding and introduces hydrogen into the weld.
Hydrogen-induced cracking is especially dangerous in restrained structural
steel applications involving thick members or high-strength steels.
3. A welder performing groove welds on structural steel notices
incomplete fusion along the sidewall of the joint after visual
inspection. Which of the following welding variables would most likely
need adjustment to correct this defect?
A. Reducing travel speed and improving electrode manipulation technique
B. Lowering preheat temperature below the specified minimum
C. Increasing the root opening beyond the WPS maximum limit
D. Using a smaller ground clamp closer to the weldment
A. Reducing travel speed and improving electrode manipulation technique
Incomplete fusion occurs when weld metal fails to properly fuse with the
base metal or previous weld passes. Slow travel speed and proper
electrode manipulation allow sufficient heat input and puddle control to
achieve adequate sidewall fusion, which is essential for structural integrity
in certified structural welds.
, 4. In a Texas structural steel fabrication facility, a welder is qualifying
using a 3G vertical groove weld test plate. Why is the vertical position
qualification considered more demanding than the flat position
qualification?
A. Vertical welding eliminates slag formation completely
B. Gravity causes molten weld metal to flow downward, requiring greater
puddle control
C. Vertical welding requires lower amperage than all other positions
D. The weld metal cools slower in vertical welding than in flat welding
B. Gravity causes molten weld metal to flow downward, requiring greater
puddle control
Vertical welding presents a greater challenge because gravity affects the
molten puddle, increasing the risk of sagging, lack of fusion, and uneven
bead profile. Welders must demonstrate advanced control over heat input
and electrode manipulation to produce acceptable welds in the vertical
position.
5. A structural welder is assigned to weld beam-to-column moment
connections in a seismic application. Which welding practice is most
critical for minimizing the likelihood of brittle fracture in these highly
restrained joints?
