A padeye crack is found during cargo operations. The surface is oily, and vibration from the winch continues. Which action ensures a safe temporary weld?
Weld as found with slightly higher heat
Secure machinery, clean surface, add support
Patch directly without removing vibration
Cool the weld with water during operation
A minor hull crack near a frame is stable but may grow in heavy seas. What weld-based action prevents progression?
Slow vessel to reduce overall stress
Drill ends and weld a fitted doubler plate
Fill the crack using wide, hot passes
Place a gasket sheet over the cracked area
A seawater cooling line develops a pinhole leak under flow and cannot be fully isolated. What is the safest temporary weld action?
Weld over the leak in its flowing state
Heat the pipe to counteract pressure
Clamp the area and seal after reducing flow
Stop all cooling and weld with full heat
A machinery foundation bracket fractures, causing vibration. What temporary weld method prevents worsening of the damage?
Restore strength through deep passes
Add short controlled fillets to limit shift
Soften the bracket using gas heating
Tighten bolts and leave crack untouched
A bent ladder section must be cut free to release a trapped hydraulic line. What concern must be addressed before gas-cutting?
Torch flow adjustment
Oxygen supply setting
Residues behind the ladder
Open flames nearby
A cracked stiffener inside a store room requires welding. Which step is essential before work begins?
Use larger electrodes for quicker work
Switch to gas welding to reduce sparks
Test air and install forced ventilation
Weld with door partly open for airflow
A leaking steam-drain flange must be temporarily repaired with low distortion. Which technique fits best?
Fast high-heat arc passes
Low-temp gas brazing work
Deep-arc penetration welds
High-force arc adjustments
A thin corroded plate needs a temporary welded cover. Which approach avoids burn-through?
Hot wide passes for bonding
Inside welding only approach
Short stitch beads for control
Large rods for fast buildup
A padeye crack requires repair while cargo crane loads swing in moderate wind. What is the correct decision?
Weld while slowing crane travel
Continue work with reduced sway
Stop lifting and isolate the area
Weld only when load swings clear
A temporary patch is placed on a seawater line. What action ensures proper follow-up?
Keep patch until next port call
Monitor leaks and plan class repair
The safest way to shut down gas welding equipment is to close:
Torch oxygen first
Torch fuel first
Cylinder fuel first
Cylinder oxygen first
A regulator creep condition is suspected when:
Pressure holds low
Pressure rises idle
Gauge line rattles
Needle drops slow
During confined-space welding, continuous monitoring must verify:
Still air lines
Safe oxygen band
Cool bulkhead skin
Low floor drafts
A junior welder reports intermittent popping at the torch while cutting brackets near a paint-store bulkhead. The most likely cause is:
Tip partial block
Low plate heat
High gas swirl
Mild rod bends
You are cutting an old bulkhead section. Slag begins collecting in a narrow recess overhead, threatening to fall. The proper action is to:
Stop and clear
Tilt torch more
Increase speed
Extend hose run
