WorksheetsSMAW (Stick Welding) Test
Total questions: 13
Worksheet time: 7mins
What does the flux coating on a SMAW electrode do?
Adds filler metal only
Shields the arc and stabilizes the weld
Provides electrical conductivity
Cools the weld bead
SMAW power sources typically are:
Constant voltage (CV) only
Constant current (CC), AC, or DC
Only DC
Pulse current
Why is a short arc length important in SMAW?
Increases slag formation
Reduces spatter and improves bead control
Makes the arc easier to see
Automatically increases penetration
Which of the following is a common hazard with SMAW?
Dust inhalation from grinding only
Electric shock from live circuits
Overheating wire feeder
Laser reflections
The flux on the electrode protects the molten weld pool from:
Excessive heat
The atmosphere
Arc blow
Current flow
SMAW requires an external shielding gas supply.
True
False
Welding with too long an arc length will usually result in:
Stronger welds
Excessive spatter and porosity
Deeper penetration
Improved arc stability
Electrode classification (such as E7018) tells the welder:
Only the brand of electrode
Current type, tensile strength, and positions allowed
Machine voltage settings
The color code of the electrode
If a weld bead has porosity, one likely cause is:
Travel speed too slow
Contaminated base metal or moisture in electrode
Too much penetration
Too short an arc
If penetration is too shallow, you might:
Increase travel speed
Decrease amperage
Increase amperage or reduce arc length
Use smaller diameter electrode
An electrode sticking to the workpiece is usually caused by:
Amperage too low or arc length too short
Arc blow
Current too high
Improper shielding gas
Slag should be removed after each pass because:
It weakens the weld if trapped
It improves arc length
It increases penetration
It helps cooling
Which welding position is most difficult for beginners in SMAW?
Flat
Horizontal
Vertical
Overhead
