What is the effect of excessive heat in SMAW welding?
✔✔ It can cause burn-through, excessive spatter, and weak welds
How can a welder avoid undercut in a weld?
✔✔ By maintaining the correct travel speed and heat input
Why is maintaining a proper arc length critical in SMAW?
✔✔ It ensures stable arc behavior and consistent weld quality
What could happen if the electrode holder is not properly grounded?
✔✔ It may lead to electrical hazards and poor weld quality
What is the result of using the wrong electrode type for a weld?
✔✔ It can cause poor fusion, weak joints, and weld failure
1
,How does a welder prevent electrode sticking during SMAW?
✔✔ By maintaining a consistent arc length and avoiding excessive force on the electrode
What does the "slag" do during the cooling phase of welding?
✔✔ It cools and solidifies over the weld, preventing contamination until it’s removed
What is the consequence of too much travel speed in SMAW?
✔✔ It leads to insufficient penetration and a weak bond
What is the ideal angle for the electrode when welding in SMAW?
✔✔ Around 15 to 30 degrees to the workpiece for good arc stability
Why should the workpiece be clean before welding?
✔✔ To prevent contaminants from causing porosity and weak welds
What would happen if an electrode is stored improperly?
✔✔ Moisture absorbed by the electrode can lead to hydrogen-induced cracking in the weld
2
, How does too short of an arc affect the weld?
✔✔ It can cause poor penetration, excessive spatter, and weak welds
What does "slag inclusion" mean in welding?
✔✔ When slag is trapped in the weld pool, compromising the weld’s strength
Why do welders need to adjust their amperage settings?
✔✔ To match the electrode size and thickness of the material being welded for optimal results
How does a welder prevent arc blow?
✔✔ By adjusting the welding technique and the position of the workpiece to minimize magnetic
interference
Why is controlling the speed of welding important?
✔✔ It ensures proper heat distribution and avoids problems like overheating or inadequate
fusion
