SENSE Module 4 SMAW Questions and
Answers | Latest Version | 2024/2025 |
Correct & Verified
What does SMAW stand for in welding?
✔✔ Shielded Metal Arc Welding.
What is the primary purpose of the electrode in SMAW?
✔✔ To provide filler material for the weld and conduct electrical current.
What type of current is commonly used in SMAW?
✔✔ Both direct current (DC) and alternating current (AC).
What is the function of the flux in the electrode coating during SMAW?
✔✔ To protect the molten weld pool from contamination and to stabilize the arc.
Why is it important to maintain the correct arc length in SMAW?
✔✔ To ensure good weld quality and prevent defects like porosity or lack of fusion.
1
,What is the typical range of amperage used for SMAW?
✔✔ Generally between 40 and 250 amps, depending on the electrode size and material thickness.
How does the electrode size affect the SMAW process?
✔✔ A larger electrode size requires higher amperage, while a smaller electrode size is used for
thinner materials.
What is the purpose of weaving the electrode in SMAW?
✔✔ To ensure even heat distribution and proper fusion along the joint.
What is a common defect associated with improper welding technique in SMAW?
✔✔ Undercut, where the base metal adjacent to the weld is melted and left unfilled.
How does the position of the welder affect the SMAW process?
✔✔ The position, such as flat, horizontal, vertical, or overhead, impacts arc control and weld
quality.
What is the function of slag in SMAW?
2
, ✔✔ To protect the cooling weld bead from air contamination and help solidify the weld metal.
Why is it important to remove slag between passes in SMAW?
✔✔ To ensure good adhesion between weld layers and avoid inclusions.
What is the typical angle for the electrode when welding in the flat position using SMAW?
✔✔ The electrode is generally held at a 90-degree angle to the workpiece.
How does the travel speed affect the quality of a weld in SMAW?
✔✔ Too fast a travel speed can lead to incomplete fusion, while too slow can cause excess heat
and spatter.
What causes spatter in SMAW?
✔✔ Incorrect voltage, excessive current, or improper electrode angle can cause excessive spatter.
What is the importance of joint preparation before starting an SMAW weld?
✔✔ Proper joint preparation ensures good fit-up, reduces the risk of defects, and makes welding
easier.
