Question

1. what is the primary reason for using root passing in smaw welding?

a) to create a decorative pattern on the weld bead
b) to provide additional support to the workpiece
c) to achieve full penetration and fusion in the joint
d) to reduce the overall welding time

1. in smaw welding, what isslinger?

a) a type of welding defect
b) a tool used to strike the arc
c) a slang term for the welding machine
d) a type of filler material

1. what is the purpose of post - weld inspection in smaw welding?

a) to ensure the workpiece is cooled to room temperature
b) to evaluate the quality of the weld and detect defects
c) to apply additional filler material to the weld
d) to clean the workpiece

1. which of the following is a common industry standard for smaw electrode classification?

a) aws (american welding society)
b) gps (global positioning system)
c) cdc (center for disease control)
d) atm (automated teller machine)

Explanation:

• Question 47: In SMAW (Shielded Metal Arc Welding), "root gouging" is mainly done to achieve full penetration and fusion in the joint. Decorative patterns (a) are not the main goal. Additional support (b) is not its primary function. Reducing welding time (d) is not the key reason.
• Question 48: A "slinger" in SMAW welding is a type of welding defect. It is not a tool (b), a slang term for the machine (c), or filler material (d).
• Question 49: The purpose of post - weld inspection is to evaluate the quality of the weld and detect defects. Cooling to room temperature (a) is not its main purpose. Applying more filler (c) and cleaning (d) are not the main reasons for inspection.
• Question 50: AWS (American Welding Society) is a common industry standard for SMAW electrode classification. GPS (b) is for positioning, CDC (c) is for disease control, and ATM (d) is for banking transactions.

Answer:

1. c) To achieve full penetration and fusion in the joint
2. a) A type of welding defect
3. b) To evaluate the quality of the weld and detect defects
4. a) AWS (American Welding Society)
