Question

the essential elements for making a good weld when using the smaw process are?

correct electrode size, angles and amperage
proper arc length
proper travel speed
all these are correct

Explanation:

Identify the core requirements of SMAW

Using the Welding Success Factors and SMAW knowledge points, we analyze the variables that a welder must control to produce a high-quality weld in Shielded Metal Arc Welding (SMAW). These variables are often referred to as the "five essentials" of SMAW.

Evaluate the individual options

• Correct electrode size, angles and amperage: The correct electrode diameter must match the plate thickness, the electrode angle (travel and work angles) controls puddle shape/penetration, and the amperage must be set within the recommended range for the electrode to prevent lack of fusion or undercut.
• Proper arc length: The distance from the tip of the electrode core wire to the weld puddle must be kept consistent (typically equal to the diameter of the core wire) to maintain arc stability and proper shielding gas coverage.
• Proper travel speed: Moving too fast causes a thin, weak bead with poor penetration; moving too slow causes excessive buildup, slag inclusion, or burn-through.

Determine the correct choice

Since all three individual options represent critical, essential elements required to make a successful weld using the SMAW process, they are all correct. Therefore, the final option "All these are correct" is the correct choice.

Answer:

• Correct electrode size, angles and amperage
• Proper arc length
• Proper travel speed
• All these are correct (Correct answer)
