Question

Seam welding used for metal sheets having thickness in the range:

• A. 0.025 to 3 mm
• B. 3 to 6 mm
• C. 6 to 10 mm
• D. More than 10 mm

Hint:

For thin metal sheets, seam welding is best suited in the range of 0.025 to 3 mm. For thicker sheets, consider using spot welding or other methods.

Answer 1

The Correct Option is A

Seam welding is commonly used for welding thin metal sheets, and it is most effective for sheet thicknesses in the range of 0.025 to 3 mm. This process is ideal for thin metals as it allows for continuous or near-continuous welding with good control over heat input and minimal distortion.
- 3 to 6 mm is typically the range for spot welding, not seam welding.
- 6 to 10 mm or More than 10 mm are typically too thick for seam welding; other welding methods like MIG or TIG are better suited for these thicknesses.
Thus, the correct range for seam welding is 0.025 to 3 mm.
