Which of the following is NOT a listed hardfacing pattern?

• A. Stripes
• B. Zig zag
• C. Dots
• D. Waffle

Answer: (A)

Hardfacing patterns determine how the wear surface is built up and covered, aiming for even coverage and reliable wear resistance. Patterns like zig zag, dots, and waffle are designed to spread weld material across the surface in a way that fills the area and avoids long uncoated lanes or excessive heat buildup. Stripes, on the other hand, would leave linear bands with gaps between passes, leading to uneven coverage and weaker wear resistance. Because of this, stripes isn’t listed as a standard hardfacing pattern, while the other options are commonly used.
