what is root radius and toe radius. and how we check root radius and toe radius.

Question

Accepted Answer

Root radius and toe radius are terms used in welding to describe the curvature at the base and top of a weld. They are checked using gauges.

Root radius is the concave curvature at the base of a weld, while toe radius is the convex curvature at the top of a weld.
Root radius is important for ensuring proper penetration and strength of the weld, while toe radius is important for preventing stress concentration and cracking.
Root and toe radius can be checked using gauges specifically designed for this purpose, such as fillet weld gauges or convexity gauges.
The gauges are placed on the weld and the curvature is compared to the gauge to ensure it falls within the acceptable range.
Proper root and toe radius are important for ensuring the quality and safety of welded structures.
