What is the toe of the weld?

The toe of the weld refers to the point where the weld metal meets the base material, specifically at the outer edge of the weld joint. It is a critical area that can be susceptible to defects such as cracks or incomplete fusion. Proper preparation and technique are essential to ensure a strong bond at the toe, as it significantly influences the overall integrity of the weld. The quality of the toe can impact the performance and durability of the welded structure.
