Weld Penetration Ratio Tool
Analyze the shape of your weld by calculating the penetration-to-width ratio. This is a key metallurgical indicator of weld quality and solidification behavior.
Enter Weld Dimensions
Measure and enter the bead width and penetration depth from a weld cross-section.
The Shape of Fusion
The cross-sectional shape of a weld bead is as important as its size. The penetration-to-width ratio (P/W ratio) is a simple way to quantify this shape. It's a critical factor in determining how the weld solidifies, which in turn affects its susceptibility to defects like solidification cracking. Engineers and researchers use this ratio to develop and qualify welding procedures.
