1. What is Tensile Stress in Transverse Fillet Weld?

Definition: Tensile stress in transverse fillet weld is the stress that occurs when the weld is subjected to a tensile force trying to pull apart the welded area.

Purpose: This calculator helps determine the tensile stress in a transverse fillet weld based on the applied load and weld dimensions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \sigma_t \) — Tensile stress in transverse fillet weld (Pa)
• \( P_t \) — Load on transverse fillet weld (N)
• \( h_l \) — Leg of weld (m)
• \( L \) — Length of weld (m)

Explanation: The load is divided by the product of 0.707 (constant for fillet welds), weld leg length, and weld length to determine the stress.

3. Importance of Tensile Stress Calculation

Details: Proper calculation ensures weld integrity under load and helps prevent weld failure in structural applications.

4. Using the Calculator

Tips: Enter the load in newtons, weld leg length in meters (with ±5% tolerance), and weld length in meters (with ±5% tolerance). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the 0.707 factor in the formula?
A: This is a constant that accounts for the geometry of fillet welds, representing the effective throat thickness.

Q2: Why is there a ±5% tolerance on dimensions?
A: Weld dimensions can vary slightly in practice, so this accounts for typical manufacturing tolerances.

Q3: What units should I use?
A: Use newtons for load and meters for dimensions. The result will be in pascals (Pa).

Q4: How do I measure the leg of a weld?
A: The leg is the distance from the joint root to the toe of the weld, measured along the base metal surface.

Q5: What's a typical safe tensile stress for welds?
A: This depends on the material and welding process, but is typically 60-70% of the base metal yield strength.
