1. What is Tensile Force on Plates in Transverse Fillet Weld?

Definition: This calculator determines the tensile force that plates joined by transverse fillet welds can withstand based on weld dimensions and material stress.

Purpose: It helps engineers and welders ensure weld joints can handle expected loads without failure.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_t \) — Tensile force on plates (Newtons)
• \( \sigma_t \) — Tensile stress in weld material (Pascals)
• \( h_l \) — Leg length of the weld (meters)
• \( L \) — Length of the weld (meters)

Explanation: The formula accounts for the effective throat area of the fillet weld (0.707 × leg length) multiplied by the weld length and material stress.

3. Importance of Calculation

Details: Proper calculation ensures weld joints can withstand service loads without exceeding material strength limits, preventing catastrophic failures.

4. Using the Calculator

Tips: Enter the tensile stress, weld leg length, weld length, and optional tolerance percentage. All dimensional values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is there a 0.707 factor in the formula?
A: The 0.707 factor accounts for the effective throat thickness of a 45° fillet weld (leg length × cos45°).

Q2: What's a typical tensile stress for weld materials?
A: Common structural steels have tensile strengths of 400-700 MPa, but always check your specific material specifications.

Q3: How does tolerance affect the calculation?
A: The tolerance (±5% by default) provides a safety range accounting for material variations and workmanship.

Q4: What if my weld isn't at 45°?
A: The formula assumes standard 45° fillet welds. For other angles, use the appropriate trigonometric factor.

Q5: Does this include safety factors?
A: No, the result is theoretical capacity. Apply appropriate safety factors per your design code requirements.
