1. What is Resistance Offered by Weld Per Unit Length?

Definition: This calculator determines the resistance of weld per unit length based on the axial load on the angle and the lengths of the top and bottom welds.

Purpose: It helps engineers and welders calculate the weld resistance needed to withstand specific axial loads in structural connections.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( s \) — Resistance of weld per unit length (N/m)
• \( P_{angle} \) — Axial load on angle (N)
• \( L_{top\ weld} \) — Length of top weld (m)
• \( L_{bottom\ weld} \) — Length of bottom weld (m)

Explanation: The axial load is distributed across the total length of both welds to determine the resistance per unit length.

3. Importance of Weld Resistance Calculation

Details: Proper weld resistance calculation ensures structural integrity, prevents weld failure, and meets safety standards in construction.

4. Using the Calculator

Tips: Enter the axial load in Newtons, lengths of top and bottom welds in meters (default values shown). All values must be > 0. The ±5% indicates typical tolerance in weld length measurements.

5. Frequently Asked Questions (FAQ)

Q1: Why is weld resistance per unit length important?
A: It determines how much load the weld can safely carry without failing, ensuring structural safety.

Q2: What affects weld resistance?
A: Weld material, thickness, length, and quality of welding all affect resistance.

Q3: What's a typical weld length tolerance?
A: ±5% is common for weld length measurements in structural applications.

Q4: How do I determine axial load on an angle?
A: Calculate from structural loads or use engineering analysis of forces.

Q5: Does this calculation account for safety factors?
A: No, you should apply appropriate safety factors based on your design standards.
