1. What is Resistance of Bottom Weld given Axial Load on Angle?

Definition: This calculator determines the resistance capacity of the bottom weld when an axial load is applied to an angle, considering the resistance of the top weld.

Purpose: It helps structural engineers and welders ensure proper weld design and load distribution in angle connections.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F2 \) — Resistance of bottom weld (Newtons)
• \( P_{angle} \) — Axial load on angle (Newtons)
• \( F1 \) — Resistance of top weld (Newtons)

Explanation: The resistance of the bottom weld is calculated by subtracting the top weld's resistance from the total axial load on the angle.

3. Importance of Weld Resistance Calculation

Details: Proper weld resistance estimation ensures structural integrity, load distribution, and safety in welded connections.

4. Using the Calculator

Tips: Enter the axial load on angle and resistance of top weld (both in Newtons). The values should be positive and the axial load should be greater than or equal to the top weld resistance.

5. Frequently Asked Questions (FAQ)

Q1: Why is there a ±5% tolerance?
A: The tolerance accounts for variations in material properties, welding conditions, and measurement uncertainties.

Q2: What if my axial load is less than top weld resistance?
A: The calculator won't compute as this indicates an invalid condition where the top weld alone can support more than the applied load.

Q3: How do I determine the axial load on an angle?
A: The axial load is typically determined through structural analysis of the entire system.

Q4: What units should I use?
A: The calculator uses Newtons (N) for all values. Convert other units to Newtons before input.

Q5: Does this include safety factors?
A: No, you should apply appropriate safety factors to the calculated resistance based on your design standards.
