1. What is Resistance of Bottom Weld?

Resistance of bottom weld is a function of the resistivity and surface condition of the parent material. It represents the resistance force that the bottom weld can withstand in a welded connection.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ F2 = \frac{s \times L \times a}{a + b} \]

Where:

\( F2 \) — Resistance of bottom weld (N)
\( s \) — Resistance of weld per unit length (N)
\( L \) — Total length of weld (m)
\( a \) — Distance of top weld from gravity axis (m)
\( b \) — Distance of bottom weld from gravity axis (m)

Explanation: This formula calculates the resistance of the bottom weld based on the weld properties and geometric configuration of the welded joint.

3. Importance of Weld Resistance Calculation

Details: Accurate weld resistance calculation is crucial for structural design and safety assessment of welded connections, ensuring that welds can withstand applied loads without failure.

4. Using the Calculator

Tips: Enter all values in appropriate units. Resistance of weld per unit length and total length of weld must be positive values. Distance values must be positive and non-zero.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect weld resistance?
A: Weld resistance depends on material properties, weld quality, surface condition, and geometric configuration of the welded joint.

Q2: How is resistance of weld per unit length determined?
A: It is typically determined through material testing and depends on the resistivity and surface condition of the parent material.

Q3: What is the significance of distance from gravity axis?
A: The distance from gravity axis affects the moment distribution and stress concentration in the welded connection.

Q4: Are there limitations to this calculation method?
A: This method assumes uniform material properties and may not account for complex stress distributions in certain configurations.

Q5: Can this formula be used for all types of welds?
A: This formula is specifically designed for calculating bottom weld resistance in certain geometric configurations and may not apply to all weld types.
