1. What is Resistance of Weld Per Unit Length?

Resistance of weld per unit length is a function of the resistivity and surface condition of the parent material. It represents the resistance offered by the weld per unit length of the welding segment.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ s = \frac{F1 \times (a + b)}{L \times b} \]

Where:

\( s \) — Resistance of weld per unit length (Newton)
\( F1 \) — Resistance of top weld (Newton)
\( a \) — Distance of top weld from gravity axis (Meter)
\( b \) — Distance of bottom weld from gravity axis (Meter)
\( L \) — Total length of weld (Meter)

Explanation: This formula calculates the resistance offered by the weld per unit length based on the resistance of the top weld and the geometric configuration of the welding setup.

3. Importance of Weld Resistance Calculation

Details: Accurate calculation of weld resistance per unit length is crucial for structural integrity analysis, weld design optimization, and ensuring proper load distribution in welded joints.

4. Using the Calculator

Tips: Enter all values in appropriate units. Resistance values should be positive, and distances should be non-negative with bottom weld distance greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect weld resistance?
A: Weld resistance is influenced by material resistivity, surface conditions, welding technique, and the geometric configuration of the weld.

Q2: How is this calculation used in practice?
A: This calculation helps engineers determine the appropriate weld size and configuration to withstand expected loads in structural applications.

Q3: What are typical values for weld resistance?
A: Values vary significantly based on materials and welding conditions. Consult material specifications and welding codes for appropriate values.

Q4: Are there limitations to this formula?
A: This formula provides an approximation and may need adjustment for complex weld geometries or unusual material combinations.

Q5: How does weld length affect resistance?
A: Longer weld lengths generally distribute stress more effectively, but the relationship is not linear and depends on the specific application.
