1. What is Thickness of Plate given Axial Load on Weld?

The thickness of plate given axial load on weld calculation determines the required plate thickness to withstand a specific axial load applied through welded connections, considering the shear stress capacity and weld lengths.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Thickness of Plate = \frac{Axial Load on Weld}{Shear Stress \times (Length of Top Weld + Length of Bottom Weld) \times 0.707} \]

Where:

Axial Load on Weld — Force applied along the axis of the weld (N)
Shear Stress — Maximum allowable shear stress in the material (Pa)
Length of Top Weld — Length of the top weld segment (m)
Length of Bottom Weld — Length of the bottom weld segment (m)
0.707 — Conversion factor for weld throat thickness

Explanation: The formula calculates the minimum plate thickness required to safely transfer the axial load through the welded connections without exceeding the material's shear stress capacity.

3. Importance of Plate Thickness Calculation

Details: Accurate plate thickness calculation is crucial for structural integrity, ensuring welded connections can safely transfer loads without failure or excessive deformation.

4. Using the Calculator

Tips: Enter axial load in Newtons, shear stress in Pascals, and weld lengths in meters. All values must be positive and greater than zero for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Why is the 0.707 factor used in the formula?
A: The 0.707 factor converts the weld leg length to throat thickness, which is the effective load-bearing area in fillet welds.

Q2: What units should be used for input values?
A: Use Newtons for axial load, Pascals for shear stress, and meters for weld lengths to maintain consistency in SI units.

Q3: How does weld length affect plate thickness?
A: Longer weld lengths distribute the load over a larger area, reducing the required plate thickness for a given axial load.

Q4: What safety factors should be considered?
A: Appropriate safety factors should be applied to the calculated shear stress based on material properties, loading conditions, and applicable design codes.

Q5: Can this formula be used for different weld configurations?
A: This formula is specifically for parallel fillet welds. Other weld configurations may require different calculation methods.
