1. What is the Peak Temperature Equation?

The Peak Temperature Reached at Some Distance equation calculates the maximum temperature reached at a specific distance from the fusion boundary during welding or thermal processes. This is crucial for understanding heat distribution and material behavior during thermal operations.

2. How Does the Calculator Work?

The calculator uses the Peak Temperature equation:

\[ T_p = T_a + \frac{H_{net} \times (T_m - T_a)}{(T_m - T_a) \times \sqrt{2\pi e} \times \rho_m \times t \times Q_c \times y + H_{net}} \]

Where:

\( T_p \) — Peak Temperature Reached at Some Distance (K)
\( T_a \) — Ambient Temperature (K)
\( H_{net} \) — Net Heat Supplied Per Unit Length (J/m)
\( T_m \) — Melting Temperature of Base Metal (K)
\( \rho_m \) — Density of Metal (kg/m³)
\( t \) — Thickness of Filler Metal (m)
\( Q_c \) — Specific Heat Capacity (J/kg·K)
\( y \) — Distance from the Fusion Boundary (m)
\( \pi \) — Archimedes' constant (3.141592653589793)
\( e \) — Napier's constant (2.718281828459045)

Explanation: The equation models how temperature decreases with distance from the heat source, accounting for material properties and heat input characteristics.
