The formula for calculating thermal conductivity is heat multiplied by the distance divided by the product of surface area times the temperature gradient. NDT Resource Center explains that thermal conductivity is the property of a material to conduct heat.The thermal conductivity of a material is a measure of its ability to conduct heat.It is commonly denoted by , , or .. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity. The defining equation for thermal conductivity is : Heat Flux = -k * (Temperature 2 – Temperature 1)/Thickness. Every substance has the capacity to conduct heat on its own. The thermal conductivity of a material is described by the formula: K = (QL)/(AΔT) Where, K is the thermal conductivity in W/m.K.

Thermal Conductivity. The heat generated in high thermal conductivity materials is conducted away from the region of the weld . For metallic materials, the electrical and thermal conductivity correlate positively, i.e. materials with high electrical conductivity (low electrical resistance) exhibit high thermal conductivity.
