dL/dT = αL*L, where L is the length of the steel, T is temperature, and αL is the linear thermal expansion coefficient which for steel is about 11.0 to 13.0. That is possibly the easiest differential equation in history: (1/L)dL = (αL)dT ln(L) = αLT L = eαLT

Harder than work piece High thermal conductivity High heat transfer coefficient
The alloy used for welding should be similar in strength to the bulk material being welded. Otherwise there will be stress concentration at the junction between the two alloys. This problem is somewhat reduced when the metals mix during welding, if the weld point moves slowly enough.
Linear Temperature Expansion Coefficient (10-6 in/in oF) Brass = 10.4 Steel = 7.3 Therefore brass will expand or contract more steel.

The larger the value of μ (aka Mu, the coefficient of friction, the greater the frictional force on an object. For instance, steel on nonlubricated steel has a μ of 0.58 while steel on lubricated steel has a μ of 0.06.

The linear contraction of 1500 cm of steel pipe cooled through 70°C can be calculated using the formula ΔL = L0 * α * (T2-T1), where L0 is the original length of the pipe, α is the coefficient of linear expansion for steel, and T2 and T1 are the final and initial temperatures respectively. In this case, the initial temperature is 20°C and the final temperature is 70°C. Thus, the linear contraction of the pipe is calculated as ΔL = 1500 * 12 * 10^-6 * (70 - 20) = 0.024 m.
As current passes through steel, it heats up from resistive heating. As it heats up, it expands. A typical coefficient of thermal expansion for steel is 13x10-6 m/m K but the exact coefficient of thermal expansion of steel depends on the type of steel. For example:Coefficient of Linear Thermal Expansion for:(10-6 m/m K)(10-6 in/in oF)Steel13.07.3Steel Stainless Austenitic (304)17.39.6Steel Stainless Austenitic (310)14.48.0Steel Stainless Austenitic (316)16.08.9Steel Stainless Ferritic (410)9.95.5

thermal expansion depends on Temperature and material of steel
That would depend on the cross sectional area of that linear meter of steel and as you have not told us that we can not answer you. To work out the answer for yourself you need to know the VOLUME of your steel and you multiply this by the density of your steel to give you a weight.
