In a metal inert gas $($MIG$)$ welding process, the electrical power supplied to the arc is measured at $4\mathrm{.}5$ KVA. The task is to join two aluminium plates, each with a thickness of $8$ mm $,$ using a V$-$joint configuration that has an included angle of $50$ degrees. Assume that the arc is on for $90\%$ of the total time and the heat transfer is two$-$dimensional. Determine the maximum possible welding speed. Use the following material properties:

Steps:

Calculate the weld speed using the formula given below $($attach the handwritten solution$)$

$q$ Travel speed, $v=\frac{f_1{f}_2{Q}_{in}}{U_{m}A}$

where,

$f_1-$ heat transfer coef ficient $=0\mathrm{.}7$

$f_2-$ melting factor $=0\mathrm{.}5$

$U_m-$ Specific heat $=k{T}^2$

$k-3\mathrm{.}33{10}^{-6}$

$T-$ melting point $of$ the material $0$

$Q_{in}-$ heat input
