Welding simulation Assignment $-$ II

Casting and Welding $($S$1-24\_$ETZC$235/$PEZC$236)$

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$)$

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

where,

$f_1-$ heat trans fer coefficient $=0\mathrm{.}7$

$f_2-$ 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

Perform the weld $2\mathrm{.}5$ D to determine the optimal set of process parameters for welding

Compare the isotherm plots of calculated process parameters and parameters obtained from

weld $2\mathrm{.}5$ D using iso $2\mathrm{.}50.$

Write a brief description of the above comparison $($handwritten$)$

Include all your handwritten documents and screenshots into one pdf$,$ then submit to the

canvas.
