Predicting the variation in the final assembly given the variation
in the parts and tooling is of interest to automobile and aerospace
industries alike. I will present a simple model of welding and
clamping of beams that demonstrates that the order in which
the clamps and welds are imposed influences the final shape
of the assembly. Additionally, using statistical methods we
show that clamping and welding from the inside out leads to
a smaller standard deviation in the result (as measured by the
displacement of the right end of the beams) in response to normal
distributions of variations parts and welding.
