Tube Chassis Welders?

[obi-1]

@Fiero

We saw locational bending stresses on #3 because the tubes were welded together slightly bent (1-3 degrees, you can notice it in the photos). So when the tube was pulled axially it was also bending as it tried to straighten out.

Ah. I see.

@Jeff95TA

Those are all pretty close numbers, that’s encouraging. Did you do any hand calcs to see what theoretical failure is?

If you had time you could even model some welds in ANSYS to see what it gives you. And when the database becomes corrupt you can do a CDWRITE/CDREAD to fix it (that was intended for obi-1 :))

:bowrofl: Sound like a reasonable workaround to me! :bowrofl:
