Big misalignment

Big misalignment

Big misalignment


Dear All,

During a randam inspection for the welding activites I found a big misalignment for a butt joint , more than 3.5 mm(according to AWS D1.1 the shall
not exceed 10% of the thickness of the thinner part joined, or 1/8 in) so please i would like to know the problemes that we can have if they don't repear this matter like the stress concentration...

Best regard

RE: Big misalignment

As an option, research tapered joints as that may work.

RE: Big misalignment

It will have a considerable affect on the joint if it is under fatigue loading.

If it is a long joint your vessel shell thickness is effectively 3.5mm thinner. Potentially even thinner if the effects of the stress concentrations and bending stresses are considered.
