dear all,

if the shell dia is bigger and that shell is welded by four plate longitudinal radiography on 3 weld joint will be full and on on weld joint it is spot radiography then which one we have to input for the analysis.

Dear friend

at that time u have to take joint efficiency as applicable for spot radiography.

But if u are doing RT for 3 shell then also do for last shell, otherwise do spot RT for all shell.

sajit patel

your question is not clear How is it possible to have full RT for 3 long seams and spot rt for one long seam of same shell.
However jt efficiency should be taken for spot (lower value)

Why are you spending so much money for 3 welds for full RT?
