Hi!
According to table 341.3.2, note 5, surface porosity is only evaluated for welds equal or less than 5mm nominal thickness. Where, then are limits for welds greater than 5mm (3/16)? or are there none?
Must be a limit on surface breaking pores/porosity for weld greater than 5mm (3/16) in thickness?
edit:This is not high pressure pipe work.
