What is the weld thickness? Which weld process are you using?

Thank you for your cooperation.
GMAW IS OUR WELDING PROCESS.Thickness of base plate 80mm and stiffener that conneted to them is also 80 mm. we use CJP (complete joint preparation) connection for stiffener to column base plate.AWSd1.1 is dwg standard for manufacturing.

CJP is complete joint penetration (the weld is welded solid all the way through) not complete joint preparation - the weld joint is prepped all the way through.
