Al,
Take a look at D1.1 latest revision clause 5.17.1
“(1) Tack welds and construction aid welds shall be
made with a qualified or prequalified WPS’s and by
qualified welding personnel”
No matter how you define “tack” weld or construction aid welds....Whether it’s consumed, removed or left on the weldment, all procedure and performance requirements are in force.
