Guideline 1: Joint Finishes

These voluntary guidelines were developed by the NOMMA Standards Committee, with strong input from the membership.

All samples shown are primed steel.

Example D: 1 1/2" to 1 1/2" pipe "T" raked


Finish #1 - No evidence of a welded joint.	Finish #2 -Completely sanded joint, some undercutting and pinholes OK.

Finish #3 -Partially dressed weld with spatter removed.	Finish #4 -Good quality, uniform undressed weld with minimal spatter.

These guidelines are voluntary recommendations for informational purposes only. It is the responsibility of the individual to ensure proper construction design, method, and materials and code compliance.

The use of fillers is not included in the scope of this work. The guidelines do not endorse or discourage use of fillers. They deal with finished appearance only.
