The nozzle axis is 90 to the flat head, as well as the add-on weld includes a 3/8-inch fillet weld. The examiner can easily gauge the fillet weld to ensure compliance.

The Single Strategy To Use For Mig Welder

This instance becomes even more essential if the nozzle is installed at an angle apart from 90 (Fig. 3).
