Real-time application. Fillet weld welded with freehand technique only, diameter of the pipe was around 70 mm. Sometimes you cannot weld with cup walking. I am quite surprised, that people are "obsessed' with cup walking. It's often common to see in WPS's that too big weaving pattern like this one is quite often forbidden and stinger beads are forced to be used, i.e., max width of stringer bead is 3x diameter of filler rod etc.
This particular joint was made using just 2 mm diameter of filler rod. My own "rapid dab of filler rod using freehand technique" was used here and it never failed me. I often try to point out my students, "when you lock yourself to cup walking, there will come troubles with materials like aluminium and so on, not to mention tight spaces...".
Oh, by the way, in my current company here in Norway, they use these standard gas lens bodies on the welding torch. Not even shortened variants. I miss my furick cups, but it is how it is, hard to turn around in circumference, plenty of stops and restarts, but it can be done up to the perfection, where restarts are barerly visible.
