As the title suggests, I couldn’t find out what TRCAK WELDING means. Literally, it seems to mean track welding, but that doesn’t seem quite right. I seek guidance from someone wise.
The context and industry – could you give a brief overview?
If we think about it the other way around, welding track is easier to understand; tack welding refers to spot welding, that is, temporary welding, while for track welding, one needs to consider the context to figure it out
track weld temporary spot welding, intermittent welding, pre-welding

Track welding in place of spot welding is permitted: intermittent continuous welding, for example, welding 50 mm, leaving 100 mm, and then welding another 50 mm. . . . .
