neutral  Marc Brunet: mmm, .. the passage talks more about a pre-welding surface clean-up operation, and so grinding at an angle near parallel to the surface(s) to be welded, rather than cutting a bevel trough for the weld bead, don't you think?

  -> Thank you! This may not be specific to welding. It could be any kind of groove cutting. I think a more generic term is a safer bet.

Reference information:
IMO, this is what this passage is talking about. See link...

What we learn from it, among alternatives :

Angle grinding is not really the best option to do that scrubbing job, if the following considerations must come first:

- eliminating all inclusions and pollutants when preparing a material’s surface for welding
- Removing too much of the base material during pre-weld surface preparation can also affect weld penetration, impacting the strength and integrity of the finished weld.

Looking back on the quoted sentence, David is correct: 3 operations are listed here: and the last two cleaning ones I focused on do not qualify the first which consists in preparing a groove for the welding phase, usually by bevelling the edges of the two surfaces to be welded together. My apologies, David.
