As a welder you are responsible to inspect your own work; you are the first line of inspection. Section 5 of AWS D1.1, Paragraph 5.30.2 requires weld cleaning which is for the purpose of inspection. The welder should look at his finished weld, accept it, and move on to the next weld.
Paras. 6.1.2.1 & 6.1.3.1 specify inspector responsibilities. You, as a CWI, are not performing this responsibility; however, your company's welding inspector is most likely doing so.
AWS D1.1 & AWS D1.5 are standards of good workmanship that can be achieved with normal industry practices. Rather than rock the boat with your QC manager, relax and enjoy the ride because you can't win this one.
