Is it allowed to machine the groove of pressure pipelines on-site using a angle grinder?
Normally, a groove cutter is used; without a supervisor, no one will know whether you have passed or not.
It is possible as long as the welding quality is ensured.
Are there any requirements for this? As long as the groove is prepared and meets the requirements for welding procedure qualification, is that sufficient?
If it’s not prohibited, then it’s okay. .
At the site, many welders use grinders to create bevels; as long as the bevels meet the standards, that’s sufficient
This question was raised due to the emergence of current groove cutters, right? In the past, it was done using on-site angle grinders, oxy-acetylene cutting, and other methods. As long as the design groove requirements are met, it is sufficient. Furthermore, beveling machines are not omnipotent either, and there are many situations where they have limitations.
