Is plasma cutting a mechanical processing method?
Thread Content
According to the standards for boiler installation, mechanical processing methods are recommended for cutting low-temperature nickel steel and alloy steel. Is plasma cutting considered a mechanical processing method?
In that case, how should the φ377*20 12CrMoVG material be cut and processed on site?
Plasma cutting is possible, but the hard, brittle layer must be polished clean after cutting.
Please advise: how to determine whether the \"hard, brittle layer has been polished clean\"?
I think the wording should be “cutting using gas cutting (or plasma), and then using a beveling machine (or milling machine) to create the welding grooves” – in that case, how should the φ377*20 12CrMoVG tubes be cut and prepared on site? – There are small machines for cutting grooves at tube ends as well as machines for cutting grooves at the edges of plates
