Does material lose strength when flame-cut?
Does material lose strength when flame-cut?
(OP)
At shop we flame-cut plates with our CNC cutters.
At sites, to correct mis-fits we flame-cut pipes and plates with oxy-acetylene torches and proceed to weld them.
Inspectors reject whatever is flame-cut at sites, but for some reasons they dont question our factory procedures.
Why is that?
thanks

RE: Does material lose strength when flame-cut?
Agree with gtaw that it is probably a visual rejection based on the way the flame cut looks. Field cutting is usually done with expedience....with larger tips and higher oxygen pressure....just to literally "blow and go". You might want to specify or suggest a smaller cutting tip to give a "finer" cut appearance.
