/diy/ - Do It Yourself

Is there any advantage to or modern application of oxyacetylene welding? Or is it simply obsolete?
Also, is there any advantage in industry to stick arc welding over flux-cored arc welding? I am being taught stick welding in a trade program and my teacher couldn't really answer this question clearly, sort of insinuating that it is rarely used nowadays. Wind resistance for outdoor work is the only advantage I can think of, and even then, flux-cored welding gets around this issue as well. Even as a hobbyist or for artistic applications, I have a hard time understanding what the strengths of these two methods would be in comparison with the other methods.
