Hello zincsvtcobra, I believe you could receive any number of responses to your question. I believe geographical area will have a great influence on the answer. Union vs. non-union will certainly make a difference in many cases. Type of industry and application for pipe welding could play a large part: process piping, pipelining, in-shop pipe fabrication, onsite fabrication, steel or exotics, I believe you get the idea.
You may wish to be more specific as to your locality and your specific target(s) as to type and application of pipe welding. There are folks who frequent the forum from all over and of a vast array of applications. They can likely provide more specifics at that time. Best regards, Allan
