Hey schwag,
IMHO, I'll attempt to give you a brief summation of what I would consider a person who is classified as a "Master Welder". After welding 43+ years in SMAW, GMAW, GTAW, Plasma, O/A, Induction, and Resistance, tool & die making, machinist(cnc & manual), Production Design, Fabrication, and field("on-the-road") experience, I couldn't make a pimple on a "Master Welders" butt.
A Master Welder would deserve that title:
1.) Proficient in all the above processes and the newest ones.
2.) Experience in rig, structural, pipeline, aircraft & aerospace, underground, underwater, vessel, automotive, marine, food service, shop & production, rail, bridge, platform, and can pass every test required in a heartbeat.
3.) Has a degree in Metallurgy & Engineering.
3.) Worked over 16hrs non-stop, in a smoke-filled environment, 100+deg., -30deg., in a thunderstorm, inside a confined space, 200+feet above ground level, 200+ feet below ground level, 200+feet underwater, hanging from superstructure, upsidedown, welding with a mirror, and all with wearing the necessary protective gear.
4.) Has a family, home, & all those responsibilities.
5.) Never gets upset with the job, co-workers, hours, duties, time constrictions, and especially quality.
Now, there's a brief of the title to be earned if there is such a title. I know others here will include all I have missed to make sure the title is justly accurate for that moniker---Master Welder. If the title can be had in 40 years....I will salute & bow in reverence to be sure......Denny
