Are you sure you want to be pipe welder? I know the money is good, but after working with all the different types of metal and welding processes, you will be staring at 6010 all day every day.
I am the welding development consultant for a natural gas/electric utility. Obviously we have plenty of pipelines but also piping in the compressor stations and at our Nuclear facitilities. Our sizes range from 36" down to 3/8". We use both company employeed welders and contract welders (which you are talking about). For the contract pipeline welders we pay 42/hr labor and 14.90/hr for renting their equipment (57/hr total). For the pipe indoors (building trades pipe welder) we add 6/hr to the labor but they use our equipment, so there is no rental fee. We contract from local unions and from out-of-state. So there is usually a lot of travel or at least will be at slower times for you. I qualified a pipeliner last week who was in Montana, Mich, and Texas within the last 10 months. Not all have to travel. Anyway, you will probably not recieve any offers unless you join a union. You will probably recieve apprentice pay for the 1st 4-5 years regarless of experience to become a journeyman. We will pay journeman money to an apprentice if they are qualified to sec. 6.3 of the API 19th., and we get written approval from their union rep....doesn't happen often. Building Trades welding is much more versitile, different alloys, processes and such without as much travel. Just a little input. Thanks
