There are plenty of pipelines currently being built all over. I bank a pipe coating company that that is on fire. 1/2 of the welding will be done by OilStates or LaBarge. Its called double jointing then it gets coated and truck to be welded in the field...this lowers the risk of bad welds.
There are not enough welders and the folks doing these jobs are hispanic. I know because I tour the fab shops here in Houston. They are paying wages as high as $32 per hour and that is high for Texas.
My neighbor works for a fab shop and he said that they told him that they were going to 12 hr shifts 6 days a week and he told them he was only good for 50 hours, but then said the hispanics would never leave if they would let them.
There are lots of jobs...folks just don't know how to do them or are to good to do them.
