Pipe welding can be demanding and rewarding. We were recently contracted to weld some 3″ and 4″ schedule 80 pipe for a major pipeline company. There were a total of four locations that needed to be completed in seven days. The client needed us to lay pipe to Baker tanks for a nitrogen purge that will pressurize the system to about 1500 psi. All welds were completed with SMAW using 1/8″ 6010 5P for the root and hot pass. We then capped with 3/32″ 7018 ATOM ARC rods.
Although there were many long days, we teamed with another welding contractor to complete the job on time.
