I dont know your application,but in my experience in oilfield production work "Brother-in-law" (one welder on each side of pipe) is used in almost every situation if conditions permit. This speeds up the process and keeps the heat more uniform, I have brother-in-lawed a lot of four inch schedule 80 running frac. and schedule 40 for sales lines, have done this up to twelve inch.
Hope this helps
