I dont know if it is aproved but I do know it is used. Many years ago I went for a job interview. The company was laying 12 inch pipeline on the ocean floor. they would take and 80foot section of pipe clamp it into a machine the machine had three mig welders 120 degrees apart. they would run around the pipe and then it was inspected and if it passed it was sent down into the water and another piece was put in place.
