This automatic pipe welding machine based on the Bauer process, a patented application of gas metal arc (GMA or MIG), can be adapted to all position welding on laybarge, rack or cross-country pipelines. The machine has passed an acceptance test of 10 successive API 1104 quality welds on each of 12, 10, 8 and 6-inch diameter pipe, all with schedule 80 wall thickness. On the basis of the testing results, an estimate of welding rates obtainable with this type of welding equipment on conventional barges has been prepared. The slowest welding rates recorded during the acceptance tests conducted at Sciaky Brothers' plant in March 1973 were taken as the base rate for the automatic welding equipment. This base rate assumes that the end of each electrode used is clipped prior to each pass, that two fill passes are made simultaneously on pipe diameters from 16 through 24-inch, and 3 fill passes are made simultaneously on pipe diameters of 30 through 60-inch.
