This manual is intended as a guide for field welding and cutting cement-mortar lined and unlined Ductile Iron pipe. For welding or cutting special lined pipe, consult the pipe manufacturer.
Welding is a very important fabrication method in modern industry. If an alloy can be welded successfully, its usefulness is clearly enhanced. Ductile Iron can be welded successfully to produce welds that have mechanical properties comparable to those of the base iron. As with any base material, the success of welding Ductile Iron depends on suitable equipment, correct procedures, qualified welders, and effective quality control procedures.
Remove the pipe’s asphaltic coating on the area where the retainer ring will be welded with a solvent wash or by burning with a torch; then grind the retainer location to bright metal
