S ome repairs, whether it is repairing a failed weldment or repairing a crack in a casting, may easily be done by simply grinding out the crack and applying more weld. Other repairs, however; are more complicated. Or at least they should be. Just last week a customer contacted us asking for help in developing a repair welding procedure for a damaged (cracked) truck frame.
A335 P11 Welding Procedure Chrome Moly Pipe Welding A335 P11 Welding Procedure. A335 P11 is an alloy steel code issued by the ASTM (ASTM). The nominal component is 25Cr-0.5Mo. The mechanical properties of P11 alloy steel tubes are of great significance to ensure the safe operation of chemical plants, especially to the stability of high temperature and high pressure pipelines in petrochemical enterprises.
