Here’s some pics of an aluminum charge-air-cooler, or aftercooler, we cleaned & repaired. This cooler is off of an Epiroc Pit Viper drilling rig. The cooler had some damage to it externally as well as some leaks which we fixed by tig welding. The brackets that had worked their way loose were tig welded back in place as well. There were some cracks that we also tig welded. A pressure test to ensure it has zero leaks & it is ready for another round of service.
