I need to rectify a casting @ 100mm thick with weld buildup @ 100 X 100 X 25mm localised area.
The MOC is ASTM A 148 Gr 90-60 which is a high strength steel casting having UTS: 650 MPa.
Does anyone have any exposure of welding such castings.
Is ASTM A 148 Gr 90-60 a weldable grade and welder friendly ?
What should be the preheat and interpass temp.
Can i get some technical literature on weldability of ASTM A 148 Gr 90-60.
