[MW:27249] Welding GS-45 cast steel (modern equivalent GE240 / 1.0446)

Hello,

we have an old machine part with two 28 mm keyway slots ground out due wear. We need to fill up those key ways and machine new slots but due to construction limitations any other methods such as machining a replacement bore insert are not suitable.

Slots are approximately 36mm wide, 7mm deep and 140 mm long. The bore diameter where they are located is around 140mm. So far we have received mixed opinions on weldability of this material: one slight "yes might be doable with correct procedure" and two "DO NOT WELD IN ANY CASE!!!"...


So do any of you have good guidance on suitable welding procedure for cast steel GS-45?
Best regards,
Mikko Laine
