Cold stitching is far more reliable for engine repairs.Gents,
A good friend of mine asked me if I could repair his old tractor (Steyr 80 made in 1956).
The cylinder housing cracked due to frozen water. As best I know, the material is 'grey' cast iron. Wall thicknes is unknown, I believe it is somewhere around 10mm or more.
I got some 3,25mm OK 92.58 welding electrode made by Esab, but I've never used one.
My plan is to warm up the engine, then drain all the water. Then I try to preheat the weld area as best i can.. Badly, I have no oxy-acetilen setup, so I can only use a big propane torch.
I can measure the preheat temperature with infrared thermometer, but thats all.
I also have an AC/DC TIG welder, but a welder friend told me to use the electrode as it is.
By the way, the crack is around 60 mm long.
Has anyone experience with such a repair? Do you have any suggestion for the preheat temperature what I should aim for?
Thanks
Cold stitching is new to me, I need to look it up.Cold stitching is far more reliable for engine repairs.
Or Cast iron oxy-acetylene welding - but that's really specialist. Look at CIWS in Coalville.
Brazing but you'd struggle to get the block hot enough i reckon.
I wouldn't trust tig brazing on an engine block but that's just me.Cold stitching is new to me, I need to look it up.
My location is in Hungary, so Coalville is more than 3 clicks away sadly.
TIG brazing could work, but I don't trust its watertight permanently.
I know a man in Ogre Latvia who would repair it, Ramoto Ltd, Juris Ramba.Cold stitching is new to me, I need to look it up.

...you've got two companies that make the bits: Lock N Stitch and Metalock
