Gjutjärnssvetsning alltså

Since it is "just" a counterweight with no need for higher structural strength i would say that it is propably made from grey cast iron and not cast steel.

I would say a high nickel welding material and thorough preheating of the material is a must.

Maybe a used counterweight from a wrecker is the easiset option, keeping in mind that your faulty counterweight is worth a bit of money as scrap metal.

Just try and weld a bit. Let it cool for a day the worst thing that can happen is that it will crack again.

Steg ett måste ju vara att ta reda på om det är gjutjärn eller gjutstål. Vissa kan avgöra det genom att se färgen på gnistorna när dom slipar på det, ett annat test som bör fungera är att borra i det med ett vasst borr - segt gjutstål ska ge längre spånor, medan skört gjutjärn bryts sönder till småflis.
