The ball valve passes slurry
and from not being closed properly has some edge damage
The reason for repair is price and availability here in south America.
what is the best filler to weld astm a743 ca15?
preheating or no preheating?
post welding heat treatment?
This is a large valve ball about 80cm in diameter and the weld will be about 10 kg.
Is it better to weld in stages to control the heat buildup?
