[quote="CVPost-sms"](quoted from post at 08:39:38 12/02/23) I had a friend that had a welding business repair/weld an irreplaceable water pump for me. He preheated, welded, peened to relieve stress and cooled it very slowly over a day or two. It had spiderweb cracks, he got them all and 20+ years later it still doesn't leak.
I don't know what equipment he used, I probably did at the time.[/quote
My go to welder guy for cast welding or brazing too would preheat in an old oven. Along with a metal box of washed, dry sand at the same time.
Take cast piece out of oven and weld it up.
Then set the cast on top of a bat of fiberglass insulation and cover both with he oven hot sand. Then another bat of insulation.
Sometimes it took three days before you could handle the part with bare hands.

This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
