I think you are a good teacher. You do a good job explaining things. Too often teachers get caught up in the industry nomenclature and don't explain what things are, what things mean and how they relate to each other. I am someone who is interested in learning to weld but have only laid a single splattered bead with a stick welder 30 years ago in Jr. High School. If I were to get serious about it I would like to learn from you. Nice job.

I like it a lot when a credible guy from a welder manufacturer explains things. The other KZitem teachers out there are ok and say similar things, but it's better to drink water directly from the well with such a tricky topic. Nice work, please keep doing these.

Good little Video. I just Welded 2 Cast Iron doors on a Furnace . Been Welding since the early 70s. I always use a air power needle gun. The old guys that told me said it helped to stretch the metal better than a hammer. I'm sure both ways are right. Read the mag. from cover to cover. Still working and welding and still really enjoy it.

outstanding! had serious doubts you could pull this off with that much porosity in the parent material and with cast being very specific with how you deal with it but the end result was beautifully done

Good explanation as to why a 7018 weld is likely to crack with castiron

Some of the great issues in welding are being addressed here! Welding cast iron seems like a problem for generations, and also the use of preheat, which nobody wants to do. I've watched a few hundred welding videos and maybe four of them involved preheat! Seems cheap and easy and solves a lot of problems apparently. I'm getting a definite impression that any weld is a good weld on cast iron if it doesn't crack. If it looks scarred that might be just fine, who wants to grind off such expensive welding metal anyway? Gives the thing some character.

That is a beautiful weld, more so because of the difficulty.

What happens if you run it hotter than about 900 F ?

I guess I am just lucky. I welded a cast iron post puller and it came out stronger than the original.

Are you allowed to grind the weld flush or does it have to stay that way for strength? What if it must be ground down for clearance?

Would love to know this also. I assume if you did good layering you could grind it down... I’m about to do this on my cracked dawn vice

A year ago and no reply. Must be off welding some where. That do you think? It probably depends on the application. are aesthetics or health concerns eg a food processing plant . Could it be welded on both sides ? Many variables. Actually if I remember right a little bit of stress is relieved when you run the grinder over it.

One of the trickier materials to weld --- options are limited (SMAW w/ nickel ($$$$), Oxy/A brazing ($))..........................
