Does Welding Cast Iron on Both Sides Make it Stronger? Lets find out! We recently repaired this broken cast iron using a flux core welder and flux core wire. For that repair we welded it on one side and then measured t's strength until it broke. But what if we welded it on both sides. Would it be stronger? That's what I wanted to find out. We repaired the same broken cast iron again using the same flux core wire and flux core welder, except this time we welded it on both sides and then tested it again to see if welding both sides makes it stronger or weaker. I was not expecting the results of our test.

just a question, but if your kinda like tac welding it together (on off short burst heat) wouldn't that be like leaving idk what to call it but lets say contamation on the inside where u cant see like when u hit it then stop hit it again in the middle of that process would there not be contamation because its not say a solid weld as if u just went from one side to the other? but I know why u didn't cause of heat I'm just curious if theres a difference.
Nice test, cast iron repair is often hit or miss, my sand mix is black thermal sand for packing stoves etc, sort of close to casting sand, I think (personal opinion) is that we often think we have welded cast iron, but in reality, we have "brazed" it, and a brazed joint is stronger when brazed all round. Over here in limey land, in the North East, we test our pans (skillets) in the traditional way. https://www.youtube.com/watch?v=hiKEgdQTCEo
I am not going to enter because my OLD Lincoln 225 burnt up and all I have is a Hobart 187 now. Anyway I like all your videos because you are never to old to learn something. Thanks Brandon for another good one..
+Brandon Lund For work under 1/2" steel The Hobart 187 work great. But when I am over 1/2 inch steel I prefer the Lincoln 225 (OLD VERSION). The Hobart has to work it's butt off to keep up with it and gets hot. I put a new improved fan with more CFM on both welders and it helped a lot. All my welders and plasma cutters run 240 volt. ALso the Ingersoll 7 hp air compressor.
when I fixed my vise which was broken in two I beveled all edges and welded with pre heat to 400 f and used 3/32 arctic 90 cast rods with pulse stick 90 amps dcen 3 passes and then cooled over night on the wood stove which I let go out . in the morning cool to touch and no cracks and the vise is back together and working fine. so cast iron can be welded quite easily by anyone if they just follow the technique .
Haha, only rods I had, too inpatient to wait 24hrs for the nickel rods. Just started welding this year, evening mig course completed. Bought stick as I want to be outside more than in. Got a climbing wall to build out of scaffolding poles. If I knew what to do I'd post a pic of the grate but Im not that techie.
You should do one with the pan upside down so when the weight is on it,it actually has to pull apart from the weld on the bottom of the pan because the way it is now is similar to a cardboard box, open on top so you could put your hand on and pull one side away , if you know what I mean. 👍left my comment on other video hopefully it shows up.
