Does Welding Cast Iron on Both Sides Make it Stronger?

120 ratings | 2157 views
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.

Thanks man! I appreciate your support!

P.S. I subscribed to your channel
Doug (3 months ago)
ah ok that makes sense. Thanks
Brandon Lund (3 months ago)
Hey Doug, by tapping or peining the weld you are removing any slag that formed from the top of the weld so when you restart the weld you are welding on to clean metal again.

How many times has that pan been welded? I wonder if all those repairs are affecting the irons character.
Brandon Lund (3 months ago)
It's been welded at least 4 or 5 times easily. It is probably weakening the cast but I don't really know to what extent. I'm guessing it's negligible but I'm sure it is still making it weaker.

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 bet that sand actually works very well! I completely agree about your brazing vs welding comment and that video is a good test! Dont go giving my wife any ideas! Lol cheers!

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..
Dave (5 months ago)
@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.

Thanks David! So which machine do you prefer? I'm a Hobart fan myself.

Hey Brandon, you are my favorite to watch. Waow! 114 pounds in the cook pan! Mrs. Lund will be happy. Next year the turkey should be bigger hahahahaha !!!! Thanks again
Brandon Lund (5 months ago)
Minouchat Thank you very much for your kind words! It means a lot! Mrs. Lund needs to stop cracking these pans over my head :)

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 .
Brandon Lund (5 months ago)
I like that suggestion! Thank you. And yes mig up is more difficult but I will see what I can put together! Cheers brother!
Bruce D (5 months ago)
thanks Brandon, keep making your videos they are great,, how about some mig up it is the one position most have trouble with.
Brandon Lund (5 months ago)
Good stuff. Cast rods are usually a good choice and take your time as you found out.

I am amazed the handles of that plastic tote didn't rip.
Brandon Lund (5 months ago)
No kidding! Rubbermaid is good stuff!

Stronger fix by far and using that sand was a good trick , watch out for that gold fever ,you can buy pay dirt on line for gold panning but research the sellers
Brandon Lund (5 months ago)
Yah I can see how it could get addicting!

I've watched all of your cast Welding videos, well probably all the welding vids. I stick welded a cast fire grate with 6013! Cosmetic extension so no weight test...
james cairney (5 months ago)
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.
Brandon Lund (5 months ago)
Thank you for your support! Hmmmm 6013? I'm not sure ive tried that one yet? I may have to give it a try!

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.
Brandon Lund (5 months ago)
I like it!
Weld Weld (5 months ago)
That’s good. If you try it that way you could clamp the pan to the table and hang weights off handle. Be interesting to see pulling from another way like I mentioned.
Brandon Lund (5 months ago)
I like that idea and your comment showed up also :)
