To deviate a little. Here is something else one can make out of rebar.

i guess I've been lucky. I've picked up rebar scrap for years and never had a single issue welding with it...ever..?? and I'm certaintly no pro welder.. nor is my ac buzzbox anything special..

Soundguy I have never welded much rebar at home, but on the job I don't even want to think about how much I've welded. One time in Alaska 7 days a week 12 hours a day for 7-weeks!

There is more to welding rebar than the average guy really knows, generally the bar will have a "W" on it.

TSC has weld on stake pockets, weld on tie downs and chain pockets etc...

What about AW Direct? They have all sorts of stuff like this.

i'm planning on making a knife and a small hatchet with a hammer hear rear out of 2 railroad spikes I have. just waiting for some spare shop time.

the diagrams look pretty and all.. thanks for posting them.. however.. my previous statement remains unchanged. I've yet to -ever- come across a piece of rebar that I have been unable to hotglue to another piece of metal.

One thing I have NOT done is weld rebar to rebar. I have welded rebar to mild steel, ( hot and cold rolled as well ) to cast steel, cast iron, and some forgings. all with about the same results as I would expect welding a piece of hot or cold rolled or mild steel bar stock or round stock to those same materials.

can't even begin to imagine all the tractor 3pt upper and lower 3pt lift arms I've seen with a rebar grafted onto them after a bow or break. I've always treated them like mild steel, and just used a 6011 and turned the amps up.. sometimes I dress downt he ridges with an angle grinder right wher ethe bead will be, depending on what I'm welding to or for.

I'm sure what you say is true and there may be some hidden science behind it.. but all I can think is I've been lucky.. every time.. nuttin I've made with rebar has come apart yet...

Soundguy,
You've "welded" rebar to cast iron??? No offense,but its really hard to believe that it held any load at all.What kind of rod did you use?Do you mean brazing by any chance?

Wow the knives are cool. I like em. By the way, I guess sometimes ignorance IS bliss, cause i made two rings from some rebar this morning and they wleded to the frame just fine.

Let me ask you guys another question,
My trailer was used to move grape bins that weighed 1,000lbs each (2 of them on the trailer) and thats the heaviest this trailer will move. It's a heavy built 4ft by 8ft trailer. My MF1010 might get a ride on it, but it might be too short for even the little MF. What size chain would you use for a safety chain. I have some length of 1/4" on hand, no idea what grade it is though.

Should I use heavier?

I have to agree with ShieldArc to some extent on welding rebar with any 60XX series rod. The welds will be very brittle with this rod. They dont tend to bend any at all, just catastropic failure when they let go. MOST rebar will weld with 7018 or higher rod and the weld produced is more malleable than the 6011-6013 welds and more accomodating when welding rebar with high carbon content. There may or may not be any difference in chemistry of W grade rebar. W just means it was tested for carbon content and meets the max allowable for carbon. Generally anything with more than .04% carbon gets very brittle when welded and is more like spring steel than mild steel after welding due to the carbides formed during welding which makes them very hard. It acts like spring steel also in that it will hold till it snaps, no bending is usually evident in the break. The higher carbon content in rebar makes it an exceptional material for hardening. I have made very good center punches from rebar by just grinding a point on it and tempering it. they are better than any store bought

5/16" grade 70 chain is sold for tie-down and is the minimum accepted by the CA Highway Patrol. They require four tie-downs (at the corners). Check your state's laws.

Usually you can by bags of the chain at discount auto stores or big box hardware stores.
