Only weld top of the nut on rebar not bottom too. Going to pound in set here at house and head popped off rebar. Thought it was a fluke, grabbed another and it broke as well. Lesson learned rewelded a couple with same kind of nut 3/8 down from top and no problem. Oh boy, 140 more to fix. Sometimes more weld is not good

CAN`T WELD " POT METAL". LIKE THOSE CHEAP CHINESE JUNK HAMMERS AND AXES( AND RE-BAR). BEST BET IS NO WELD, JUST BUY NON HARDENED NUTS, SLIP OVER TOP AND LAY ON RR TRACK AND HAMMER THEM SIDEWAYS. NEVER COME OFF, NO HEAT SO WON`T MAKE YOUR RE BAR BEND LIKE NOODLES, OR SHATTER. i DON`T THINK YOUR PROBLEM IS THE WELDING, IT`S THE "POT METAL" IN THE STAKES

DON`T FEEL BAD. i DROVE 18 MILES ONE WAY TO SET UP A DAMAGE JOB. OPENED UP BACK OF TRUCK AND GOT THE PICK AXE AND CHIPPED OUT 2 SETS. PUT PICK AXE BACK , THREW 2 TRAPS AND STAKES OUT AND LOOKED AND NO BASKET IN THE TRUCK. HAD TO DRIVE 18 MILES BACK TO THE HOUSE AND THERE IT WAS AT THE BARN DOOR. DROVE THE 18 BACK, MADE MY SETS , THEN 18 HOME AGAIN. SAW GREENFIELD 4 TIMES . IWAS DEBATING HAMMER THE TRAPS IN WITH A ROCK, MAKE FLAT SETS WITH MY HANDS AND LEAF PAN COVERS AND PEE MY OWN MAN PEE ON THE BACKING. THEN THOUGHT, NO JUST GO BACK AND GET THE GEAR.

If you peed on that flat set probably be coyotes waiting in line to get caught. I've got 100 to fix yet. Probably fix them the way you suggested.

If you let it cool slow it will do better. You can even heat the nut and weld back up with a torch and slow cool (anneal) for better results. It you quench the weld it will crystalize and break easily. Even welding on good metal then cooling too fast will break.

the nuts? yes cheaper the better ( softer). all the farm stores have bins of them. 5/8th on a 1/2" rod works great. hit them 4-5 times not real hard works better than bust the bank heavy 1-2 hits. tell them you do NOT want hardened nuts. lol, nothing worse than hard nuts.

Guy told me to take my stakes and put them in a fire and get a glowing red hot. He said let them cool down on their own and they might be OK. So I got them glowing red hot yesterday let the fire go out and I tried them out this afternoon. I tested 25 of them and none of them broke. I'm no physicist but it's something to do with the carbon molecules being able to re-bond Seems it worked

I was ready to redo them but I figured I could build a fire& let them glow red awhile. Next time I make some though ill use a anvil instead of the welder.
