Weird weld

The tapered drift pin might be a chunk of oil hardening tool steel or some other weird mix. The rebar is either .4% or .6% carbon steel. You welded it with a lo hydrogen mild steel rod. I have no clue what the metallurgy of your weld puddle or HAZ would look like.

If you need to do it again, try mild steel rod, heat soak the result.

Your rods are wet.......

Oh, and so is your innershield wire.....

So is your brain. What was your point?

Dry your rods.... ;>)}

I live in the desert southwest. At any given point, my rods are drier than

I'm sorry if your reading comprehension is somewhere hovering over Cleveland right now,

The point was, and I am terribly sorry that you missed it, that two VERY dissimilar metals were being welded together.

But, you, in your immense body of welding knowledge knew that.

Right?

No?....................

Maybe? ..................

Um .....................

errrrrrrrrrrrrrrrr........................

ARGH!! I meant to say "mild steel rod instead of the rebar". 7018 is a good choice of rod unless the pin is some really exotic alloy.

Let me say this about that ................. It was hard to see that the welding rod was sticking to either ..................

Steve

Ohhhhhh, you got the REALLY high carbon stuff!!!

Let me put it to you this way .................... It was one hell of a weird puddle ......

Steve

Whatsamatter steveb, is your brain roasted in that desert heat? Better get _yourself_ wet.......hurry.. ;>)}

No, it is much easier to just hit this button here, and .......

poof.

You are gone.

At least until you morph again. Which could be twelve seconds from now..........

sigh .............

I'm sure others will weigh in, but rebar has always acted funny to me. Cuts weird. Welds weird. Exfoliates like crazy when bending, even hot. Just weird. I always figured it was made with the left over scrap and slag that wouldn't go in anything else.

For home quality yes. The junk kind.

There is rated - specified - used in highways, runways, large buildings and the like.

While most at HD or Lowes - and most metal places is the cheaper scrap steel. Sometimes strong. Never shatters.

It is a hit and miss with junk stuff.
