6013 break test!

[Shield Arc]

I was asked to do this test on another site, boy this isn't good at all. 1/8-inch 6013, 115-amps, 1/4-inch flatbar. Broke with about three hits of a 4-pound hammer. Then I separated the two pieces by hand!






Couldn't quite get a full 1/4-inch fillet, so it must be about 7/32-inch.










Top plate.


Bottom plate.

I wouldn't worry about that being a bad weld. It looks good, I don't see any trapped slag, settings for that size rod seem close. The reason it broke so easy, was only being welded on one side. If you would weld both sides I'm sure the result would be different. I use that same technique when I weld a lift eye onto something I want to move, after I have moved it I take a hammer and back brake the lift eye, makes clean up easier on both pieces.

I did the same test with 7018, beat the top plate down on top of the bottom plate, the weld didn't break. Put both plates in the vice, and I had to beat the top plate back the other direction to break it off the bottom plate.

I have always thought the 6013 was more brittle than the 7018. Was the 7018 test brake first hit towards the weld or away from the weld?

 

[Shield Arc]

Hit the top plate on the opposite side of the weld. The 7018 test I wished my son-n-law didn't borrow my sledge hammer, the 4-pounder wasn't really big enough hammer.
Here some pictures of the 7018 fillet weld test.

That's the reason I call 6013 "Beauty Rod"......I'll stick to my 7018 thanx....

Another good weld, and a good test. The results show the differences of the two rods. The 6013 looks good, seems brittle, but I think would hold in most cases. The 7018 looks good, seems to stretch and holds very well. I haven't used 6013 for a long time, we typically use the 7018 on frames, things with vibration, or repeated stress.

Shield Arc, looks like you know what your doing. I always reading your comments.

No, noway, I'm just a hack weekend warrior! Actually my weekends never end, everyday is the same as the last.:laughing:

Retired professional maybe. You can claim hack status all day long, but that won't make it true.

On the other hand, I aspire to advance to hack status someday.

I wonder if a cold/damp 7018 would not have performed similarly?:drool:

I was wondering the same thing.
Many of us here are non professionals and don't have a real rod oven, and the rods may set in cabinets for months at a time. And many use 7018 right out of non sealed packages bought at a big box store or TSC.

Also, since there is a lot said about 7014 and 6011, I would like to see how it compares.

Those were asked for on another site, stay tuned, I'll post the results when I do the test.

Great! Much appreciated. :thumbsup:

Maybe my eyes are gettin bad but the penetration doesn't look very deep to me. Around here you get canned pretty quick if that weld failed so easily.

Granted it's only welded on one side but the root is awful shallow to my eyes, could be the pics...

Also proves the point that pretty welds don't really mean much about the value of the weld.

But ya gotta look good too!

That is a known problem with 6013, it is known for shallow penetration! Why some call it a sheet metal rod.

 

[eastexan]

I worked for one of the largest railroads back in the '80s, and 6013 was prohibited from being used on locomotives and freight cars.

This test proves the reason why.
Kudo's to Shield Arc :thumbsup:

Well it is rated 10,000 psi less than 70 rod, but I wouldn't of expected it to fail so easily.

I rarely use 60 anything, I have some but never had good luck with it. Now I will just stick to my 7014, 18 and 24 with the emphasis on the 18.

With my new to me DC machine, I'm realising more and more that for 95% of my needs, 1/8" 7018 is all I need. It does everything I need it to do and does it well.

Been watchimg this thread, and still dont understand what you guys are looking for! Not trying to upset anyone, trust me, PLEASE! But the harder metals(the weld) will always break easier under impact than the lesser metals (mild steel base, which is less maleable, meaning flexible, do to carbon). Weld both sides and you will swing a hammer till you break the handle. Just imagin if you took a half inch plate and wizz wheeled a 1/4 groove out of it, put it in a vise and smacked it with a big hammer, it would be basically the same thing, but with a softer steel which is a littlle stretchier so to speak, may take a little wigglin to separate. Dont mean to rock the boat guys, please dont take offense! I weld for a living, and im just speaking from experience.

weldermike I know exactly what you're saying. Realistically the test doesn't prove a thing, too many variables, like the amount of force applied by my arm. I just thought it was strange that 6013 broke so easy! But passed a coupon bend test. My understanding of the fillet weld test was just a quick and easy way to see the inside of the weld. I know when Innershield wire came out we had a hard time learning where to set the machines. We used engine drives for power source, with a wire feed. We would adjust the machine to the best of our ability, then run a quick and dirty fillet weld test so we could see the inside of the weld just for a looks see.

Here's the 6013 bend coupons.
