I used to program and run water jets and that is actually a lower temperature then what a water jet would run at. Cutting parts with friction using water and sand makes a LOT of heat. After cutting a sheet of parts the pool would be around 130 degrees or more and the part would be even hotter then that. After they got a large water cooler to cool the water in the pool it dropped the temperature of the pool down to 60 degrees but still it makes more heat then people think it does, especially with thicker harder objects.
I used to run an FLOW water jet and it's hot towards the end of the day. Usually 110-135 degrees. The water jet is better if you are cutting thick material or if you are cutting different kinds of materials.
yes and no. the plasma arc is over 25,000 degrees and does in fact heat the kerf as it cuts just because you quench it quickly doesn't mean that you don't have a heat effected zone. try running a drill bit through a mild steel hole that has been plasma cut and tell me that it wasn't hardened. you just not heating the whole plate but the edges of the plate is most definitely harder and thus more brittle than if you water jet cut them. temperature tests mean nothing do a Rockwell hardness test on your edges if you want to know the truth about how you effect the steel.
Plasma has its place, just like the others. One note though, plasma limits you usage to one media where waterjet for instance lets you cut anything you want with the exception of tempered glass.
and its completely obvious that these people work exclusively with metals. if they were cutting other materials they would use different tools and machines.
i am very glad i watched this video. i have been wondering how i was going to shape the ar500 plates i have in the garage without a waterjet or some crazy diamond or cbn saw. i always wondered if precise plasma or laser cutting of ar500 would actually work without destryoing the steel. i still would like to see controlled ballistic tests however.
jordan secrist - I never had a chance to do any scientific testing but my targets are in use at 3 commercial ranges two police academies and hundreds a personal sales as well as my own range and never had any problems or complaints so there were no need to do any scientific testing. I have seen edge damage on plasma, water jet and laser with a bullet strike so in my non scientific opinion it really does not matter
The HAZ (Heat Affected Zone) can be measured in thousandths to large fractions of an inch depending on cut process, metal thickness, rate of travel and time. There's no way to get around it, it can only be minimized. Using a hacksaw wouldn't give you an HAZ but it's boring. The major component you are (almost) eliminating is warping of the material being cut. I'm sure you can measure it in microns but I doubt you're looking for that degree of flatness. I've flame cut AR500 then conventionally milled milled it to make it look professional and it did BAD things to my bits while making the blank round or square but once thru the HAZ it milled just fine. Oh, by the way, I got my metallurgy thru a multi year welding apprenticeship program where I welded on nuclear, pressure vessels and structural. My tests were X-rayed as well as destructively tested and improperly tempered welds (bead placement, HAZ) would fail the destructive test by either breaking or the metal would form lesions in or around the HAZ welded portion of the test coupon.
What was that measuring metal out in the sun supposed to prove? That made no sense. The middle of the plate isn't going to have a HAZ, its right at the cut. To know how thick your HAZ is you need to polish the surface, etch it and look at the crystal structure under a microscope. I agree that Plasma's probably the way to go for this application. a temp gun isn't going to tell you how thick it is.
Hey there, thanks for the video. I run Mach 3 on my CNC plasma table and I'm thinking about cutting out some of my own plates for Target practice. What amps are you using? I see you are using 65 amps at 45 in per minute. Also did you have any angled cuts with your machine? What plasmacutterr we're using?
Showing that the heat of the sun is more than cutting with your setup doesn't prove that the metal isn't changed. That's idiotic. All that proves is that the temp is lower. All it can really show is that at the metal would be more brittle at the point where it gets cut. Why? Because in the sun the metal will get heated from the outter surface inward and cooled at about the same rate. Keeping its integrity better than a super heated very localized area.
I doubt the heat of the whole plate is what people are talking about. Its the 1000+degrees that the edge is taking as its being cut. Cutting under water would make it even worse on hard materials your essentially quenching the edge as it cuts. Do that with 4140 or something hardenable and is guess you could make a nice knife out of the edge lol. I wouldnt worry about the plate for shooting tho just thought this was a pretty dumb video as far as breaking any myths goes. Cool plasma tho i stumbled on this looking for a home use plasma table
Water has very low thermal conductivity and has little effect on the heat affected zone, which is determined by the plasma settings necessary for an acceptable cut, and to some degree, by the thermal diffusivity of the metal itself, which is much higher than the water. The water merely protects the operator, shield the UV to some extent, and acts as a reservoir to cool the plate, perhaps slightly faster than if it were sitting in air. The water also differs from air in its chemical reaction properties with the plasma cut plate.

Interesting facts here. Who makes this stuff and Id love to here their video response of this video. Would you do a SIDE hit video on a plate such as this? Im looking for some how to vids on welding this stuff to if you know of any
Hello BriZZell, When you say who makes this stuff do you mean the targets? Or who makes the steel? We make the targets from steel that is sourced from US foundries. AR500 steel is a common grade of steel and is available from steel suppliers across the US. As far as a side hit video Its tough to hit the edge accurately at distance. I can try going out to the ranges that use our targets and take pictures of plates that have been in use or months and years for comparison. As far as welding AR500 plate its possible but not recommended. The heat from welding will definitely affect the hardness and in targets its best to avoid welds because of the impacts you will useally see cracks or failures along the welds or in the HAZ of the weld. We try to design all of our target systems without any welds on the AR500 plate.
Who makes AR500?.. is what I meant. I'm looking to make a structure that is bullet proof - but saying that is so not good nuff. What we think of when someone sez bullet proof is not the reality. First off the structure is not disposable and will be needed after gunfire not replaced. bullet proof in this case means handling one or two clips from a few AK47's. non absorption of the rounds is a good thing which is unheard of elsewhere. I SAID CLIPS! BITE ME! lol
You can get AR500 from nearly any metal supplier. I use 3/8 AR500 for my targets it stops and shows no damage from nearly every pistol round and also .223 5.56, .308, 7.62 x 39. The plate usually only shows damage if people are shooting the plate very close with those rifle calibers. Normally if the bullet is traveling less than 3000 fps at impact there will be little to know damage. 5.56 and .223 up close will slightly dent the surface when shot very close 15 to 20 yards but it stops it with no problem. Armor piercing rounds and larger calibers like 338 lapua and 50 cal can pierce the 3/8 plate but they do make thicker plate. Bullet Proof is dependent on the bullet. Pick what you want to stop and then design from there. 1/4 AR500 plate would work for all your common pistol rounds.
15 feet away, concentrated fire (3 foot spread), three 30 round mags. .Perps using a 223 5.56 or 7.62x39. 8x17x8 foot box. don't even have a clue how to budget for this.
i don't think your measurement is that accurate going through water, what emissivity exponent is the device set to? those temperatures are way too low to do anything to the steel's microstructure. if you do have some heat effected zones it is probably so close to the edge it doesn't matter for overall target strength. generally to get brittle steel you must heat it up to transition then quench it quickly. not sure if that process happens here. other than that, heat it up and letting it cool slowly results in more of an annealing, opposite from brittleness.
I agree it was not the most scientific of experiments but it gives a lot of people the general idea of what it taking place and what measures we take to minimize the heat affected zones on the plate.
can anyone demonstrate why the worry about the so called weakness at the edge of steel that is cut due to heat? when an item is fully fabricated and on the machine steel will break at the weakest point, if the job is engineered properly heating the metal at the edges is of not worth the worry over nothing.
I also built my table with candcnc...and also am using a H65 cutter...where did you get the cone on your torch to limit the water spray? something you made or found as a dual purpose?
The splash guard is actually a rubber drain stopper from Ace Hardware. I have put a link at the end of this comment. I just cut out the center with a razor blade so it is snug on the torch. I works to keep the splash off the components above and it also works as a soft bumper for pieces that flip up. www.acehardware.com/product/index.jsp?productId=1273002
I wondered that..kept thinking, what around the house looks like that because it seemed familiar..funny..good idea. I designed a laser center pointer for the machine torch that I had wanted to integrate a deflector.. I'll look into it..thanks
I've done this many times....... We cut out 1" AR plate for bench rest silhouettes on a vented system (no water at all). Over time; these things get shot thousands of times and you can tell no difference between the center of the silhouette and the heat affected zone, from projectile impact. The myth is just that; a myth .................

I have ran all three machines for decades. I dont know what you are trying to prove here? I have cut AR plate on all three machines. About 400 holes in each plate 60 by 50 inches. On the laser the plate warped by about 1 and a half feet. On the plasma cutter about a foot. On the waterjet machine no warpage. Your high tech thermo tech gun making two cuts on steel! Wow!

The sun's atmosphere is about 500,000 kelvins, 900,000 degrees Fahrenheit which is way hotter than any Plasma machine lol. The sun's surface temperature, which is its "coolest" layer is 5,778 kelvin (10,000 F) The sun's core is 27,000,000 F, which is15,000,000 kelvins!
We have found that every cut process will "nick" on the cut edges water, plasma, laser. Water jet is most expensive process followed by laser then plasma. In all the testing we found that the HAZ really did not matter and what really matters is price for the customer. So plasma wins for overall cost per piece.
it is stupid to compare plasma and laser for the HAZ , temperatures are high on both on the cut zone (and around it (few mm- as heat transfers trough metal materials travels faster) but that heat transfer is exponentially lost that is why you don't melt 1cm in diameter but 1mm. laser is far more precise but for thick (more then 0,5mm) metals it doesn't do shit of difference, as it needs power to melt trough it and the same power is used as with plasma and the same transfer of heat is done just a tiny bit faster. HAZ you may get on the edges (in a 1-2 mm at worst) and that is true for both of the methods. rest of the plate is more then safe ... so all in all , that HAZ thing about cutting is bullshit. If any of you went to proper technical school you would learn about "materials" and their properties ,and the curves for changing crystal structure of metals ... en.wikipedia.org/wiki/Steel - learn about heat treatment section
