If the head of the bolt doesn't interfere with anything on the other side, I'd drill the plate, put the bolt through, and tack the head of the bolt like in the video. Then the weld is just preventing rotation like a wrench, not taking the entire load of the bolt.

Pretty slick how you tested those. In my younger years I tried welding 1/2” round bar for dowels to a piece of 3/8 plate for my homemade press brake, and they snapped off at the weld instantly each time. I was using a Millermatic 130 with preheating and post heating. I even beveled the dowels and multi passed em. The welder just didn’t have enough ass.

When preheating using a standard MAP/Propane gas torch for that very reason, obviously too little heat has minimal benefits, but is there a limit of too much heat that is attainable when using small MAP/Propane torches. I think it would definitely be easy to change the properties of the base metal like Annealing or Hardening (and rate of cooling/quenching) at critical temps?

The problem with this test (at least) is that the least the handle of the ratchet wrench and the bar are in line, the smaller the leverage on the torque gauge thus the bigger the error in the measurement. To fix this it is best to ensure that the handle of the wrench and the bar are in line.

The test isn’t designed to be accurate to the ftlbs, it’s designed to be comparatively accurate to itself. I actually tested a straight one vs the one in the video and they were almost identical on a torque wrench calibrator. The reason it’s bent is because I had an issue with the straight one running out of travel room unfortunately.

@@makingmistakeswithgreg Firstly, I would like to apologize as most likely my explanation is unclear due to my lacking language knowledge (my native language is not English). So back to the topic. I do understand that there were limitations but what I tried to explain that due to two factors these series of measurements are very limitedly suitable as comparison between themself. Factor 1: Because of the angle between the bar and the wrench handle this measurement setup is sensitive to the change of the angle of attack (I believe this is an aviation term, I don't know if it is right here). Basically what I wanted to say is: Your leverage is from the slot in the bar to the end of the wrench handle. A force exerted in an angle of 90 degrees to this line will create the biggest torque that force can create (on the slot of the bar). For the sake of illustration lets assume that between the bar and the wrench handle there are 90 degrees (they are perpendicular to each other). In this case if you exert a force perpendicular to the wrench handle (parallel to the bar) you will get torque on the sensor but not on the slot of the bar. If you exert force parallel to the wrench handle (perpendicular to the bar) you will have torque on the slot of the bar but not on the sensor. An uncertain amount of angle will create an uncertain amount of sensitivity to the angle of the force. Factor 2: As far as I was able to determine, the angle wasn't the same through the series of measurements (see Factor 1).

Excellent test & video! This is similar to what I have planned to test with my boys (13 & 14yo) to highlight the different processes; although I think a more consistent/repeatable test (flat plate) might be more instructive. Related to this test/discussion, & previous comments..... I often use TIG & 309 or 312, depending on the situation, which has worked very well, in many situations. However, last year I was adding a 17-4 PH stainless extension "clay spade" (the spade is hard/high carbon) for a rotary hammer, and initially chose TIG/312, which welded beautifully. The joint failed, & it busted right through the weld. In the next attempt, I used ER70-S2 & it has survived (so far). I'm still not sure why/how that happened. Sorry for the long comment, but thanks for your videos!

That’s awesome you planned on doing some testing with your boys, that’s the fun part about welding 😀. It also shows that cut corners and poor welds aren’t strong lol. That’s Interesting that the 312 failed. If both welds were the same size with same prep, it’s hard to say why. 312 actually has quite a bit of ductility, although er70 has higher elongation in test results. It could be a simple case where the slightly better ductility of the er70 was enough to make a difference. It could also be a issue where the weld reacted with oxygen with the 312 and produced undesirable defects (carbides, poor grain structure, etc). I rarely weld 17-4 but when I have I used 308 filler and a preheat based on thickness. I have never had a 17-4 weld crack on me, but I haven’t welded that much of it lol.

@@makingmistakeswithgreg 17-4 welds excellent with 309 or 312. In fact, I broke a Chinese made 3/4” breaker handle (attempting to disassemble hydraulic cylinders).....so I machined a piece of 17-4 for the 3/4” driver, & then used 309 to join it to a 2" piece of scrap shaft that conveniently fits inside of a 12Ft cheater pipe. I've put a tremendous amount of force on it, & the 17-4 head and the 309 weld have held up great so far. Back to the clay spade joint: I really believe that something in the clay spade steel made the 312 joint brittle; but the prep was different as well. I had originally machined M/F matching tapers, to preserve alignment. On the ER70 joint, I added weld to the spade portions, then drilled/tapped to accept a 5/16" bolt in both sides (for security and alignment). Fully welded from the bolt out to the 1-1/2" diameter. My boys really enjoy welding.....I just thought the testing of different rods/processes and their strengths would be a slick way to trick them into learning something...😉 They're at the tender age where learning, best occurs when they least expect it. 😂

That definitely could be done, the one issue it could present is the bolt is pretty small in diameter. Welding directly to the the shank will affect the strength of the bolt far more than welding to the head. The head didn’t get that hot but the shaft would get red hot welding on it due to a lack of heat sink. When I grab a shop press I will have to screw around with a test to see how much a difference it makes.

Greg this was very interesting. One thing I fould was to use a dissimilar metals rod. I was making my own ficture clamps and welding high tensile shoulder bolts to the clamp bases. Two very different metal compositions. I used a rod we have in Canada called Extreme from Air Liquide a welding metals manufacturer . This rod is designed for welding different metals and I believe the tensile strenght is over 70,000 psi. I leaves a bead like 7024 but is all position. I am sure there is similar rods available in the US which you could try and see how they preform in this test with mild steel and grade 8 bolts. again great video Greg.

Without a doubt you are onto something with that idea. My preferred method on this task would be 312 or 309 stainless with tig, it would likely exceed the performance of the methods I used. They do make stick rods here called “the problem solver” that are variations of 312 stainless. They are incredibly strong and not susceptible carbon pickup (which causes the weld to be brittle).

Many years ago we had a situation on a structural steel building frame where we had to weld A410 high strength bolts to beam flanges, through trial and error we determined that a preheat to 250 degrees C and the use of 312 SS rods was the best expedient field method. Great video Greg, as per usual.

The method using a preheat and 312 makes total sense to me that would have came out as a solid option. The 312 can handle a lot of carbon absorption without becoming brittle, it has a tremendous tensile strength near 110K with a yield near 80K, and it is well known to handle welding dissimilar metals. I have a stash of 312 tig rod and it can be a life saver. Its cool to hear actual testing that showed the validity of 312.

You indicated with the flux core mig with a preheat might work.

Their 7018 prime is my go to 7018, the rest of the other ones are ok (the atom arc is pretty good). I wonder if you bought their retail packaged one.

Hello Greg, very cool Video! I guess that brittleness would be the enemy to adress prior to total strength. I think that every hit on the anvil would create a sequnence of very hard an quick pushs and pulls. With the given limitarions I would give the plate a preheat of over 130°C (hoping it stays straight) and use shortarc MIG (or even self-shielded flux) in 2 passes. With a stronger welder i would try one hot pass with approx250 to 320 Amps and no or just slight preheat, depending on the type of steel - for Europe I guess S235 or s355 for the plate).

Great thoughts. Flux core wire tends to be brittle and has limited ductility. It’s actually fairly well known to have failures in high impact force tests. That is why they make specific flux core wires for high impact toughness requirements, and other specific uses. The strength of the flux core is good, but I don’t believe that welding bolts to thick plate (like in the video) will be possible to do with porosity free welds due to how the process works. Even if the surface is clean I would highly suspect internal porosity. Obviously the test did not cover impact testing, but a fairly brittle weld (made worse via absorption of the bolt alloy) combined with even a small amount of porosity would have to be a 100% recipe for failure with a impact.

I always stumble over the differences in standards between Europe and the US. For a application like this i would use 12.9 bolts cause of their high ductility (I personally know these from agricultural machinery such as plowshartes where 8.8 would schear of or break in a matter of minutes to few hours) but i dont think it's a good idea to weld this kind of Material. Drilling through the plate, countersink the holes from the back (would leave about 8mm of Material) using allenkey-bolts and bolted down from top with nut and spring-washer would do the job. To lock the bolts in place i imagine one could use Cusi3 (is it siloliconbronze?) to prevend the bolt from spinning and avoid creating a creepy alloy. It is way of the given prerequisites - just my thoughts.

With regard to weld strength, when welding something that requires better penetration or joint strength, can Beveling one or more of the surfaces improve joint strength/penetration similar to like they do for thick plate or pipes and Hooks do. Sometimes, I think it could be very beneficial to grind even a small bevel when joining thicker materials, especially on welding process with low penetration like MIG or 7018 etc.
