@dicksargent3582 10 месяцев назад

There not " CAST STEEL " they are drop forged. Cast steel is a term for an intermediary process where the original material is cast as a billet and the forged or rolled to shape. It is not cast into a final product such as a frying pan or any other shape. Once forged or rolled into a product or material to make product from it is virtually impossible to distinguish it from other processed steels with any of the methods shown.

@Altair885 Год назад

In the file test, the reason why the file skates over the weld is because when welded with ordinary fillers, the weld pool draws in the abundant carbon in the cast to form a high carbon alloy, this is extremely hard and brittle. It's the reason cast hast to be welded with a filler such as nickel or similar, as these don't pull out the carbon, and that means the weld remains ductile and doesn't crack as it cools.

@rvalcourtpersonaca 5 лет назад

In its molten state cast iron flows better than cast steel. A cast iron piece could be much more detailed than a cast steel piece. In a cast iron part you would see square corners where a cast steel part would have more rounded corners. Cast steel could be used in parts that need more structural integrity because it is more malleable, that would be the opposite for cast iron because it is more brittle. Hope this helps a bit?

Hello i have a camshaft that has two damaged lugs where the cam chain sprocket is bolted on. one has a section missing so needs building up by welding, drilling and tapping. The other lug has a crack from the outside right through to the internal thread. I have welded one before but im questioning my self, did i use an arc welder on the metal cold or did i use a iron fillet or preheat the part first.. is the camshaft cast iron or steel ? and the repair to the crack is going to be the hardest to get right.. should i do an acid wash or brake cleaner to remove all oily deposits , hacksaw a slot then braze the opening or is there a better way ?

Hey Brandon got a question for ya, I need to extend a 3 point hitch lift link on a John Deere tractor. I want to do this by adding some flat stock (using flux core wire)to the existing flat stock used to manufacture the link. What do you think would be a good choice for the flat srock material?

@BrandonLund 2 года назад

@Mixed Up im not up on farm equipment but if you are extending an existing design i would use use at a minimum the same size material if not a little heavier just to be safe.

@Z-Ack Год назад

Hot rolled would be best but cold rolled will be fine.. wouldnt use anything else because youre flux core welding it together.. besides no matter what flux core or material you use the wire wont penetrate that deep so would never be as structurally bonded as if you used a 7014, or some stick..

@WesternReloader 2 года назад

Brandon, I need to repair my Broncos front differential. While in process of re/gearing, adding limited slip carrier, and replacing all bearings/races/seals, I discovered the inner pinyon bearing race/cup bore was 50 thousandth’s larger than spec. The cup/race on previous came out fused to the bearing on the pinion. Meaning it failed so bad that it spun the cup/race in the bore and hogged it out. So I need to weld in filler material and machine it back to spec, which is 3-4 thousandths smaller than the new bearing cup/race. I cannot replace the differential case/third member because it’s a rare D44 reverse high pinion IFS with bolt in axle retainer produced for only model years 80-82. Im leaning towards the case/third member being cast ductile iron (because I know a Dana 60 is made from such, but it could still just be cast gray iron, but I cannot find info on the metallurgy for that casting. Any tips greatly appreciated

@BrandonLund 2 года назад

@R Pierce it's probably ductile or nodular iron. You can spark test a small area on the outside of the housing to find out. Since this is a critical part / hard to replace part I would lean toward tig brazing, building up the bore then milling to spec.

@WesternReloader 2 года назад

@@BrandonLund anyone you recommend to perform this tig brazing in SoCal/ Los Angeles? I have a machinist to re-bore after

@BrandonLund 2 года назад

I wish I did man. It's really not that big of a job just time consuming to do it right. Just some tips to ask when you search around. They should be doing a preheat then depending on how long the shop has been in business, if it's an old-timer he would probably braze it using oxy-fuel. This is gennerally considered the gold standard in my opinion. Oxy-brazing has a real good sucess rate. Tig brazing or stick welding are probably equally as good but all the process (if it's some sort of cast iron and not cast steel) should have some sort of preheat with a post heat cool down wrapped in an insulated blanket. Let me know how you make out. If you have facebook feel free to post your project 👍good luck brother!

I have a strange part at work that we frequently have to repair. It’s a lock rod end that is supplied with an internal locking device for large containment structures . The parts are often stick welded with 6010,6011, 7014, 11018 and even er70s6 mig. Doesn’t matter it always fractures when struck with a larger gamer or sledge. Sometimes even just prying on the locking device causes failure. I was told years ago it might be white cast iron?

Okay wildman... Before you fix that pan with a coat hanger and a torch I wanna know if cast steel and cast iron can be welded together. Using 1960's technology. May have to go run my spark test at night on account of I can't drill a hole, it's too rusty to file and there's no break to look at the grain. There is grain in steel and it will look different depending on the break with or against it. I've seen it look granular like cast iron before. Thanks for your videos and please... I learn as much from watching an error as I do from watching a correct job.

@BrandonLund 5 лет назад

Cast iron and steel can be joined using 1960's technology. Its beyond my time but folks have been doing it successfully for decades. If you have no ability to test your part than you are limited to trying to weld it and hoping for the best. Cast iron can be a crap shoot to weld depending on its carbon content amongst other things.

@BrandonLund 4 года назад

mfdoomgr the short answer is that one is iron ore and the other is steel ore. One of the elements that separates iron ore from steel ore is the carbon content. Iron has a very high carbon content which it’s the carbon that makes cast iron more difficult to weld than steel. Cast steel in general is no different than regular steel. One is formed mechanically while the other is formed by pouring (cast).
