Hard face welding for rock crusher

- A basic demonstration on how I do hard face welding and the equipment I use. I'm in SW Florida at strip mine, the rotor needs some love. So I will apply hard face rods in critical areas.
This is how I learned to weld,
our family had a mine outside of Silverton Co. we spent the winter months repairing and maintaining our equipment.
I drew the (lucky) straw to reface the anvil in the jaw crusher because I was a skinny little shit and could get down in there much easier,
To this day. I still do hard face jobs on buckets, blades, scraper bowls etc. Good video!
Stay safe my brother.
"It don't matter, this ain't structural" true, BUT you should take pride in your work.
A friend of mine asked me if I could do some hard facing with my everlast welder. Great video.
Hardface daily on a rock crush just like this one and pulverizers, buckets and such. we use Lincoln Wearshield ME and seems to work perfectly. Nice video ....Makes me feel like im at work Lol.
Bad ass welding machine. Thank you for showing, great welding.
Bad ass expensive machine doesn't mean bad ass welder
I'm not a welder but found this very interesting. Thanks.
+Gun Collector007 Glad you liked it.
Learned a lot thanks
Stoody has a great hard facing product I hard face everything I can on my equipment dozer blade grouser bar excavator bucket the rods are a lot cheaper than replacing parts.

Is 31 the same as 7018 rods
You should invest in a wire feeder would cut your work time by more then half.
Hi David ! Greetings of the day. Great informative video. I am being advised by Castolin to use 6327 XHD and the base rotor metal is Mild steel. I am bit scared if it will work. Advise please.
How much did you charge?
Unobtainium,Must be a fan of George Knapp. Coast to Coast AM.. great vid.
Unobtainable D1.1 certification cause they cant weld straight to save their life
Hi, is there a specific hard facing rod for specific base metals to be used, and where can I found them, or any welding chart/ guide for using a variety of rod and base metal, and what . TnX. Ed
Outstanding!!!
How much do you charge for that kind of job...?
What's a good hrly rate to charge? I want to get into the hard facing game locally. So if I understand correctly. Use 7018 for buildup, and final pass with a hard face rod? If I were to MIG this, what are the recommendations for wire type and size for both buildup and hard facing? Just fluxcore?
Does the metal need to be clean before hard facing or does it really matter?
No because you hardfacing isn’t meant for penetration it’s meant for build up.
@@danielledarke7249 Thank you
Thanks for posting. I suspect I'll be asked to do some hardfacing work in the future so I've been studying. Hardfacing alloy is very hard, which means it's not ductile, and it usually cracks in various ways. It's normal for it to crack. But, I don't see any cracks in the material you've laid down, so I'm puzzled.
How do you like that style of stinger I always use a 300 amp tweco but have always wondered how those do I do a lot of quarry work and scrap yard welding in nc
+Brendan Ricks That stinger is okay, but it gets hot hard facing, some times I keep a bucket of water near by and drop it in. That's about all I use this one for. I prefer the tweco style, easy to change rods. When I can find them, I like those ones pipe liners use.
how long does the hardfacing last For Typically?
I have to reapply the hard facing every 6 months, with them running 50 hours a week.
did the exact same thing over the weekend but used stoody 35. looks like you too got what looks like porosity holes in some of the welds, I couldn't seem to get rid of them. anything you noticed?
I've used Stoody 35, good stuff but prefer the 31. I don't worry about porosity, its not structural just build up and protect the wear surface.
Yeah, porosity happens... Maybe the metal wasn't clean or windy. Doesn't really matter, it's not structural, just protecting the surface.
What's the difference between those stoody rods and a 7018 I'm doing the same thing at work on a hazemag, and they got me using 7018, then going over the top with some e-309
7018 is for welding parts together, like pipe, structural steel or generally anything. 7018 can also be used to build up material before hard facing. E309 is for joining steel to Stainless Steel. Best to use Stoody 31 or 35 and the bigger the better, I like 3/16" and run them around 225 amps.
+David Spin it's actually pretty common to use 308/309 as a hard facing rod especially in remote locals where other hardfaceing rods and wire are hard to come by most of the materials that give hard facing rods their desired properties are in 308/309 rod/wire
Unobtanium?.......sounds hard to come by.
No preheat? Postheat?
I never preheated with these rods, no problems. Don't build up more than 2 passes other wise it peels off base material.
Also if youre blowing that fan right on the arc your going to blow the shielding away
Rough as guts job I would not pay for it
No preheat... a lack of pride in work...
Cold lap... lack of penetration.
Youre really going to take a paycheck and feel proud of your work? Come on bro.
Get it together.
