Burning magnesium is as bright as a welding arc. Steve S It's brighter in my opinion and Damn fast. Long time ago someone used my bench grinder on some mag part they thought it was aluminum. I used grinder next as soon I touched that piece of steel to wheel big bright whit flash erupted inside the ...

Great info. Oh, and BTW, challenge accepted! :twisted: Thanks. Confused on the challenge part, do you mean about collecting tig rod to be able to weld anything. As far as the 318 tig rod it does exist. Do not know actual uses for it just googled it Lincoln PDF link http://www.lincolnelectric.com/as...

If you wouldn't get so rowdy when repairing cases, a fire extinguisher would be a non issue ;) Sent from my SM-G900V using Tapatalk Not a matter of being rowdy just paranoia with old age I guess in case something out of the blue happens. Its some of the small mag parts that bother me the most. Figu...

here is some thoughts on using stainless to weld steel 1. can it be done=yes 2. should it be done=NO and yes :? DEPENDS what does this weld do? Your best bet is to match your base metal as best you can except when you have to use a different filler to achieve desired properties out of the weld. Best...

Thank you Airrj for the info i appreciate it. Especially from someone using the stuff to fight fires. That F500 stuff is pretty cool never heard of it. apparently it can be used in an extinguisher. Found a video where they show how to refill and charge an extinguisher with F500, however that video d...

Want to add a class D extinguisher to shop just in case. Deal with magnesium cases and parts with would like to have something better then a bucket of sand. Unfortunately class D extinguishers cost a small fortune, but still cheaper then a fire out of control. Anyone have one in there shop curious a...

adrynalinjunkie I suggest turning up heat in garage to 60 to 65 degrees several hours before you do your welding. General rule of thumb if air temperature is under 60 degrees warm the tubes up. If you warm tubes up instead of turning up thermostat just use a propane torch don't need anything extreme...

ER70-S2 gives better elongation than ER80-D2. Most chassis builders in open wheel use ER70-S2 allows chassis to deform more as car takes multiple hits from flipping. Some do use ER80 either for certain areas or whole car. Your case either one will work just fine. don't burn up the metal and don't fo...

Oh by the way the grinder sits right along the OA unit. The company has managed to install cameras everywhere because they fear employees might be slacking off for a few minutes here and there so the boss watches them work. Its pretty pathetic. Forget safety expense worry more about bottom dollar or...

And be careful with those pressure cookers ! And slippery shower stalls ! And angle grinders too ! A wire wheel can fly off the bench grinder, go through your eye and penetrate your brainz( small target). Stupid kills. Yep at times people need to be told that. Guys at that shop should be afraid of ...

Have you approached your boss regarding the problems, that being the poor condition of the equipment and lack of training for the current users? Point out a new oxy system and training is cheaper than an ohs investigation and dead or burned workers. Thee owner is the boss and he sees it as costing ...

A place I do some work part time at has a OA unit that scares me to point I will never use it and they know I refuse to use it. The regulators are old never been rebuilt the gauges don't work, hoses have little spider cracks the entire length. The employees that use it have no safety training using ...

@Poland308 I ran Knoxville, I love that track doesn't really feel like a half mile due to straightaways being kind of short but has wide sweeping turns pretty fast track. Got to visit there hospital one night. First time I was at a hospital where most of the emergency section was closed off for the ...

By open wheels do you mean sprint cars? There are three classes Midgets, Sprints, Champ Cars (Silver Crown they changed name but for us old racing families and old guys we still consider them champ cars) I don't consider minisprints as one of the classes they are not traditional and fairly new plus...

@greintime
Open wheel cars it's easier to come in from top of cage forget snaking threw side plus there was a midget and Sprint car driver that had one leg. He wore a device on upper part that was left it locked into special pedal built into car. Very good driver and hell of a nice guy.

I could not tell you exact alloy. I will offer what I would prolly do in your position. For cast aluminum I typically use 4043 for repairing engine cases, differentials, transmission cases and such. I find the added silicon in 4043 helps with the crude in the cases. I might preheat the whole thing i...

I've seen a US vendor's site listing both Chinese and US made ( Sharon Steel ? ) 4130 , I can't remember the name. Yes it is common for US suppliers to have US, German and Chinese tubing available. Always have to pay more for US and German steel. Plus pay extra for certs. My concern is as cheap as ...

I thought post weld heating was a thing of the past for most people that are welding 4130 in motorsports applications after Senior died. Sent from my SM-G900V using Tapatalk Never known or heard of any open wheel chassis builder to heat the welds like they where doing after welding going back to tu...

I wouldn't put to much stock into finch in my opinion he would have you sanding copper off every pieces of ER70s or ER80s out there :lol: He has several books in his name all with same stuff under different titles. Think it's home depot or Lowe's welding books, or at least that's some of them. 4130 ...

Anyone using the new Docol R8 tubing in place of 4130. I'm not totally sold on stuff curious if anyone has experience with it. If you don't know what it is this is a general idea of it, 4130 is a heavily alloyed metal that relies on different added metal to achieve the desired strength's and propert...

I would bet your whole problem can be solved by arc length. Get that arc length small and tight and I bet it goes away. Long arc length equals more voltage which increases heat too. Do a couple of short welds concentrating on arc length if you think it's right you prolly are not close enough. Be car...

This isn't a welded today but welded before Christmas. My wife is impossible to shop far. So instead of buying her anything I made her something that she has been looking for and cant find. For years she was looking for a stocking holder that holds more than one stocking. The stuff in stores is pret...

Have some repairs coming up on truck tool boxes. From research looks like most of these are 5052. Repairing original spray and pray mig welds that didnt penetrate and cracked. I was gonna use 5356 but debating about using 4943. Anyone used 4943 on 5052 thats been in use for awile. If so hows it hold...

When ever anyone starts out on aluminum they want to baby it which as others stated is the wrong thing to do. Mash the peddle :shock: you will get a puddle then will have to wash it over to other part. Which ever part has the best ground is the piece the arc will jump to. After puddle formed you nor...
