I know this is some years older. I've done my fair share of automotive weld repairs. Bolt as much as you can to the mating surfaces to the broken piece weld as much as you can with its mates bolted on . This will provide the best fit going back together. I've learned this the hard way. You don't want air leaks and warped flanges.

I seem to recall that 5356 is frequently *not* recommended for parts that will see sustained temperatures above 150 deg F. It seems that 4043 is generally better for underhood parts, at least in this regard.

This is an old vid but for any new watchers you can see if it's aluminum or magnesium by wetting it with vinegar. Magnesium will react aluminum will not.
@patricklindholm67888 жыл бұрын
You mentioned getting rid of moisture with the pre heat of the aluminum. At a AWS meeting this last winter the topic was hydrogen cracking and they explained heating the material just opens the pores and drives the moisture in to the material.

How do you determine if its aluminum or magnesium? Both are non magnetic. Some older VW beetle crank cases are magnesium, some were aluminum. How to tell the difference, also, can you tig magnesium?
@xtal5675 жыл бұрын
Eccentric Smithy magnesium burns. Aluminium melts. Watch ave vidéo about it. Vinegar also reacts with magnesium castings.

Any other set up spec on the welder for us, pps, hz sounded 130ish, modified wave, background amps, ar/he? Why would you run %70 balance when you guess the casting to be dirty, why not run 60/65, or is that where you found it doing best? Been struggling a bit myself with some dirty welding 1/4"al with a dynasty200. Thanks
@Welddotcom8 жыл бұрын
hz = 120, no pulse, 100% argon. The cleaning action will vary a little bit. That is why we like to run a test bead before welding on the actual casting.
@Welddotcom8 жыл бұрын
Pulse is related to amperage. For instance if you have your machine set at 100 amps and your pulse at 1 pps / 50% background current it will go from 100 amps to 50 amps and back to 100 amps every 1 second.

Thanks. I wonder how if you are still using your regular ck worldwide 17 flex torch and how it was coping with the extra amps, or was it a ck26?
@ralphwaters89054 жыл бұрын
The single red hose looks like a #17 air-cooled torch to me, so 160A is all he should attempt. I would bet he was running close to a meltdown at 200+ on this repair. I have a water-cooled CK FlexLoc torch and it has 3 hoses: black (gas), blue (water in), and red (cable & water out).

Next time you have to grind on aluminum have some bees wax and touch tthe turnin burr to the bees wax now and hhen. The bees wax will help to keep the aluminum from sticking to the burr. You will have to clean the bees wax from the al before welding.

Good thing that u didn't use a good lens for the camera , even in cast that welding was useless. All I could see was bad stacks with no penetration , try using a Speedglas in future to show the actual truth
@mrmidnight324 жыл бұрын
Kinda why I never liked Mr.Tig. I always felt like this dude would lie to your face about something. No way he uses that scrap alumi just to show him it’s not the machine. Get the setting dialed sure but we all know if the camera wasn’t on he’s fire away on the piece as soon as he got the setting right, not show him self his machine isn’t malfunctioning and that the casting is dirty. Even as a relatively “new” welding we all know castings are nasty af. Such a dumb excuse for a lesson to be “extra safe”. It’s like teaching someone to check every fire extinguisher and fire alarm in the warehouse each time you start to weld. No one does it and it’s a dumb thing to lie about. That’s another reason I love Bob and the guys, they tell it like it is honestly no BS.
