Magnafluxing- interesting "how it's done" link

Saw this when I was looking around about the Magnafluxing process to look for cracks and such. Thought it was interesting and wanted to share:

That might be a cool tech article or something. Let us know how it works out.

 

Mag particle testing is used to detect indications open to the surface or slightly subsurface. Liqiud penetrant testing is used to detect indications open to the surface only. LP is more sensitive for finding tight cracks. the MT process requires the operator to us a blow ball to remove excess powder, takes getting use to. you can use a yoke, like the above operator or they have machices for the coil method and the head shot. Another way to go is to perform an LP. With this process you clean the area, apply penetrant, remove excess penetrant and apply developer. the developer draws out the remaining penetrant from any open indication, red dye, white developer, called color conrast Lp. MT is more forgiving as far as surface condition and temperature but the equipment is more expensive. Buying LP material and following the instructions on the can is easier but a little more time consuming.

 

I've seen parts advertised as having been Magnfluxed with one seller offering to supply a Certificate of Magnaflux Inspection. Unfortunately for a buyer, he was careful not to state whether the part was cracked or not, only that it had been mag'ed. Cute, but no sale here.

 

I guess I don't understand what you're after here? Are you trying to find information on the Magnafluxing process? We've got a wet particle Mag machine at work with a 12" hoop. Works great for cranks and heads and the like. We've also got a portable Mag for cylinder blocks and things. I've got some literature if you're interested.
Someone asked about casting flaws. Casting flaws or "flash" can look similar to a crack with the wet particle Mag, but with practice you learn to spot the difference.

 

shucks...now everyone's gonna know that magnafluxing a head isn't rocket science after all! just put the magnet on it, flip the switch, blow some powder, and see how it looks...then move to the next area.

 

I just picked up a motor and need to get the block and other components Mag'd, but then realized I didn't know much about it, so I started pokin' around here (didn't see anything) and around the web. Just thought I would share that link. Never realized how simple it could be and/or how complex some of the related processes can get. More info would be great just for an education if you would like to share, but ultimately I just thought it was interesting and wanted to share with the HAMB in case someone else was wondering too.

Sooo.... post some info if you got it! Might as well keep building up the library around here! Would be great if this place became a "one-stop-shop" for information some day!

Cheers!
