durafix easyweld

[brightspark]

having bought an aluminium casting from autojumble the slot in it was 2 large for purpose i clamped a couple of washers on either end with molies then put in vice . a quick clean up of casting with stainless wire brush then heated with small propane torch .touching metal with welding rod to see if its hot enough on the second touch it was hot and started to flow then i sratched over the weld pool with stainless rod which made it flow the full distance .hole filled i squared it up on miller re cut tapered slot filed a slight dovetail in it job done . heres a few piccies of it a simple piece any engineering types know what its for il post the article in use after someone gueses

Does it flow like water.?

I did a few patches on my trailer roof with Alumaweld. Should be very sililar. Works well but difficult filling a vertical tear on my metal roof. Too hot and it dripped down.

Have tried it on engine casings and it takes a lot of heat. Even with a MAPP torch took several minutes to get the rod to flow, then a cold weld unless you get it considerably hotter.

I find it is great for things like you did. I use it often on stripped threads. Drill lager and tap it considerably bigger. Then fill and re-tap.

Have also used Burnzamatic rods. Works similar but the filler seems lower quality.

Looks good.

yes it did flow like water ideal on horizontal surfaces but wouldnt work on vertical surfaces. i think used with oxy acetylene it would be more controlable rather than heating the whole job up in general though good stuff with a bit of practice

i take it that no one knows what the casting is used for

great job! nice to see it's being put to good use....

Seen a casting like that but can't for the life on me recall where. now that is going to drive me mad...

casting

heres the casting and what its used for

Well I've never seen one of those. What's it called. Rufforth find was it?

We run a aircraft company repairing microlight ultralight and would like to try your durafix

You made a grand job of that................. would a toolmaker use a file with a handle like that?

I tried durafix or similar rods. I got nowhere.

The melting point of the al is so near the rod its very frustrating, most of the time it never flowed, and the al collasped in a puddle.

I'd give it another go if I used a digital thermometer, and a flux.

Not where i come from.



Kind regards,

I'm quite tempted to cast a few of those, just for the hell of it

I have used HTS-2000 Great stuff, but as has been said, you needs lots of constant heat. Oxy-act would be best for localising the heat instead of mapp etc heat loss.
