How to remove a small bit of powder for repair work?

[julianf]

A friend has this -

It's the top of a tent type thing (yurt-a-like)

He has just had it blasted and powdered (against my recommendation but it's his life!) and then managed to fracture a few of the small pipes which he now needs fixing.

Which I can do fine, but not whilst it's covered in plastic.

I'm going to get him to clean it up. My best guess was to heat it, see if the powder would scrape off, and, if it didn't scrape off, carry on heating and turn it to ash, and then get a wire wheel on it...

Or incinerate it and then blast the area (as in small area).

I plan to reflow the fractured joint with Tig, as I'm more competent with Tig than mig and can control it all that much better. I'm never expecting a clean weld.

Is this as good a plan as any?

And, specifically, any better ways of removing the powder?

A wire wheel or fleece strip wheel like above is more than enough of remove powder coating. There’s no need to burn it, that’s just just more work and more damage to the surrounding coating.

Thank you.

I repaired something like that for my niece a while ago and the metal is very thin, you need some low amps to do it. It breaks next to the weld due to the heat input.

 

[julianf]

Yeah, it's the metal next to the weld that's torn. It's just rubbish from China.

If I do it with Tig, aside from the lack of cleanliness, I'll have good control over the power.

A yurt? Does he weave his own yoghurt?

A yurt? Does he weave his own yoghurt?

The other side of things.

Used to work for CISCO. Quit, bought land, bought cheap from China yurts, takes money off London yoghurt eaters.

Not that there's anything wrong with eating yoghurt, mind.

A yurt is just a yoghurt without the ogh grasshopper

Decent powder coat I've had to remove required an angle grinder!
