Stumbled across this on another forum, looks interesting. Had not looked into the cost of equipment yet.

 

Pretty cool. Looks like they stay back far enough to keep from warping the material.
Just think how many trunk lids might be saved. Interesting to say the least.
Thanks for the post.

 

It looks pretty easy, there is also a system for aluminum and other materials. Have not found a cost for equipment yet.

 

It's gotta be lead, or some similar soft metal.

And that was filmed in the UK or A-NZ, so it may be unavailable here.

We are a world wide economy, don't you pay attn?

 

Yes, but there's not a world wide EPA.
Yet.

 

There is a distributor in Washington state.

 

when I worked for gm the hot sprayed silicone bronze on the roof to quarter seams in place of the lead

 

I think that only applies to employment (or loss thereof...).

Body shop friend said the silicone bronze mig stuff is the thing. Haven't tried it yet.

 

silicone bronze is amazing. We outfitted a welder at work to used that wire which just requires straight argon gas vs a mix. But welding seams when replacing quarter panels is a breeze specially when you butt weld stuff like quarter panels and patches etc etc . No warp and you can pretty much just lightly grind the weld and file it down.

We just got a pro spot welder so we can now weld on quater panels just like the factory does with resistance welding.

i also agree this has to be a soft metal alloy.

 

it's probably zinc (or a mix) and it's been around in the US for many, many years already. There was/is a place that used to advertise in Hemmings or some other car related venues and they called it "spray welding" or something similar. They were trying to sell franchises.

 

Wonder if it would work on pop metal?

 

There's another method used by some to repair pot metal....a product called "Muggy Weld". Another mix of softer metals but with a much lower melting point than pot metal itself. It's a stick form and you use a torch to melt and apply it. I have no idea how well it works or holds up but it's also been around for many years.

 

This is called flame spraying and the technique has been around for decades. It is primarily used to build up worn areas on industrial equipment. The concept uses either an oxycetalene flame or an arc to melt the filler metal (which can be almost anything) and compressed air to spray it onto the part to be repaired. The filler can be either powdered metal or a wire feeder like a MIG. If strength of the repair is important, the part must be properly heated. There are a number of companies who do rust repair on sheet metal this way.

 

I'm surprised this has been around for decades, You would think many more cars could have been saved over the years. Especially up here in Canada. I've never heard of the method posted.
Interesting.

One site I went to said they started in 1922. That's awhile

I seen one of those machines. I didn't see it in operation.
