![]() ![]() Because that metal is so thin, I just had to keep it in movement all the time.Īnd lastly, I ended up around the engine, where some components were already missing, but I obviously cleaned up the inside of the engine. I had to bring down the values a little bit. For steel, I go up in the settings, and usually I run them at around 80%, and aluminum I run at 60%.I really noticed along the body panels, I have to be very delicate. So if I'm cleaning aluminum, I will bring the settings a little bit down, because aluminum is softer and it also has a lower melting temperature. So with all these settings, I can vary or adjust the laser beam. There are exactly four settings on this machine that I can manipulate: the first setting is power, the second setting is frequency, the third setting is the speed of the laser beam itself, and the fourth setting is the width of the laser beam. Once I finished up with the wheel hubs, I actually moved on to the muffler that was on the other side. You do not want to keep it too long at one certain area or on one spot because you can damage the metal if you keep it on one spot for too long. So you always want to keep your tool or your handheld gun in motion. You can damage the surface substrate, which is the metal. With any laser-cleaning machine, this is a beam of light, and it also creates a lot of heat. So it's either or, right? And that happens within milliseconds… nanoseconds. Either that, if it's not the pressure or the heat, the laser beam itself will vaporize the substance on top. Once it touches anything above the metal, the heat will actually remove the contamination on top of the metal. So everything above the metal surface will actually absorb the light of the laser-cleaning machine. ![]() The metal surface is the last resort that will not absorb any light. Once it's pointed at your work piece, it will resonate with the contamination on top of the metal surface. Once its frequency is established within the laser source, that will be emitted through the handheld gun. So how does laser cleaning actually work? So the laser-cleaning machine has a certain frequency. It cleaned up the threads on the hubs themselves. I was really surprised that it cleaned up everything. Once I was done with the fenders, I moved in to the wheel hubs. And that's where it will rust, because the water actually doesn't evaporate or go away, it just hides behind the fender. Right around the fenders it rusts because you have, all the time, water splashing up on the fender. That was just my thought process, it can be in any other order, but that's just the way I do things.Īfter the wheels were clean, I did the fenders themselves. So the most outer parts of the car I wanted to clean first, and I was going to work my way in. I'm taking away quite a bit of rust that's been built up for over 40 years. After that I grab the handheld gun and I get to work.Īnd I started off with the wheels. So I will be wearing a mask and I will be wearing laser protective glasses, just to be safe. Once I have all the settings set up, I will put on my protective gear. The next step is actually just to prepare the laser-cleaning machine. It's really important to know where the rust is building up and which direction it's going in to actually address it with the laser cleaner. The first step is just really visually looking at everything. And I would like to remove that, so I can bring this car back to running conditions and also make it somehow suitable for the road. And especially on the underside or around the wheel wells, you will see quite a bit of rust. Looking at the Renault R5 Le Car, the body work is still very straight, but around edges it does have some rust. If you have parts that come in that are just full of grease, full of oil, just full of any surface contamination, you can actually use this laser-cleaning process to remove all of that. And this handheld device will always be pointed towards a metal surface with any surface contaminants. Laser cleaning is a process where a laser beam gets emitted from a laser-cleaning machine. And I will be cleaning 40 years of rust on a classic Renault Le Car from 1979. It often indicates a user profile.Īndreas Yurich: Hi, my name is Andreas Yurich, on social media I go by Workshop Rebuild, and today I'll be sharing with you guys the laser-cleaning process.
