this is amazing but without all that cool equipment, who can do this for the 1 personal headlight repair they need to do? Surely there's a way a DIY individual can repair a single headlight that doesnt require all these special tools and materials?
Is there any reason not to fill in those waffles to increase the strength? Obviously they manufacture these with the waffle to save on material costs, but not sure why one would skimp at this point.
Done properly, this kind of repair doesn't need extra reinforcement. In most cases, it's ideal to try to keep the OEM appearance to match the other headlight.
The staples are just to hold it the tab in place. The putty has a completely different function. The putty is designed to get into those waffles to prevent the welding rod from blowing through and causing distortion. Normally, we would use aluminum tape on the other side of a weld, but it would be nearly impossible to get the tape deep into those waffles and stuck tightly. The putty keeps things clean on the cosmetic side and makes it easier to refinish. The putty is handy on headlight tabs with gussets, waffles, and ridges, which are harder to refinish. You wouldn't need the putty on a smooth tab.
Not unless you want to destroy the entire headlight. The nozzle size is just too large and the heat is not controllable, so it ends up damaging the surrounding area.
@@976charlie9 You can do it without nitrogen, but it cannot be done with a standard heat gun as originally asked, for the reason listed above. By using air, you do sacrifice some strength, but you should be able to build the weld up sufficiently to compensate for that. The heat gun, if like the Polyvance 6055 with temperature control, fan control, and a reduction nozzle will work. All others will not for the simple reason if you restrict the airflow of a standard heat gun to the size needed to weld, you'll end up burning up your heat gun in a very short amount of time.
The shape does remain the same. So, for example, you can use it to take a mold of a single bumper tab and use it to repair several. We've seen someone make a mold of about 1/3rd of a detailed grille and repair the 2/3rds that was missing. You can keep the mold to reuse later if you repair a lot of the same parts.
I don't know how or why I got here, but I have to say: excellent job!!!
Thank you! Glad you stopped by!
Damn that's impressive how innovative this is.
Thank you!
This is very useful knowledge , thanks for sharing
Thanks for watching!
Excellent video and repair
Thank you!
Nice job guys 👍
Thank you!

Once you’ve stapled it I have no idea why you need to use the putty 🤔

How much celsius is heat blower set when welding plastic rod?
Hello. Each plastic has a different recommended temperature setting.
@@polyvance PP for example?
@polyvance as a service advisor what’s the average time our tech can receive to repair something like this.
Depends on how many tabs are broken. I would say roughly around 35 minutes per broken tab.
Can you use just a standard heat gun?
Not unless you want to destroy the entire headlight. The nozzle size is just too large and the heat is not controllable, so it ends up damaging the surrounding area.

If it has a small nozzle? My question is it necessary to have the nitrogen?

Come on it sucks because it stay the same

What stays the same?
