What is a ballpark estimate of touch time for this repair? Not counting cool down times or flash times of some steps that were used? For this particular headlamp, what would you guess was the actual repair time spent on it? I am a high school auto body teacher and am talking about repair times with my classes, this information would be great to add to explanation. Also, I was able to purchase one of the polyvance nitrogen welders with table this past school year.
It varies depending on the complexity of the tab. Waffle tabs take longer than flat tabs and ribbed tabs fall somewhere in between. I would say touch time can be ballparked to somewhere around 1 hr average to get it looking OEM. However, bottom tabs can be done MUCH quicker because you don't need to make look pretty, just functional; probably 15 minutes for those...most of that time is spent doing prep work.
Yes, the Nitrogen temp is well over the melt point of PP. It has to be in order to transfer enough heat to the rod to melt it....just like welding with an oxyacetylene torch is way over the melt temp of steel. The nitrogen temp is roughly 900°F (482°C) before it exits the heater but in that 1/4 in between the nozzle and the substrate, the temp drops significantly.
@@scottb7600 Thanks Scott, useful information! Couldn't find any Polyvance video wherer whole tab is welded back (base is broken off at the edge of headlight), is there any? It requires heating from both sides before sticking it back, looking for a safe way to do that.
No, we don't currently have a video like that. If you want to send some pictures of your damage to info@polyvance.com, someone can get back to you with suggestions.
The video is geared more to the professional, but if your headlight costs $2000 (and there are a lot out there that do) buying all the tools to make the repair would be more than worth it. Plus, you'd have the tools to repair a lot of other things made of plastic.
Blown up my mind with quality of repair and video.
I have a different plastic welding setup, but you did a good job here. Looks really nice.
Thanks!
Excellent repair job and excellent video as always
Awesome video
Thank you!
This is amazing 👍🏾
Thanks for watching!
That was very interesting thanks for the demo!
Thanks for watching!

Looks like the repair will cost more than a new headlight? hahahahathe final job was amazing.
Newer headlights can be surprisingly expensive! A shop that can repair headlight tabs can pay off the machine in just a few jobs!
Good

What temperature are you running with your air welder? Seem pretty hot welding rod like this, way over 160C (PP melt point).

This is great but not for the regular DIY guy considering the amount of stuff one has to purchase for a 1 maybe 2 time fix.

I dont have any of those tools. Prolly cheaper if i just buy another headlight
I need for my car
