how durable is a base weld along an edge?

post #1 of 5
Thread Starter 

I got a small core shot right along an edge the other day along with a few other gouges. I took it to a local shop and made sure that they were going to base weld it with metalgrip. I got my skis back today and the repaired area was not even with the base, it was sunken in a bit even with a base grind. I scraped the area a little bit with my fingernail and was able to scrape the repair material off very easily. It doesn't seem to me that it will hold up very long. How durable is a base weld with metalgrip?

Sounds like they didn't use metal grip.  You shouldn't be able to scrape much off with a fingernail.  Ideally you would want to weld a softer layer of ptex on top of metal grip as well.  Proper metal grip is very durable.

I was able to dig 90% of it out with my fingernail. Screw the shop, I have a bunch of stuff on order to do it myself after practicing on some old skis first.

I use metal grip followed by regular ptex ribbon (not candle). My understanding is that metal grip alone is too soft.  My repairs look like crap until the next base grind but they hold.

there's different brands of MG - I use Montana right now, and have used Wintersteiger in the past.  Both of these are very hard  in my experience, compared to any other welding type ptex.  The reason for welding a softer ptex on top is for better wax absorption and less friction.

 

For best results - i take down the bulk of the repair with a 4" panzer or body file when cooled, light sanding to finish and preferably a stone grind.  

 

Key to MG weld is to make sure the area is perfectly clean, and not to apply too much, press it flat with a ptex roller or metal scraper when hot,  and don't repeatedly reweld the same weld with welding iron - reheating previous welds burns the original weld causing it to micro bubble in the weld area.
