body and interior Is this repairable?

[tedwardcairns]

I need some advice on the mount location on the hood that I have. As you can see from the photos the metal is cracked in that area and I am not sure with my novice welding skills if I could repair it and have it still shut and line up properly.. and yes the bolt for the hinge is stuck.

Cracks welded, welds ground flat then a plate / patch welded over the area. Patch should not be welded all the way around. Don't attempt with flux core

Give it a whirl.  It's pretty thin material (metric version of 20 or 22 gauge).  Turn your welder (MIG I'm assuming) down to what ever setting is for 22 gauge.  Lower it if you blow through.

 

A butt weld is probably one of the easier welds.  I might be tempted to drill a small hole (1/8th or smaller) at the end of each crack.  Reduces stress concentration factor (I had to look that up)

 

Practice on some scrap.  Novices become experts with practice.

I would prefer to use TIG on that. Maybe phone some engineering shops and ask if they can weld thin sheet with tig. Shouldn't cost much.

Thank you for the advice, I have the budget of a high schooler making minimum wage so I can't pay for someone else to do it. I am okay at welding (got a new trunk pan in and back piece) but not great. I will give it a try and hopefully it works.

thank you again.

Clean, clean, clean, then-

Low power, but high enough to penetrate fully, and if you try a 1/4"+ bead,

blow through. Use small little stitches, even 'buttons' or 1/8" long beads,

moving around the panel so no localized area gets hot enough to warp,

and hammer (and grinder, too) work as you go to keep it flat.

Slow at first, but as you go, you'll pick it up.  The MIG is fine this way.

 

Then free up and oil the hood hinge.

If it gives you trouble, you can strap it on your Volvo and bring it to Kingston for a bit of TIG welding.

You will spend more time driving than we will spend welding, but let me know if you want to come over.

You have been hard at it for some time now and I would be happy to help.

I'll bet we can wiggle that stuck bolt out as well.

The Volvo died and was sent to be crush a few months back now, so it'd be the GMC, and you're right about more driving than welding. I will try to fix it myself, and if it doesn't work I could always find an alternate.

Thank you for the offer though!
