Right - doing a Baxter and decided to get myself a MIG welder. Not used one in a LONG time and even then it was brief.
I'll start small (plenty of practice on scrop metal) but want to tackle my rear arches.
Have just sourced from rear arches for me 3 door nova (small standard arch panels not full 1/4 panels) but need advice on best method to use.
The main issue is do I butt weld or lap weld new panel to existing panel?
Figure the following is about right so far -
- offer up new panel to old one
- draw round edge of new panel onto old one
- cut round edge drawn (perhaps leaving a little extra on below drawn line)
- undrill spot welds on sill (no inner lip so no spot welds there)
then do I lap weld or butt weld new panel to old one?
How do I anchor it to keep it still long enough to put tack welds in place.
Know I need to use grips but where do you anchor them to?
- once thats solved I need to bead the entire edge to join fully
- attach to sill using drilled hole in new panel and spot style weld through hole to sill then to new panel.
- grind down excess weld
- skim, seal etc...
The bit in red's the bit I aint too sure about.
Also - how to do you guys tackle the inner arch when theres no inner lip? Do you build a new inner lip and weld to old one, then spot style weld to new outer skin?
Please post up your tried step by step processes. Add any pics or other advice.
And no - I wont take it to a body shop - none near me that are free at the moment and I need to teach myself. Spent enough last year getting all the structural welds done properly - figure the none structural ones I can do myself - there's plenty of other litlte none structural areas I can get on with before starting on the arches.
