    Hi folks

    new on here and only recently picked up the welder after we got one at work to play with. Been a steep learning curve! Currently restoring my E30 and putting a cage in it (I’m not doing that bit).

    have done most of the seams on the car but does anyone have tips of technique when coming across seam sealer. Trying to get as much out of burn it out but the residue can really mess up the weld with some funky red flames.

    just a few pics of build so far. Trying to do as much myself before sandblast and primer. Chosen the deepest of deep ends...

    Cheers
    Chris

    We cleaned as much as possible off then blasted, I would think to day to acid strip shell before braising seams, always found welding was to hard & they cracked.
    ,It is a pain we tried to get shells on special order without paint, seam sealer, or sound deadening goo.
    We mainly did Forrest cars
    One suggestion is a good Hand wire brush & clean as you go
    Welcome we await lots of pictures love them here

    Welcome to the forum Chris. :waving:

    Is it going to be a track day car, out & out circuit racer or what?

    Cheers folks! Well glad to hear I’m not the only one. Guess I just need to be careful to not blow holes in things, pretty hard even on my lowest setting with 0.6 wire.

    Plan is for it to be a fast road/ track car but built in line with msa standards. My thinking is that if I ever did sell it, it would hold more value than some crappy street cage thing. Unfortunately my ocd gets the better of me with a. Trying to be neat and b. Endless possibilities haha

    Welcome to the forum!

    From my experience, playing with the wire speed can help with blow through at a low voltage setting. ie, upping the wire speed incrementally until you get optimal results.

    Using gas with solid wire can certainly help too.

    I have gotten pretty good at using flux core with no gas, which burns hotter IMHO and have reduced blow through to a bare minimum unless Im dealing with very pitted metal.

    Im no expert, for sure, but the above items have pinpointed trouble spots for me in the past.

    Ah yeah good point, I recently played with this and good better results. Generally speaking looks like if I run a slightly slower wire speed for spotting in a repair patch but for filling say bigger holes or doing a seam then upping the speed gets that material in there without blowing things to bits

    Hi folks, small update and some advice needed. As expected when you go digging you find a heap of sh*t. Trying to be very careful about cutting out too much material when its on the jig for obvious reasons. Recently cut out the rotten section of inner arch to weld in a repair piece. The plan was to leave this open so it could all be blasted but the inner structures just became far to weak so ive had to weld it up. I sprayed everything with a bunch of weld through primer with a view that the blaster should be able to get down the inside after...i hope.

    Anyone got any tips got treating hidden surfaces prior/ after welding?

    Cheers
    Chris

    A few updates, ripped out the seatbelt brace as it was rotten and put in 40mm box. Idea is to tie in the diff through the floor as from experience getting to those upper bolts is a cock when removing the diff. Also started arch destruction then my welder died

    Looking good. They've gone up in value so much recently it's worth doing a thorough job.
