Helloooo...

Cheeky post really, I am doing my sills soon, and as their brand new, oridgal sills, I in the understanding, I can spotweld these

I was wondering, as my mig welding isn't the smoooooothest.... can anyone lend me a spot welder?


I don't need it yet... in a couple of weeks I will thou... Don't mind paying for the use either

drill holes in the sill and weld thru the holes. This is known as plug welding andwould have the same effect as spot welding.

MOT passable like that?

I am right in thinking, as I am replacing panels to orginal spec... I can spot weld right?

yes allowed to spot weld original panels on just bare in mind how many spot welds are on the panel you are replacing and try to replicate as best as possible

My dad is a pro welder and reckons that plug welding in some cases is stronger than spot welds .When replacing my seals though he stitch welded it however .

what's stitch welding doug?

Basically i think from what my dad tells me it is were the two panels join a "stitch" line is welded in different parts with gaps in between the welds along the panel joins. Its difficult to explain but the panel sort of look a bit like this:-

- - - - -

The gaps between the dashes being the gaps in the panels. Obviously to make the rust proof you can use seam sealer to fill these gaps.

I know what you mean...

it was done to the sills I took off my Mini.... they fell off!! either C**p welding or worse....

Yer lol

Most probably craply done as lots of people cheat by only doing one side of the panel were for the most effective way you should if possible do a zig zag pattern if you see what I mean

so it would look something like this either side of the panel

- - - - - - weld
------------ panel
- - - - - -weld

Also this method is meant to be stronger than spot etc . My dad sometimes uses this method when welding plates etc to major rsj's and in 18 years has never ever had a complaint.

Wouldn’t bother with a spot welder, would be easer to drill a hole and weld thru.

Then I got to grind the welds flat :doze:

[steveobennet]

certianly have got the motivation at the mo have ye? i can see the convience of spot welding, but if you already have a mig welder why not plug!

[Dog]

Its got to be done...
I've asked for a magic pixie to come and do it, but no one turned up

So I've knuckled down, and I just to get it done! I'd prefure to spot weld the sills, as its just going to look a whole lot neater!

Ain't that seam-welding?

The same was done to our Mk3 Fiesta shell at college before we welded in the rollcage.

Its hard to explain mate. I will explain if you come down or whatever if you ever need welding done and dont want to do it yourself
