Ford block production line weld repair .....

Post by BCjohnny »

I once had a (since lost) reference of Ni rod repairs to as cast Ford V8 block 'blemishes' as they rolled down the production line, often in the valley

Anyone post up, or can point me in the direction of such ?

TIA John

I've seen it on old SBC head rocker cover rails.

Thanks Tom68, I'd guessed it was commonplace* ......

I've a particular casting with such a repair in the valley, without such provenance it's just a 'weld' ....... motive being purely the filthy lucre, although I have a more general interest in manufacturing procedures

[* I've a couple of machines with nickel rod repairs to correct mis-runs in a major casting, Zanrosso surfacer table for example]

I've always assumed they've done them hot, stick welded from what I've seen. I've Tig welded mild steel flanges to cast turbo housings using Nickel arc electrodes with the flux chipped off, no pre heat no problems. Cast just depends on the properties, some weld easily others don't weld at all.

Yes, the only process I've seen used ...... still hot from the shake out, there'd be the usual suspect areas to check

Not the best pics, but it'll give an idea about what I'm referencing

There is no 'damage' surrounding, or any other evidence to suggest that it's a post machining repair

Wow, that's pretty serious, looks like they've used a nickel alloyed electrode, the Chev head repairs I've see have a shinier weld deposit.

Weld looks 'duller' than it actually is, as though it was shot blasted along with the bare casting, post shake out and prior to machining

But I wouldn't doubt that Ford might 'economise' with the electrodes to save some pennies, using an alloy rather than pure Ni, if it did the job

It doesn't appear as deep as it looks, doesn't go into water or the gallery, so is mostly a 'blemish' repair IMO

I'm sure the Chevy ones are a Nickel alloyed rod to.
