How to weld 1/2"armour plate?

G'day Darrin,

One more tip for you mate make sure you have tin of nozzle dip!!! this dip will help keep the head of the mig welder clean when welding.


cheers for now and good luck

I don't know if it is the same but I had some cracks welded on the scout car. It was a mongrel of a job. A mobile weder bloke did it and after much mucking around successfully welded using rods with a high nickel content - from memory. As Richard mentioned we had to cut a vee in preparation for the weld. I seem to remember heating the rods up in my mum's oven - I don't know if that helped in any way and certainly not for her cooking - but the welds were good.

The TAFE I did welding at, kept the welding rods in a warm oven, it keeps the rods dry . The rods are much better to weld with when they are dry . Any moisture in the rods, it somehow detracts from their performance .

I thought in a country, where your slice of bread curls up and dries out, in the 3 seconds before you try to butter it, that keeping your welding rods dry and warm, wouldn't count........ or is that only in the bad lands out west?

Don't forget, darrin is using a mig and not ark. Heating your welding rods is for preheated cast iron and tempered steel of high stress levels and would not be a issue in this case.
