Welding rods

[Remlap]

Sorry for my ignorance but could someone enlighten me on what these rod numbers mean ie 6013 etc, and what situation each is best suited for?

Miller has a description of AWS types here.

the first two numbers is the tensile strength of the Rod

The 3rd digit tells you what position the rod is recommended for.
1 : Flat, Horizontal, Vertical, Overhead.
2 : Flat and Horizontal only.
3 : Flat, Horizontal, Vertical Down, Overhead

The last digit tells you about welding current and the coating
1 : DC:ROD+ ................... cellulose sodium
2 : AC or DC:ROD+ or DC:ROD- .. cellulose potassium
3 : AC or DC:ROD- ............. titania sodium
4 : AC or DC:ROD- or DC:ROD+ .. iron powder titania
5 : DC:ROD+ ................... low hydrogen sodium
6 : AC or DC:ROD+ ............. low hydrogen potassium
7 : AC or DC:ROD+ or DC:ROD- .. iron powder iron oxide
8 : AC or DC:ROD+ ............. iron powder low hydrogen

it is usually written on the box which polarity to use and what amps you need to use and also what the rods are best suited for

Ah, cheers Scarecrow.

I didn't know that there actually was some logic behind the AWS codes. Live and learn eh

maybe this will help what your looking for is the iso classifications otherwise the difference is the first two no. our tensile strength is in MPa. hope this helps i cannot stress enough the importance of choosing the right stick for the job. know the parent metal and then choose a rod for the application. 2.5mm rods are better for smaller machines, using smaller rods for larger and crucial welds is not advised or easy, but not impossible. get peno and then place welds carefully and and so on, make sure you thoughly remove all slag

There is some logic, but it is not complete.

There are a lot of suffixes for variances in the rods. -AC for use on low OCV AC buzz boxes (usually used on 7018). There are other suffixes for things like low-temp, flux options, and some filler metal additives.

The ISO codes are probably more complete, but are much more complicated to read

http://www.welding.com.au/products.asp, try this link it is aussie but it does have AWS and ISO numbers and a description of uses. hope it helps, was unable to upload it, last time,
