Only limited suitability for dc welding.
Aluminium titanium nickel copper and magnesium alloys.
The tip of the tungsten must be balled before using.
Many of our customers are often looking for a good reference for which electrode type to choose while welding different metals.
Tungsten inert gas tig welding.
Can be used for unalloyed and high alloy steels.
Additionally many welders have their own preferences that fit their unique situations.
Pure tungsten ewp used primarily for ac welding of aluminum and magnesium at low currents.

Below you ll find a small welding rod chart comparing all the different aspects of these electrodes and a few other common types which you can use as a quick reference guide to help you out in the workshop.
Suitable for dc and ac welding.
Often used as a cheaper safer substitute for high priced thoriated.
And for microplasma welding.
Iso w lanthanated 1 5 ewla 1 5 general purpose electrode used for steel and stainless steel at a wide range of currents.
An electrode or a welding rod is a wire which is made up of wire and is coated.
All four welding rods have their own qualities strengths and weaknesses.
Although thoriated electrodes tend to be the favorite for a one size fits most welding approach some electrodes are better for particular metal combinations.
