Aluminium titanium nickel copper and magnesium alloys.
Tungsten welding rod chart.
Suitable for dc and ac welding.
Although thoriated electrodes tend to be the favorite for a one size fits most welding approach some electrodes are better for particular metal combinations.
Iso w lanthanated 1 5 ewla 1 5 general purpose electrode used for steel and stainless steel at a wide range of currents.
By qualitytech july 13 2016.
Pure tungsten ewp used primarily for ac welding of aluminum and magnesium at low currents.
And for microplasma welding.
Additionally many welders have their own preferences that fit their unique situations.
Can be used for unalloyed and high alloy steels.

The electrode is made up of materials which are similar to that of the metals chosen to be welded.
All four welding rods have their own qualities strengths and weaknesses.
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.
Often used as a cheaper safer substitute for high priced thoriated.
Tungsten electrodes for ac welding of aluminium alloys.
Tungsten inert gas tig welding.
Increased ignitability thanks to lanthanum oxide.
Many of our customers are often looking for a good reference for which electrode type to choose while welding different metals.
Only limited suitability for dc welding.
Choose the wrong one and your welds will.
