Tungsten Welding Rod Chart

All four welding rods have their own qualities strengths and weaknesses.

Tungsten welding rod chart.

Tig welding tungsten electrode selection chart type ac dc recommended usage 2 thoriated red dc copper alloys nickel alloys titanium alloys and non corrosive steels 2 lanthanated blue ac dc aluminum alloys magnesium alloys nickel alloys copper alloys titanium alloys low alloyed steels and non corrosive steels pure tungsten. Additionally many welders have their own preferences that fit their unique situations. 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. An electrode or a welding rod is a wire which is made up of wire and is coated.

The tip of the tungsten must be balled before using. Aluminium titanium nickel copper and magnesium alloys. By qualitytech july 13 2016. Can be used for unalloyed and high alloy steels.

Choose the wrong one and your welds will. Tungsten inert gas tig welding. Increased ignitability thanks to lanthanum oxide. Pure tungsten ewp used primarily for ac welding of aluminum and magnesium at low currents.

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. Only limited suitability for dc welding. Welding rod electrode selection chart.

Iso w lanthanated 1 5 ewla 1 5 general purpose electrode used for steel and stainless steel at a wide range of currents. The electrode is made up of materials which are similar to that of the metals chosen to be welded. And for microplasma welding.
