Meet Your ArcAngel...
EWI DeepTIG™ gives you welds that are up to
300% deeper, more consistent, and higher quality.
Simply miraculous.
EWI's patented compounds for gas tungsten arc welding help increase weld penetration by as much as three times. These unique metallic oxide compounds are available in a powder form. The powder is combined with a liquid carrier to form a slurry that is then applied to the top face of the joint to be welded.
The metallic oxides change the weld metal flow such that penetration is increased while the quality of the weld is improved. These compounds have been developed through extensive research carried out by EWI and the Navy Joining Center (NJC). Repeated testing has proven that the mechanical properties, weldability, and corrosion resistance are not affected in most of the cases.
Benefits
The benefits of EWI DeepTIG include:
- Increases weld penetration by as much as 3 times
- Improves consistency of welds
- Improves quality of welds and reduces reject rates
- Reduces distortion
