Welding Rod Tungsten. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas. With low burn-off rate and reliable arc-striking these electrodes maintain high-quality arc while adhering to AWS and ANSI standards.
Different types and sizes of electrodes are used for different types of welds and materials and welders develop preferences based on welding style and project. If your electrode isnt set up correctly you cant get a clean strong weld. Because they deliver nice stable arc these premium quality 2 Lanthanated Tungsten Electrodes are ideal for TIG welding aluminum stainless and mild steels and other special metals.
The most commonly used electrodes today are 2 Thoriated red stripe.
Tungsten has the highest melting point of any metal 3410 degrees Celsius. The external filler metal is often a filler rod but the materials can vary. Its good current carrying capacity low spark erosion and no radioactive hazard help maintain its irreplaceable position in DC and AC welding applications. However larger rods require more heat and excess heat promotes burn-through warping and embrittlement.
