LONGEVITY FILLER RODS FOR TIG WELDING:

Filler Rods are essential to TIG Welding because the filler rod is fed into the molten puddle by hand filling in the puddle to create a stronger metal bond or puddle to join two metal pieces. It is extremely important to have the right filler rod based on the metal you are Welding. It is also necessary to have the right tungsten to insure you are properly setup to weld your metal. Our Plasma Cutters, Stick Welding Equipments, TIG Welders, MIG Welders and are all insured with our industry leading 5 year parts and labor warranty!*

Longevity offers quality filler rods at affordable prices. Please take a look at the selection of filler rods that we carry to decide what the best application of rod will be for your weld.

Your choice of filler rod is extremely important to the strength and matter density of your weld. You can determine the diameter of the filler rod needed, by the thickness of the material that you will be welding. Here are some pointers in deciding how to choose the correct filler rod for your weld.

  1. 4043 is a general filler rod for most aluminum welding.
  2. 5356 is perfect for 5xxx series aluminum. If you are planning on anodizing the finished piece, this rod should be used for the weld.
  3. ER70S-6 is designed for welding mild steel.
  4. ER70S-2 is recommended for welding 4130 chrome moly tubing in most applications.
  5. ER80S-D2 is for welding 4130 chrome moly tubing if a higher strength weld is required.
  6. 1/16” diameter filler rod should be used when material is 1/8” and less thick. 3/32” diameter filler rod can be used for 1/8” and thicker material.
