Filler Rod for TIG Welding
HTP offers you high quality filler rods in affordable quantities.
All filler rod is packaged in 1lb air-tight plastic tubes to keep
your filler rod fresh and contaminant free. The tubes are
completely re-sealable.
In TIG welding, the filler rod is fed into the molten puddle by
hand. The choice of filler rod is extremely important as the
rod must correctly match the material and alloy you will be
welding. The thickness of the material to be welded determines
the diameter of the filler rod.
Here are some good rules of thumb to help you select the
correct filler metal:
1) 4043 is a good general filler metal for most aluminum
applications. Remember 2xxx and 7xxx series aluminum is
generally not recommended if the application requires
welding.
2) 5356 is used for 5xxx series aluminum and is generally
preferred if the finished piece will be anodized.
3) ER70S-6 is generally used for mild steel welding.
4) ER70S-2 is highly recommended for welding 4130
chrome-moly tubing in many applications.
5) ER80S-D2 is recommended for welding 4130 chrome-moly
tubing if a higher strength, less ductile weld is required. If
your weld will be heat treated to obtain optimum strength,
then use a filler metal which matches the chemistry of your
tubing, which neither 70S-2 nor 80S-D2 wires do.
6) Generally speaking, use a 1/16" diameter filler rod for
applications where the material is 1/8" and less. Use a 3/32"
diameter rod for 1/8" and thicker.
The following Filler Rod is available from HTP in 1 lb. tubes
which are tightly sealed to prevent oxidation.
