Welding filler

(1/1)

Larry Gocha:
 I see something about using Brutus filler rod on 4130 I've never heard of it anyone know what it is.

dreracecar:
I have also heard of the term "Missile Rod"

Its a Stainless type filler rod, that welds pretty fast and works around impuritys in the base metal.
Off road guys like it because its a real pretty weld, but they are dealing with .095 and .120 wall tubing and not .049 and .058
Will not make any difference on how the car works or lasts

Larry Gocha:
Hey Bruce do you still have dzus springs for sale?

dreracecar:
Yes

Rusty Kramer:
I am not and expert but this is what I have found out in my years of asking builders and people in the welding training industry.
 ER70S2  or  ER80SD2  best for Tig welding 4130.
