WebIn either instance, both filler rods offer overmatching strength (more than the 70,000 psi of the 4130 chrome-moly tubing itself). S-2 fillers clean impurities better than D-2 fillers Should I go for the stronger ER80S-D2 rod OR for more flexibility, ductility and cleaning properties of the ER70S-2 given it will be for an engine mount? WebMar 1, 2008 · Filler-ER70s-2 or -6 Tungesten-old standard is 2% thoriated....others will work though Argon flow and Cup size depend on your joint configuration. Cleaning-Clean ALLLLLLL oils from the base material and filler, use a non heavy hydrocarbon solvent of choice and be sure its all evaporated before welding.
Best welding rod (tig) for welding 4130 chromoly tubing
WebA common filler metal choice for welding chrome-moly is ER80S-D2 .This filler metal is capable of producing welds that approximate the strength of the 4130. ER70S-2 is also … WebMIG Wires and TIG Rods Filler metals made from the highest quality steel to maximize consistency, feedability and arc performance. ... Can I weld 4130 using any other filler metals? A. Some fabricators prefer to use austenitic stainless steel fillers to weld 4130 tubing.

MIG Wires and TIG Rods Filler metals made from the highest quality steel to maximize consistency, feedability and arc performance. WebI would use E70S-2 mild steel tig welding rods. and btw, I would use this for all your chromoly welds. the oxweld does not have any good stuff like silicon to scavenge the junk. i bet it spits sometimes. with E70S-2, the welds will be a tiny bit stronger than the mild steel but not quite as strong as the chromoly. This is normal. WebMay 1, 1994 · Additional metal is added for strength in the form of filler rod. ... When speaking about aircraft welding, it is important we take into account the material characteristics of chromoly because the very factors which give it its high strength-to-weight ratio, including its carbon content, are also what make it more critical to weld than lower ... how are genotypes and phenotypes similar
