WebApr 8, 2005 · Pure argon tends to have a colder arc so I'd say use the mixed gas (75% argon/25% CO2 or something similar). If you are worried about the strength, you can "normalize" the weld by heating it to a light cherry color after welding & allowing it to cool slowly. That will make it less prone to cracking. Apr 7, 2005. #6. WebJan 8, 2009 · 4130 steel-an alloy steel, is commonly referred to as chromoly, an alloy which contains chromium and molybdenum among other elements. The number ‘4130′ is a code that the American Iron & Steel Institute (AISI 4-digit code system) uses to define the approximate chemical composition of the steel.

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 … WebSep 8, 2010 · That said, T-1 wires do have disadvantages that limit the chrome-moly applications on which they can be used. First, T-1 flux-cored wires tend to create welds with slightly higher oxygen content than other filler metals, typically 600 to 1,200 parts per million (PPM). Compared to stick electrodes or T-5 flux-cored wires (to be discussed later ... birchwood sl

WebJan 16, 2009 · ER80S-D2 is a higher strength steel filler that contains 1/2% of Molybdenum and more closely matches the strength of the 4130 than the ER70. You … WebJan 28, 2024 · 4130 chromoly is a chromoly welding filler that melts when exposed to heat. It forms a puddle that fills holes and holes between the welded area and surrounding metal surfaces without the need for weld deburing. It cannot, however, be welded with welding rod. It’s also stronger than 4130 chromoly, but it’s rarely used in welding … In many motorsports and aerospace applications, engineers want some degree of ductility in the weld to help absorb impacts and prevent cracking. For this reason, most NHRA fabricators intentionally dilute the strength of the parent material by selecting ER70S-2 for filler for roll cages, chassis and other … See more Fig. 2 summarizes the welding procedures, consumables and variables required for most tubing applications.
