GENERAL WELDING INFORMATION. Purchase only electrodes that are in hermetically sealed containers. Store the rods in those containers. Open containers should be stored at 250°F to 300°F. Typical re-drying temperatures are 650°F to 700°F for one hour. (Longer at
Feb 20, 2009 · #2. Actually in most cases you do not want to use 4130 welding rod when you are welding on 4130 base mat. Normally you would use either ER70s-2 Or what you mentioned ER80s-d2. The 70 and 80 stands for the tensile strength in thousands. Both are a mild steel rod but work well on 4130.
Sep 20, 2009 · Depending on what you are making you can get yourself in real deep. Modern Welding by Althouse/Turnquist/Bowditch and Lincoln's book - The Procedure Handbook of Arc Welding are good for start. The FFA also has a lot of info or procedures for welding
Nov 11, 2013 · In this case, the number is 4130. American standards covering pipe materials are ASTM, ASME Section II, API, AWWA. If there's another one, I don't know. ASME Section VIII covers pressure vessels, not pipe. ASME Section IX rules the approval of welding procedures and welders. Pipe materials are also covered by ISO standards,, buy api 5l x65 specification
Welding 4140 to stainless. Since hastelloy W has become so expensive, 309 stainless filler was used to weld the 4130 to 303. welding free machining 303 stainless is not even recommended for some applications but this particular part was more like an alignment gauge and
Our shop won a contract that requires welding 4130 steel. I've been told this is a heat-treatable steel. Can you tell me which different welding procedures have to be used to weld this material? The most commonly welded heat-treatable steels are 4130, 4340, and 8630. However, any steel prefaced with a 41, 43, or 86 is considered heat-treatable.Some results are removed in response to a notice of local law requirement. For more information, please see here.
What consumable can be used to weld on SAE 4130 steel tubing? On light chrome-moly tubing, mild steel electrodes are commonly used. There is enough pickup of alloy from the base material to give the required tensile strength in the as-welded condition. On multiple pass welds, Cro-Mo alloy electrodes are usually specified.Some results are removed in response to a notice of local law requirement. For more information, please see here.
4130 is a Chromium-molybdenum low alloy wire that will produce a dense, heat-treatable deposit. This alloy is used to weld AISI/SAE 4130 and 8630 and other heat-treatable alloys or base metals needing flame hardening.Preheat and inter-pass recommended and may also need followed by post heat treating.

Best Practices for TIG Welding of 4130 Chrome-Moly Tubing In General Motorsports and Aerospace Applications. The 4130 grade of chrome-moly is a high-strength low-alloy (HSLA) steel that contains molybdenum (0.15 - 0.25 percent by weight) and chromium (0.8 -
This article provides some best practices for selecting the proper filler metal for welding 4130 heat-treatable low-alloy steel, along with recommendations for pre- and post-weld heating. Because of its high hardenability, 4130 steel responds well to heat treating, which offers advantages for many applications.
Tips for welding 4130 and 4140 steel Many of the challenges and best practices for welding 4130 and 4140 steels are the same whether the application involves welding new material or making repairs. Consider these six important steps when welding or repairing 4130 and 4140: Identify thermal treatment.
The Procedure Handbook for Arc Welding suggests using a preheat of 400-500F for thickness up to 1/2 inch and 600-700F for thickness of 1/2 inch to 2 inches. If this weld requires multiple passes make sure your interpass temperature is the same (minimum) as your preheat.
One of the main reasons the 4130 is mainly tig welded and most experts agree, the transfer of a mig weld to 4130 is more harsh and quicker than a tig weld. The "short arc" transfer with 4130 creates a possibility of more embritlement along the weld.See more results
A TIG finger Heatshield is great for welding 4130 chromoly tubing, buy api 5l x65 specificationClick on the Image below to learn more. Compare it to 1010 steel as far as how hard it is to bend and there really is no comparison. Just get a piece of 1/2 inch tubing and try it. You will strain your left testicle trying to bend chromoly tubing. There are other chromium molybdenum steels like 4140 and 4340 but one of the most common chromoly
Here are answers to the top ten most frequently asked questions about TIG welding 4130 Chrome-Moly. These attached procedures apply to typical sporting applications such as experimental airplanes, racing car frames, roll cages, go-carts, bicycles, and motorcycle frames.
A 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 an acceptable alternative to ER80S-D2, as well as 70S-6, although weld strength will be slightly lower.
When welding 303 to itself, I have found 308L to be the best choice, but for welding 4140 to 303 stainless, 309 stainless, 312 stainless, or hastelloy W are all good choices. Since hastelloy W has become so expensive, 309 stainless filler was used to weld the 4130 to 303.
