Welding on a case-hardened gear? - Metal and Metallurgy welding hardened 8620

Sep 18, 2009 · Obviously mitsubishi case hardened the gear after the welding process, but now i dont have that same luxury. The outer, hardened layer of metal has been machined off at the location of the new weld, and since i would be welding the "core" metal i am wondering what results i can expect as far as strength is concerned.Welding on Hardened 8620 Tool Steel, any suggestions?I may be joining an 8620 pinion gear to an 8620 shaft soon. Both pieces have been hardened, (case hardening) done to them. Does anyone have any suggestions on filler rod/ pre-heat or PWHT temps if necessary for this welding procedure? I have been researching all week, and many suggested 400 F for pre-heat, with slow post weld cooling.Welding Hardened 8620 - Miller Welding Discussion ForumsPerformed in a furnace (gas or electric there's not difference) where the material is in direct contact with the carbonaceous material either solid liquid or gas. essentially it is case hardening and is a bit of a nickname. 8620 is a common material in gears and shafting along with frames and receivers of firearms due to it high strength and it's ability to absorb a shock load to a certain degree

Welding 8620 steel - Practical Machinist

Nov 10, 2014 · At any rate, if you are tigging 8620, "oxweld" or ER 70S-2 would work well for this low carbon steel. The CNC'd "teeth" would help a lot and reduce the heat input requirement due to welding only holding parts "lined up". Maybe you will be lucky and Welding 4140 or 8620 to A36 or A572 Grade 50 plate - Metal welding hardened 8620Lower preheating temperature can be used for the 8620. The weld to the 6" diameter shaft should be post weld heat treated. Successful welds can be made without PWHT using low hydrogen electrodes like E7018 H4. I assume that you will be fillet welding the the shaft to the plate or will the weld be full penetration through the plate thickness?Testing Friction Welding For Strength | American Friction welding hardened 8620Here heat-treat hardened 8620 steel is bonded to stainless steel. The hollow stainless tube was cut for a petal test. The friction weld parameter is proven successful in this test example.

How to Weld Hardened Steel | eHow

Hardened steel is a form of high carbon steel that has been tempered through a heating process to make the metal more durable. Welding hardened steel can be tricky because the heat used in the welding process may cause the metal surrounding the weld joint to become brittle if proper heating and cooling methods are not used to prepare the metal.Encore Metals - 86208620.
