Best Way, I have found is a low hydrogen electrode or wire, preheat to 3-400C make sure to bevel so weld only is attaching to one material per pass, small stringers, keep the heat as welding, post heat back to 3-400C, let cool by propane space heater. (Excavator buckets etc..? Yeah- we can do that at Rods M Shop.

What Welding electrode can be used to weld A 36steel to AISI 4140 steel?
I have experience when my team welded "JIG Ladle" A36 to AISI 4140, we used electrode E7018 with SMAW process. The important thing for this welding's prehating during welding min. 180 degree celcius and did peening the weld beads to minimize residual stresses. After welding covered by blanket for slow cooling. Regards, Asep S (asep93st@yahoo.com)

How is steel wire mesh welded?
Steel wire mesh is welded by spot welding which could be continuous or staggered, depending on the application and strength of joints required. Sometimes, they are fastened by screws to the frame which serves as retainer also.
What is 4140 mild steel?
I think you're looking at two separate terms. SAE 4140 steel is a Chromium-Molybdenum steel used extensively for axles, aerospace concerns, and firearm manufacture. Mild steel is a catch-all term for plain carbon steel of low carbon content (such as SAE 1018) which is generally cheap, not heat-treatable, and used for fairly low-strain applications. I hope that helps. Mike Source - Machinery's Handbook, 11th Edition, 1943
What temperature does mild steel turn red?
pls refer to carbon-phase diagram... mild steel will be liquid and welded with temp. of >1300degC
What is 4140 stainless steel?
It's a misnomer. 4140 is a type of steel, which is NOT stainless.
What is the equivalent material for 4140 grade steel?
EH 36
What is the density of 4140 grade steel?
0.282-0.283 lb/in3
Can hot dipped galvanized steel be welded?
Hot dipped galvanized steel can be welded and is available as HOT DIP GALVANIZED WELDED WIRE MESH. Galvanizing is a process where zinc is applied to steel to protect against corrosion. It is also used to give steel a bright finish.
How are steel wheels made?
On a steel press then spot welded together

What metals can be welded by underwater welding?
steel
What materials is a army tank made from?
Prior to 1941 they were built from riveted steel. From 1941 thru 1945 they were cast steel and welded steel. From the Korean War thru Vietnam they were cast (with some welding) steel. With the one exception of the Vietnam era M551 Sheridan tank which was welded ALUMINUM (hull only). The Sheridan's turret was welded steel (and the gun was steel). Post Viet War US tanks are composite (classified) armor with steel exteriors (welded).
Can steel be folded?
Yes, steel can be folded. This is a common practice in the production of "damascus" or pattern welded steel.
How do you weld 4140 steel?
Preparation: Ensure the 4140 steel workpiece is clean and free of any contaminants, rust, or scale. Place the workpiece in a heat-resistant container or fixture that allows for uniform heating and cooling. Heating: Preheat the furnace or kiln to the annealing temperature, which is typically around 1600°F (871°C) for 4140 steel. Insert the workpiece into the preheated furnace. Make sure it is supported and positioned to ensure even heating. Allow the steel to soak at the annealing temperature for a sufficient amount of time to ensure uniform heating. The soak time may vary but can be in the range of 1 to 2 hours.
Can copper be used in damascus steel?
No as it is unable to be forge welded.
