	Forge welding - Wikipedia, the free encyclopedia
		Forge welding is a welding process of heating two or more pieces metal and then hammering them together.
		Forge welding between similar materials is caused by solid-state diffusion.
		Forge welding between dissimilar materials is caused by the formation of a lower melting temperature eutectic between the materials.

	Welding - MSN Encarta
		Welding processes are generally classified according to the sources of heat and pressure used.
		The surfaces to be welded and the welding rod are coated with flux, a fusible material that shields the material from air, which would result in a defective weld.
		In shielded metal-arc welding, a metallic electrode, which conducts electricity, is coated with flux and connected to a source of electric current.

	Hand Forging and Welding-Soldering, Brazing, and Thermit Welding
		Welding with the heat of a flsmith forge fire, or a coal or illuminating gas fire, can only be performed with iron and steel because of the low heat which is not localized as with the oxy-acetylene and electric processes.
		With the work at welding heat, the two parts are driven together by hammering on the rear ends and the hammering then continues as with a lap weld, except that the work is turned over to complete both sides of the joint.
		Other forms of welds in which the parts are too small to retain their heat, can be made by first riveting them together or cutting them so that they can be temporarily fastened in any convenient way when first placed in the fire.

	Types of Welding Processes
		Forge welding Forge welding, the oldest known form of welding, is a welding process of heating two or more pieces of wrought iron or steel until their surfaces are malleable and then hammering them together.
		Fusion welding Fusion welding is any welding process that uses a heat source to weld a material and also usually uses a protective shield from the atmosphere by a gas shield or flux or both.
		Gas welding In gas welding, the heat energy and high temperature needed to melt the metal is obtained by the combustion of a fuel gas with oxygen.

	Solid State Welding
		Forge welding is a solid state welding process which produces coalescence of metals by heating them in a forge and by applying pressure or blows sufficient to cause permanent deformation at the interface.
		Welding this metal to the clean metal of the abutting part is accomplished by diffusion across the interface so that coalescence of the faying surface occurs.
		Welding occurs when the ultrasonic tip or electrode, the energy coupling device, is clamped against the work pieces and is made to oscillate in a plane parallel to the weld interface.

	Forge Welding
		It is possible to weld at a dull red heat, what is required for a good weld is that the metal be clean of oxides and contaminants and that the surfaces be mated.
		After the weld was made, I would stand the billet on its edge and draw it out flattening it on the edge of the weld.
		If you are welding with a hand hammer, run a series of light blows from the far end to the handle end directly up the middle of the billet and then with quick light blows go around the outside edges of the billet.

	Forge Welding Part II : anvilfire iForge Demo
		A forge weld is generally stronger than a torch weld.
		Forge welds that that are not mostly completed in the first heat are hard to redo.
		In thinking about a lap weld, in the early shops, there was almost always one or more helpers, and the helper held the one piece which belonged on the other side of the anvil.

	Forge Welding
		In a well designed forge it reaches easily temperatures of 2200 degrees at 4 psi and it is capable of reaching temperatures high enough to melt graphite.
		Then you take it out of the forge and either start gently pounding on it with a hammer so that you hit evenly the entire surface or you take it to a press and let the press do the job for you.
		Most weld failures are due to either not reaching high enough temperature for the weld to take or impurities in the surfaces to be welded.

	Welding - Wikipedia, the free encyclopedia
		Welding, however, was transformed during the 19th century—in 1800, Sir Humphry Davy discovered the electric arc, and advances in arc welding continued with the inventions of metal electrodes by a Russian, Nikolai Slavyanov, and an American, C.L. Coffin in the late 1800s, even as carbon arc welding, which used a carbon electrode, gained popularity.
		Shielded metal arc welding was developed during the 1950s, using a consumable electrode and a carbon dioxide atmosphere as a shielding gas, and it quickly became the most popular metal arc welding process.
		Welding in space is also possible—it was first attempted in 1969 by Russian cosmonauts, when they performed experiments to test shielded metal arc welding, plasma arc welding, and electron beam welding in a depressurized environment.

		Forge welding is done by taking two pieces of steel to the correct temperature and pressing the two pieces together via hammer blows.
		Quickly use your tongs to take your cable from the forge to the anvil, you only have a little bit of time to work at a welding heat ("strike while the iron is hot" means exactly that to the would be smith).
		Once your weld reaches the center of the cable turn it around, but keep the weld working down the cable in the same direction (so that you finish at the opposite end of the cable from where you started).

	Diffusion Bonding
		forge welding, friction stir welding, explosive welding and solid-sate diffusion bonding.
		Diffusion bonding, as a subdivision of both solid-state welding and liquid-phase welding, is a joining process wherein the principal mechanism is interdiffusion of atoms across the interface.
		Despite the presence of a liquid phase, this process is not a subdivision of brazing or fusion welding as the formation and annihilation of the liquid phase occurs at a constant temperature and below the melting point of the base material.

		I use mostly torches or arc welding, but I still love forge welding (both gas and coal), because I enjoy trying to overcome all the variables that rule.
		Your gas forge needs to get hot enough to make the steel white hot, about 2,500° F. At that temperature the surface of the steel is just at the liquid point.
		Welding in a coal forge is tough, but welding in a gas forge is tougher.

	Welding - Selecting Forge Die Materials
		As the Forgeweld welding consumables have been designed to complement existing forge die materials, the same principles of selection that are applied to die materials can be applied to welding consumables.
		Whether the forging dies are to be used on a drop hammer forge or on a press forge will have a significant influence on the selection of the hardness range required, and therefore on the materials that can be used.
		A high proportion of steels used in forging are weldable, therefore information about base material composition is often more valuable as an insight into the process and potential problems, than purely as a question of weldability.

		However, a properly done torch weld is effectively the same as a forge weld: they both involve melting two pieces of metal and fusing them together.
		Forge welding can be used on larger surfaces (for example, welding a high-carbon plate to the face of a piece of low-carbon stock), as long as you can heat all (or a large section) of each piece to welding heat.

		The arc and weld pool formed using a bare wire electrode was protected by helium gas, readily available at that time.
		MIG is similar to MMA in that heat for welding is produced by forming an arc between a metal electrode and the workpiece; the electrode melts to form the weld bead.
		General purpose shielding gases for MIG welding are mixtures of argon, oxygen and C02, and special gas mixtures may contain helium.

		It is very rare to see layer counts upwards of 400 because at that count the layers would be so thin you would get carbon migration and the steel would basically no longer be layers but instead one new steel created by virtually mixing the steel together into one new steel.

		Many welders today have an interest in the oldest of all welding processes, forge welding, that has been traced back to the Iron Age in Egypt in 1350 B.C. The early forges used by flsmiths were very similar to those still in use.
		Forge welding is a solid state welding process that produces coalescence by the application of pressure without melting any of the joint components.
		A flsmith is then able to create pressure, by the skillful use of a hammer and an anvil, and makes the weld by applying blows sufficient to cause permanent deformation at the faying surfaces.
