What is welding?
Forge welding is an old technique that involves joining pieces of metal by heat and strength. The metal is generally heated by fire and the force is usually applied by a hammer, but there are other methods. Forge welding is considered to be the basic technique. It is still taught and used, but is commonly replaced by more modern welding techniques. Some methods are complex and may require good concentration, memory and security skills. It is also beneficial to know the characteristics of the metal that is welded and the heat source used. This is because thin pieces can bend around when heated, resulting in pockets that appear as bubbles on the surface. Stronger pieces of metal also tend to maintain heat longer. The pieces that are selected should usually be usually without oxides and contaminants before starting welding.
The flow is generally applied after the metal heated, but before reaching its welding heat. Flux is a substance that melts and creates a coating that prevents oxidation. Borax is a runIt may not be suitable for all materials. If the metal oxidizes, the result is generally a low -quality forge.
The pressure source varies depending on the welder's preference and technique. Some use hand hammers while others use Power Hammers. Others can use printing. Regardless of which pressure tool is used, Forge often burns.
In many cases, knowledge and experience are the only way to find out when the metal is hot enough to be created. This is also important to prevent metals too hot. Various metal welding at different temperatures. It is estimated that these temperatures are between 50 and 90 percent of the metal melting temperature.
This process works, so the metal is heated to some extent, changes in the molecules. When the pressure is exerted, the elements from one piece of metal can cross the other piece. The result of this exchange is a bond. Forge weldingcan be done with similar or different metals. When different metals are used, the welded product is generally stronger than one of the metals individually.
When the process is successful, there would be no cracks or gaps between the layers. This is true, even if several layers are welded together. Forged materials should seem like one fixed item.
