Welding is a very hot process. When you weld, you are heating up metal and causing it to melt. The temperature of the metal can vary depending on the type of welding. For example, oxy-acetylene welding will be hotter than gas tungsten arc welding
This article explains why metals have to be heated up so high and what affects their melting point so much.
how hot does metal have to be to forgeMetal forging is a manufacturing process in which metal is heated and placed under pressure to produce parts with a desired shape. Forging can be done using a variety of tools and machines, such as hammers and presses, to shape the metal into the desired shape. The process of forging can produce parts that are stronger and more durable than those made using other manufacturing methods. Many different metals, including steel, aluminum, and brass, can be forged using this process.
Once we open the die/mold of forging process and get ready, then we start forging mass production.
The processes of forging are as below:
1/ The metal is heated to a high temperature in a forge or furnace. The heated metal is placed on an anvil or forging die.
2/ The metal is struck with a hammer or press to shape it into the desired form.
3/ The metal may be reheated and reshaped multiple times to achieve the desired shape and properties.
4/ The metal is cooled and hardened by quenching it in water or oil.
The forged metal parts normally need further processed by machining, heat treatment, or other methods to achieve the final desired properties and finish.
