While you probably know that welding refers to the process of using heat, pressure, or fillers to join two or more materials, you might not know that there are several different types of welding processes. Each one has its own applications, advantages, and disadvantages.
There are two main types of welding: fusion welding and solid-state welding.
When materials are melted down in order to be joined together, that’s fusion welding. Any welding process that doesn’t involve melting is solid-state welding.
Heat is often still part of the process in solid-state welding. For example, it can be necessary to apply heat to get a solid joint, a reason that solid-state welding is sometimes called pressure welding. However, temperatures don’t reach the melting points of the materials being joined.
Solid-state welding makes it easier to join different types of metals. Also, because it doesn’t involve melting points, there’s less worry about distortion resulting, and the weld has a more elegant appearance. In addition, the heat-affected zone (HAZ) is smaller.
Solid-state welding requires a special edge preparation, joint design, or surface finish. Since some solid-state welding processes do not use filler metals during the welding process, these processes may not be able to fill a wide root gap, which is the minimum distance between the ends of the elements to be welded.
Several different types of solid-state welding exist.
When your business calls for one of the solid-state welding processes, where can you go? Do you know which welding type is best for the job?
Finding the right answers to those questions takes time, time that you can’t afford to lose since it can cost both productivity and money.
