DID YOU KNOW?
In the United States and Europe, friction welding has been in used for more than five decades. Today, the friction welding process may be renowned, but for a long time, this process was a well-preserved secret in the manufacturing industry.
FRICTION WELDING – A PERFECT TECHNIQUE TO SEAM DISSIMILAR METALS
Friction Welding as defined by Wikipedia – “Friction welding (FRW) is a solid-state welding process that generates heat through mechanical friction between workpieces in relative motion to one another, with the addition of a lateral force called “upset” to plastically displace and fuse the materials. Because no melting occurs, friction welding is not a fusion welding process in the traditional sense, but more of a forge welding technique. Friction welding is used with metals and thermoplastics in a wide variety of aviation and automotive applications..”
During the process of friction welding, a part is rotated due to which it is sometimes known as a spin weld or spin welding process.
The friction welding process’ capability to build near-net shape blanks provides manufacturers with a chance to diminish material consumption and reduce welding cycle production duration. With the help of the friction weldingmethod, a wide variety of dissimilar metals can be joined in their full-strength weld, without giving up on the weldreliability or strength. This joining of different metals together provides unique design flexibility.
In order to satisfy more complex joining needs, a solid-state process – Rotary Friction Welding can be divided into two kinds of friction welding technologies:
1. Direct drive rotary friction welding
2. Inertia friction welding
The direct drive friction welding method is controlled by computer. Inertia friction welding method also uses a process that includes part rotation under pressure to heat the fraying surfaces. What sets both the methods apart is that the inertia method involves the usage of a flywheel to generate the rotational momentum in the part-holding chuck.
ADVANTAGES OF THE FRICTION WELDING METHOD
For years, the friction welding process has been upheld as more flexible and cost-effective compared to other conventional welding techniques. Let’s decipher the advantages of friction welding in detail:+
- Friction welding facilitates joining of dissimilar materials, which further leads to decrease in material costs. Metal groupings that are commonly considered to be incompatible can be easily joined by friction welding.
- It is a complete machine controlled welding method. The machine makes spin welding a consistent and repetitive procedure and reduces any kind of human error while the production is in action.
- Spin welding narrows down the heat-affected zone and gives more efficient joints and much stronger welds.
- It curtails the requirement of cleaning the furnace residue after the completion of the welding process.
- The welds joined through this process have superior strength bonds and versatility in design.
- Spin weld is an environmentally-friendly welding method – no consumables, fumes or gases are produced. To add, there is even no weld splatter generated.
