TWI Frequently asked questions
Friction welding has found worldwide use in varied industries. The main advantages of the process are: -
- Easy automation
- No requirement to use certified welding personnel
- Rapid weld times
- Reproducible quality
- Autogenous - no filler metal
- Absence of porosity and solidification cracking
- Environmentally friendly
Mass production industries such as automotive, electrical, and domestic appliances have adopted friction welding for the above reasons. Alternatively lower volume production industries such as aerospace, chemical and nuclear havebenefited from the high weld integrity and the ability to join dissimilar metal combinations.
