| 11. | The traditional techniques of forge work including riveting, banding and forge welding continue to be practised.
|
| 12. | Forge welding grew from a trial-and-error method, becoming more refined over the centuries.
|
| 13. | Blacksmithing : metallurgy, traditional methods, modern methods, forge welding, knives, weapons, armor.
|
| 14. | The Middle Ages brought advances in forge welding, in which blacksmiths pounded heated metal repeatedly until bonding occurred.
|
| 15. | Forge welding between dissimilar materials is caused by the formation of a lower melting temperature eutectic between the materials.
|
| 16. | Forge welding can be used for a much wider range of harder metals and alloys, like steel and titanium.
|
| 17. | In forge welding, the pieces to join are heated to what is generally referred to as " welding heat ".
|
| 18. | Sometimes the final product is all steel, sometimes techniques like case-hardening or forge welding were used to make cutting edges stronger.
|
| 19. | This generally makes forge welding more versatile than cold-diffusion techniques, which are usually performed on soft metals like copper or aluminum.
|
| 20. | Roll welding is another forge welding process, where the heated metals are overlapped and passed through rollers at high pressures to create the weld.
