Titanium Beta Transus Control

When welding titanium, you have to keep an eye on the beta transus – that's the temperature at which the structure changes from alpha to beta phase. If you cool too fast, the material becomes hard and brittle; if you cool too slowly, you lose strength. The trick is to control the cooling to get a clean, homogeneous structure. Make sure the heat-affected zone doesn't overheat and the weld cools evenly, then the part will withstand the load.
