Titanium’s very high affinity for oxygen is also its greatest disadvantage in welding.
Above the liquidus line, titanium increasingly forms a bond with oxygen. As a result, defects form in the lattice structure when the material solidifies. This is shown by the formation of cracks.
For titanium welding, this means that extreme care must be taken to ensure that no oxygen is present in the welding atmosphere.
In addition, the graduation of the titanium must be taken into account in order to select the correct filler metal.
