|limitedly weldable||welding is possible at heating to 100−120°С and last heat treating;|
|hardly weldable||in order to obtain a qualitative welded joints, it is necessary to perform the following operations: while welding to heat it up to 200−300°C, to do a heat treating (annealing) after welding;|
Titanium and its alloys are not inferior to steel by strength, but they are twice lighter. They differ with heat resistance and low heat conduction. Advantages of titanium are very promising in technical fields that require high strength-to-density ratio, heat resistance in combination with high corrosion resistance. Food, chemical industries, aviation, rocket-building, shipbuilding, motor vehicle mechanical engineering cannot do without titanium. Extraordinary characteristics of this metal in the capacity of a structural material are of the utmost interest in spacecraft engineering.
