not limited — welding is carried out without further heat treatment and without heating
weldability with limitations — welding is possible when heated to a temperature of 100−120°C and further heat treatment
hard-welded — to obtain a quality weld, additional operations: during welding -preheating to a temperature of 200−300°C, heat treatment after welding — annealing


As to its strength titanium and its alloys are not inferior to steel but lighter by almost half, are heat resistance, low thermal conductivity. Advantages of titanium is very promising in technical fields that require high specific strength, heat resistance, combined with high corrosion resistance. Food and chemical industry, aviation, shipbuilding, aerospace, vehicle construction today can not do without titanium. Unusual characteristics of this metal present a great interest as a structural material in spacecraft.


Alloying increases the corrosion resistance of titanium and its strength properties 2−3 times. One of the main alloying elements are aluminium, present in almost all alloys of titanium. The most important alloying components, followed by aluminum are vanadium, molybdenum. High-temperature titanium alloys based on the ternary system — titanium-aluminum-molybdenum, high-strength titanium alloys of the system titanium-aluminum-vanadium. Most modern titanium alloys due to well-established trends multicomponent alloying at the same time in their composition contain aluminium, vanadium, molybdenum.
