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


With doping increase the strength characteristics and the corrosion resistance of titanium in 2−3 times. One of the main alloying elements in industrial titanium alloys is aluminum. The most important alloying components, followed by aluminum are vanadium, molybdenum. High-temperature alloys based on the ternary system — titanium-aluminium-molybdenum and titanium-based alloys — titanium-aluminium-vanadium. Most modern titanium alloys due to well-established trends multicomponent alloying at the same time in their composition contain aluminium, vanadium, molybdenum.


Titanium and its alloys are strong, paramagnetic, quite easily welded and has some properties that play a number of technical industries an important role. Advantages of titanium alloys have great prospects of applications in such industries as engineering, which require high specific strength, heat resistance combined with high corrosion resistance. It is also important in such industries as food, chemical, aviation, shipbuilding, aerospace, high-speed transport. Extraordinary characteristics of titanium present great interest as a structural material in spacecraft.
