Identification Description
weldabe without limits — welding is done without pre-heating and final heat treatment
limitedly weldable — welding is possible at heating to 100−120°С and further heat treatment
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 alloy gost SP17 is not inferior to steel By strength, but it is twice lighter and differs with heat resistance, 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 as a structural material are of the utmost interest in spacecraft engineering.


Alloying increases strength characteristics and corrosion resistance of titanium 2−3 times as much. One of the main alloying elements is aluminium. It is present in almost all types of titanium alloys. Vanadium, molybdenum are the most important alloying components after aluminium. High-resisting titanium alloys are based on a ternary system — titanium-aluminium-molybdenum. Extra-high tensile titanium alloys are based on titanium-aluminium-vanadium. Due to well-established trend of multicomponent alloying, most of modern titanium alloys at the same time contain aluminium, vanadium, molybdenum in their composition.
