Wire produced in degassed, etched condition. Ovality welding titanium wire can not be greater than its diameter for maximum deviations. The surface of wire should be clean, bright, without reproterol, dark spots, tint. Allowed on its surface, minor tears, with dark pprotray. The surface of the welding wire may have small tears, small risks, sunsets with a depth not exceeding the dimensions given in the table.
|Diameter titanium wire Vt6sv||The depth of the defect in the wire brand Vt6sv shall be not more|
Note. Valid on the surface of the wire in the presence of small individual defects in the wire diameter up to 3.0 mm deep, exceeding the limit of 0.1 mm, and the diameter over 3.0 mm — 0.2 mm.
The correction of impurities, surface defects by means of etching, Stripping to degassing of the wire. Allowed in the future, Stripping only a small unit of pollution. It also allowed the etching separate bays with subsequent degassing repeated. The total marked macrosections exceeding the depth of the defects in the metallographic process control can not be higher than 10% of the total macrosections of a controlled party.
Titanium wire winded into a coil. Its outer diameter is 900 mm. the Coils of wire in the Bay should not adhere to each other and have curves of more than 100°. Waviness titanium wire, which occurs upon annealing of the coils, is not a sign of marriage. Mass Bay together with wire cannot be more than 50 kg. In case of drawing up of the Bay from several pieces, the length of each of them shall not be less than 10 m.
Mechanical characteristics of titanium wire must fully comply with the requirements specified in the table.
|Grade titanium alloy||Yield strength b MPa (kgf\mm sq)||Wire diameter, mm||B elongation, % not less|
|Vt6sv||from 1.6 to 7.0 incl.||645−845 (68−88)||13,0|
Marking the wire:
Each coil of wire shall have a label fixed to it showing:
-batch number and melting;
a hallmark of technical control;
-date of issue;
-names of the manufacturer and trademark:
-the legend of the wire;
the designation of the present standard.
Packing of wire.
Each coil of wire shall be tightly bound with soft wire of titanium in three places, packaged in a clean paper on top wrapped in burlap. Wrap Bay allowed using synthetic mesh, or plastic film whose thickness according to GOST 10354−82 is 100 — 200 µm without paper pre-packaging. Wire Packed in the Bay, tied with natural or synthetic twine in accordance with the requirements of normative-technical documentation.
|without restrictions||— 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|
