Titanium welding wire produced in degassed and etching condition. Its roundness must not exceed tolerances. Its surface must be clean and bright, with no shades of tint, neprotravov or dark spots. Traces broaches, small risks, sunsets deeper than shown in the table.
|The diameter of the wire VT20−1 St.||The wire brand VT20−1 St. depth of the defect must be no more than|
Note. On the possibility of a separate surface defects with a diameter of the wire up to 3 mm — 0.1 mm. When Ø> 3 mm — 0.2 mm. During metallographic control Macrosection amount in excess of the depth of defects shall not exceed 10%. Correct defects or surface contaminants by etching the etching is allowed to separate bays with repeated degassing.
Wire comes bays with outer diameter up to 900 mm. This wire must not be stuck together turns or bends of more than 100 °. Curl the wire after annealing, is not considered marriage. Coil weight — 50 kg. If the bay is made up of several parts, the length of each of them must not be less than 10 m.
Bay tightly ligated soft titanium wire in three places and packed in clean paper, wrapped burlap, synthetic cloth or plastic film, thickness according to GOST 10 354−82 100 — 200 microns without paper packaging. Packaged Bay ligated string of regulatory documents, respectively.
The mechanical characteristics of wire must conform to the requirements specified in the table.
