Titanium welding wire is produced in degassed and pickled condition. Its ovality shall not exceed the limiting deviation. Its surface shall be clean, light-colored, without any undertones, unetching or dark spots. Traces of broaching, small risks, rolls of depth not more than those given in the table are allowed.
|Diameter of VT20-1 wire||The depth of penetration of defects in VT20-1 wire should not exceed|
Note. Individual defects are possible on the surface for wire diameters up to 3 mm - up to 0.1 mm. At Ø > 3 mm - up to 0.2 mm. During metallographic control, the number of macro-shears with exceeding the depth of defects should not exceed 10%. The defects or surface impurities can be repaired by etching Individual coils can be etched and re-degassed.
The wire is supplied in coils with an outer diameter of up to 900 mm. Such wire should not have splayed turns or bends over 100°. Curliness of the wire after annealing is not considered to be a defect. The weight of the coil is up to 50 kg. If the coil is made up of several parts, length of each part should not be less than 10 m.
The coil is tied up tightly with a soft titanium wire in three places and packed into a clean paper, wrapped with sacking or synthetic cloth, or polyethylene film with thickness according to
Mechanical characteristics of the welding wire should meet the requirements specified in the table.
|Grade of titanium alloy||Tensile strength b MPa (kgf/sq.m.)||Wire diameter, in mm||Elongation coefficient b, %, min|
