A sample for chemical analysis grades of wire PP-NP-200Х15С1ГРТ, PP-NP-250Х10Б8С2Т, PP-NP-80Х20Р3Т, PP-NP-150Х15Р3Т2 and PP-NP-350Х10Б8Т2 taken away by draining (when overlaying the second layer with a sharp tilt of the sample fused metal of the weld pool on a copper plate, then crushing the fused metal produced grains for chemical analysis).

(Changed edition, Rev. N 1).

4.11. To determine the relative consumption of wire and wire weigh plate before and after overlaying with the error not more than 1.0 g and determine the mass spent on the welding wire and the mass of the deposited metal. After surfacing before weighing with rollers and plate carefully remove spatter and slag crust.

The ratio of the mass of wire consumed to the mass of the deposited metal is a relative consumption of wire.

5.5, 5.6. (Changed edition, Rev. N 1).

5.7. Cored wire must be transported in covered vehicles by any kind of transport in accordance with cargo carriage regulations applicable to each mode of transport.

Transportation of the wire for railway transport is carried out carload or small shipments.

5.8. Cored wire should be stored in packaging manufacturer for storage group 1 (L) GOST 15150−69.

6. MANUFACTURER’S WARRANTY

6.1. The manufacturer guarantees that the flux-cored wire requirements of this standard if the purchaser respects the conditions of storage and use.

6.2. Guaranteed storage life of wire — 12 months from the date of manufacture of the wire.

7. APPLICATION NOTES

7.1. Calcination of the flux-cored wire before applying is not mandatory. The calcination is carried out in case of occurrence of pores in the implementation of control surfacing.

7.2. Mode annealing: heating to a temperature of 240−270 °C at a speed of up to 100 °C/hour, aged for at least five hours, air cooling. Brands for wire PP-NP-18Х1Г1М, PP-NP-200Х15С1ГРТ, PP-NP-250Х10Б8С2Т, PP-NP-10Х15Н2Т, PP-NP-80Х20Р3Т, PP-NP-150Х15Р3Т2, PP-NP-350Х10Б8Т2, PP-NP-14ГСТ, PP-NP-19ГСТ, PP-NP-50Х3СТ heating temperature should be reduced to 150−180 °C.
