Electrodes OZS-12
WELDING ELECTRODES OZS-12 (diameter: 2; 2,5; 3; 4; 5 mm)
CLASSIFICATION: E46 in accordance with GOST 9466-75
LEGEND:E46 - OZS-12 - Ø - UD
E 432 - P21
TECHNICAL REQUIREMENTS:GOST 9466-75, GOST 9467-75, TU BY 100034500.044-2013
COATING: rutile
PURPOSE:
Welding critical structures of carbon and low-alloy steels having a strength up to 490 MPa, when the formation of welding seams in different spatial positions are increased requirements. Ensure easy execution of the welding process, in Vol. C. In the overhead position and tack in the formulation, as well as orbital welding joints of pipelines. Small diameter electrodes can weld from the power supply included in the domestic network.
In all spatial positions of the weld, except vertical "downward", AC and DC forward and reverse polarity
