Description:
TML-3U are electrodes with a basic coating, designed for welding equipment and steam pipelines made of steel grades 12MX, 15MX, 20MKhL, 12Kh1MF, 20KhMF1, 15Kh1M1F, 15Kh1M1FL and similar, operating at a temperature of no more than 565 °C, and heating surface elements made of steel grades 12Kh1MF, 12Kh2MFB and 12Kh2MFSR regardless of the operating temperature, as well as welding defects in elements made of the same steels. Special properties TML-3U electrodes allow welding in a narrow groove with a total bevel angle of 15 degrees and ensure high resistance of the weld metal to pore formation during arc extension.
