Назначение и область применения
TML-1U electrodes are designed for heat-resistant steels. TML-1U welds steam pipelines from steel grades 12MoCr, 15MoCr, 12Cr1MoV, 15Cr1Mo1V and 20CrMoVL, operating at temperatures up to 540 °C, and elements of heating surfaces from steel grades 12Cr1MoV, 12Cr2MoVSiB and 12Cr2MoVB, regardless of operating temperature. Welding with TML-1U electrodes is performed in all spatial positions of the weld with direct current of reverse polarity.
