Welding electrodes of TML-1U
Electrodes for welding alloyed heatproof by staly TML-1U
For manual arc welding of the equipment and pipelines from staly 12XM, 15XM, 20HML, 12X2M1, 12H1MF, 12H2MFB, 12H2MFSR, working at a temperature up to 5400 With and elements of surfaces of heating of a copper from staly 12H1MF, 12H2M1, 12H2MFSR and 12H2MFB irrespective of working temperature. Welding in all spatial provisions, except vertical from top to down, a direct current of the return polarity.

|Recommendations - Electrodes provide high resistance of metal of a seam to formation of a time when lengthening an arch, allow to carry out welding in narrow cutting. To carry out welding a short arch, to smooth out edges before welding.
Repeated calcination of electrodes before welding 380÷420 ºС during 1,0÷1,5 hour.
