PURPOSE AND FIELD OF APPLICATION

Electrodes CL-39 are designed for manual arc welding with a DC of reverse polarity of heating surfaces of boiler units, as well as root passes seams of thick-walled pipelines joints of heat-resistant steel of the pearlite class 12Х1МФ and 15Х1М1Ф grades, operating at a temperature up to 585 ºС.

SPECIAL PROPERTIES

Welding electrodes CL-39 provide high resistance of a weld metal to the porosity while welding with elongated arc. They allow narrow cut welding with a common angle of bevel edge not less than 15º. The welding seam is durable and resistant to corrosion. Resistant to high temperatures. The low oxidizing capacity of the metal deposited with CL-39 ensures a smooth transition of the alloying metal into the base metal of the product. Thus, the welding seam is heat-resistant and not subject to hot cracks formation. Welding should be made with a short arc; clean the edges before welding.

APPLICATION CONDITIONS

Deposition rate factor: 9,5 g/A.hr. Electrode consumption per 1 kg of deposited metal is 1,6 kg. Designed for welding in all the spatial positions except the vertical down one.
