PURPOSE:

Electrodes CT-28, designed for welding equipment from heat-resistant and heat-resistant nickel-based alloys brands XH78T, HN70VMYUT and the like, as well as well as dissimilar metals (pearlite and chromium steel swith nickel-based alloys). In all spatial positions seam direct current reverse polarity.

CHARACTERISTICS Electrodes:

Coefficient surfacing - 10,0-11,0 g / A • ch.Proizvoditelnost deposition (for a diameter of 4.0 mm) - 12,0-14,0 kg / ch.Raskhod electrodes per 1 kg of deposited metal - 1.5 kg .

ABOUTSOBYE PROPERTIES:

Electrodes DH-28 provide a weld metal with high heat resistance (oxidation depth at 1000 ° C for 3000 hours is 0.1 mm) and high-temperature strength (creep rupture strength of 100 MPa at a temperature of 565 ° C for 10000 hours).

WELDING PROCESS FEATURES:

Welding is made narrow rollers width not exceeding 2.5 diameter of compulsory elektroda.Svarka after calcination: 190-210 ° C; 1 h.
