Welding electrodes T-590
product.uv
- before surfacing, it is necessary to clean the welded part from dirt, rust, oil
- it is not recommended (in order to avoid cracking) to perform surfacing of steel parts in more than two layers, of cast iron - one layer
- for carbon low-alloyed steels, the previous layer can be welded with Monolith RC, АНО-36 electrodes, for manganese-alloyed steels with UONI 13/55 Plasma electrodes
- the presence of cold (hardening) cracks is not a defect, but an indicator of high hardness , ledeburite-carbide structure of the deposited metal
product.sv
- ensure the production of a stable deposited layer, which has high resistance to abrasion by various solid particles
- allow to carry out welding of cast iron products and welding of casting defects of steel 110G13
- production of deposited metal from special metallurgical purity and low hydrogen content
- surfacing coefficient: 0.20...0.22 g/A•min
- consumption of electrodes per 1 kg of deposited metal: 1.4... 1.8 kg
Т-590 brand electrodes are intended for surfacing of elements operating in conditions of mostly abrasive wear with minimal impact loads. They are used to surfacing the teeth of excavator buckets working with abrasive wear in sandy soil, road machinery knives, plow blades, discs and blades of agricultural machinery cultivators, mixer screw blades, aspirator blades, crusher cheeks, etc. Surfacing by the above-mentioned Т-590 electrodes the elements have excellent durable and strength operating characteristics

Surface deposition should be carried out in the lower and inclined positions on a direct current of reverse polarity, "+" on the electrode, with an arc voltage of 23 – 27 V, narrow rollers or with small oscillations of the electrode. Also, surfacing can be carried out with alternating current from a transformer with an open circuit voltage of 70 V.
