Description
Welding electrodes S-46.15 Universal are designed for manual arc welding of carbon and low-alloy structural steels and shipbuilding steels of normal strength with yield point up to 490 MPa in all spatial positions (especially vertical from top to bottom). Can be used for welding from both AC and DC power sources at any polarity.
Welding with rutile-type (rutile-cellulose) coated electrodes provides globular metal transfer making them suitable for welding metal plates, especially for welding thin-gage plates with short intermittent welds, the cellulose content allows vertical downward welding.
It has excellent welding characteristics such as relatively weak sensitivity to ruts, primers and surface contamination of products, stable arc, little spattering of molten metal, easy slag separation and formation of uniform surface with fine flakes of weld bead with a smooth transition to the base metal.
Characteristics
Welding position:
РА, РВ, РС, РD, РЕ, РF, PG.
Application:
Fits for welding carbon and low alloy steels.
Used in construction, ship-building, machine-building.
General guidelines:
Welding electrodes do not require baking before welding.
If an electrode is moistened, 30–60-minute baking at a temperature of 150-170 °C is required.

Precautionary measures:
Welding can emit hazardous vapors and gases to health!
Avoid breathing these vapors and gases!
Ensure proper ventilation!
Wear appropriate eye and body protection!
