CLASSIFICATION: E100T5-D2M per AWS A5.29, ASME SFA 5.29

Select 105-D2 is a low alloy steel electrode with a basic slag system used to weld certain manganese-molybdenum steels and castings. This electrode is intended for single and multiple pass welding in horizontal fillets and the flat position.

APPLICATIONS: Select 105-D2 produces deposited weld metal of approximately 2% manganese and 0.50% molybdenum, used primarily to weld steels such as ASTM A302 GrB and castings such as ASTM A49, A291 and A735.

DIAMETERS: .045", .052", 1/16", 5/64", 3/32"

SHIELDING GAS: 75-80% Ar/20-25% CO2, 35-50 cfh

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Excellent low temperature CVN toughness.
  • Basic slag provides weld metal with low levels of diffusible hydrogen.
  • Weld deposit is suited well to match composition of manganese-molybdenum castings.
  • An excellent replacement for E10018-D2 covered electrodes.
