CLASSIFICATIONS: E70T-5C, E70T-5M per ANSI/AWS A5.20, ASME SFA 5.20
Select 75 is a flux cored electrode designed with a basic slag system
which provides better mechanical properties and diffusible hydrogen
levels in the weld deposit than E70T-1C electrodes. Select 75 is
intended for single and multiple pass welding of carbon and certain
low alloy steels where a minimum tensile strength of 70,000 psi
and good low temperature notch toughness are required.
APPLICATIONS: Select 75 is an ideal choice for weldments
involving difficult steels, such as high carbon and free-machining
types. It is well suited for heavy section fabrications such as
crane sections, heavy machine bases, boom assemblies and construction
equipment. Typical steels welded with this electrode are ASTM A36,
A285, A515 Gr. 70 and A516 Gr. 70.
DIAMETERS: .045", 1/16", 3/32"
SHIELDING GAS: 100% CO2, 35-50 cfh
WELDING POSITIONS: Flat and Horizontal
CHARACTERISTICS:
Better welding performance than conventional T-5 electrodes.
Slag removal and bead geometry similar to E7018 electrodes.
Low diffusible hydrogen levels.
