How do you select electrodes for welding?

How do you select electrodes for welding?

Factors for Selecting the Right Stick Electrode

  1. Base metal properties.
  2. Tensile strength.
  3. Welding current.
  4. Base metal thickness, shape and joint fit-up.
  5. Welding position.
  6. Specification and service conditions.
  7. Environmental job conditions.

What ER70S 2?

Pinnacle Alloys ER70S-2 is a copper-coated solid wire designed for welding carbon and carbon-manganese steels with tensile strength up to 73,970 psi (510 MPa).

What does the 2 stand for in a 7024 electrode?

The “2” in 7024 electrodes means flat or horizontal only. 7024 electrodes are also known as a drag rod. They are best used for laying down a lot of metal quickly. The 2 in 7024 indicates these electrodes are rated for flat and horizontal position fillet welds.

What does the 2 in E7024 mean?

The AWS classification of SMAW electrode, E7024 what does the “2” stand for? Flat/Horizontal Position.

How electrodes are selected?

The type of electrode used depends on the specific properties required in the weld deposited. These include corrosion resistance, ductility, high tensile strength, the type of base metal to be welded, the position of the weld (flat, horizontal, vertical, or overhead), and the type of current and polarity required.

What is the difference between ER70S-6 and ER70S-2?

Type ER70S-2 is the most popular Tig rod for welding carbon and low alloy steels… It is a triple deoxidized steel welding wire used for both tig and mig welding applications. Type ER70S-6 is a very popular mig welding wire that can also be purchased in cut lengths and used for Tig welding.

What does the 70 stand for in ER70S-6?

18 ER70S-6 is standard MIG welding of carbon steel. 70 refers to the use of the post-deposited metal welded wire minimum tensile strength of 70ksi (480MPa). S is a solid acronym. Meaning that for solid core wire. In addition to S, but here as standard C (composite) indicates that the wire for the metal core.

What does the 60 in E6010 stand for?

For example, E6010 means 60,000 pounds per square inch (PSI) tensile strength and E10018 means 100,000 psi tensile strength. The next to last digit indicates position.
