Material:Welding Electrodes

Welding electrodes are the "sticks" in "stick welding".

They are consumed during the welding process as they melt and fill the newly created joint.

Most welding electrodes are not just bare metal but are covered with auxiliary substances that protect the hot weld against rapid oxidation. What isn't released as a gas will stay behind as slag (Schlacke) and can be removed with a slag hammer and wire brushes.

Types

Here's a list of electrodes we are sharing in the metal workshop or have experience with (incomplete):

• Fincord E5122 RR6
  • diameter: 2.5 mm
  • length: 350 mm
  • coat material: rutile (thick)
  • suggested donation: 65 ct ^[1]
  • very hot, can burn holes into approx. 1 mm thick steel

• Fincord E5122 RR6
  • diameter: 2 mm
  • length: 250 mm
  • coat material: rutile (thick)
  • suggested donation: 50 ct ^[2]

(information to further decipher the meaning of the electrode nomenclature according to DIN 1913 can be found here)

"Fincord" electrodes are supposed to be nice for unexperienced welders as they usually don't need to be baked and the slag falls off the weld by itself. ^[3]
