, B) electricity flows from the positive cathode to the negative anode.
C) electricity flows at random between the anode and cathode.
D) electricity stops flowing once the arc is established ANS >>> A
2. The SAW fluxes are ANS >>>
A) classified on their own. They have their own separate designation.
B) not classified. Only the wire is classified.
C) classified in conjunction with the welding wire forming an electrode/flux
designation.
D) all classified with EM12K wire. Use of other wires would require companies
to perform testing to verify desired properties. ANS >>> C
