The term "usability" is used indefinitely by many welding operators, but the decision of the relative difficulty of welding is slightly different according to the operators.
In this paper, we explain our view on the "usability."
From the result of analysis of the usability of welding electrodes, we consider that the usability can be decided by 8 factors which are as follows :
(1) stability of arc, (2) fluidity of slag, (3) *uniformity of melting, (4) penetration, (5) hardness of cleaning slag, (6) state of top of coated electrode in welding, (7) spattering, (8) slag-cvered state.
