All stubs and spoiled electrodes shall be deposited in a locked, uniquely identified barrel. Stub pails shall be used for no other purpose.
3.4.4.1 Each foreman shall walk-down his inmediate work area at the end of each shif t or at the completion of welding activity to verify that no weld electrodes, stubs, or spoiled electrodes have been lef t out in x,
open. All stub pails shall be locked up in gang boxes or deposited in the crib (s) during the off time.
~
3.4.5 Under no' circumstances shall any filler metal be removed from stub pails or the designated receptacle for use in welding.
Such activity shall subject the welder to disciplinary action, as deemed appropriate by the LKC Project Manager.
NOTE:
Each welder must consider the work to be performed when withdrawing electrodes from the portable oven, in order to reduce waste of electrodes and to provide bett' r control of weld stubs and spoiled material.
e i
Use of low-hydrogen electrodes in conjunction with hot storage will minimize problems of hydrogen cracking. Observation of procedures will contribute c
substantially to weld quality by eliminating hydrogen, which may be introduced by water, water vapor or oil. Welders are encouraged to minimize the time between the withdrawal of electrodes from heated ovens and their use in welding.
