Repair of mesh electrode spaced from electrode pan

摘要

Electrodes such as mesh electrodes can be in configurations where they are separated from electrode back pans by standoffs. The mesh electrodes are very adherently secured to the standoffs. When the electrodes are in need of repair, removal and refurbishing can be a problem. There is now disclosed a method of electrode repair which in large part retains original structure by first removing the mesh electrode and then at least substantially the top of the standoff. A replacement standoff assembly is placed against the retained portion of the original standoff and secured thereto. Refurbished or new electrode mesh can be adhered to the resulting replacement standoff. This may include welding of mesh electrode strands utilizing weld nuggets which are substantially the size of the strands. The refurbishing technique can maintain original separation distances between the back pan and the electrode. The structure provided can be in an "as new" condition without need for repair at an off site location from where the electrode will be used.
