"METHOD OF ATTACHING FITTINGS TO A CYLINDRICAL WELL SCREEN" ABSTRACT Improved method of attaching sleeve-like fittings to a wrapped wire well screen by welding is faster and stronger than prior methods, provides better mechanical sealing, and eliminates changes in the width of the screen slots. The fitting is axially slotted where it is intended to telescopically overlie several wraps of the well screen. The application of weld beads in the axially directed slots causes the fitting to shrink into tight mechanical contact with the well screen and prevents the enlargement of the slots in the well screen which is possible when a circumferentially oriented weld bead is applied.
