Filed:

Nov 17, 1980

Appl. No.:

6/207665

Inventors:

Charles C. Pease - Vincentown NJ
Eugene P. Schaeffer - Marlton NJ

Assignee:

Omark Industries, Inc. - Portland OR

International Classification:

B23K 920

US Classification:

219 99

Abstract:

Apparatus and methods for replacing or repairing missing or damaged abrasion resistant wearbars utilized in high velocity cyclone boilers. A retrofit wearbar having an aperture therein is utilized in conjunction with an end weldable stud wherein the wearbar and stud are placed in position over a damaged wearbar or against the boiler tube in the case of a missing wearbar and the stud end welding technique utilized to fuse the wearbar and stud in place with the damaged wearbar or boiler tube in the case of a missing wearbar in situ. An arc shield is utilized which has a projection from the weld fillet cavity thereof which cooperates in conjunction with the aperture of the retrofit wearbar to provide alignment of the stud in the wearbar and prevent shorting of the stud to the wearbar during the welding cycle.

Abstract:

An insulation hanger for supporting a compressible insulation blanket upon a supporting wall which is formed of three pieces, the first of which is an end weldable stud welded to the supporting surface and upon which the blanket to be secured is impaled. The end weldable stud includes a plurality of annular grooves of reduced cross section providing a shoulder at the juncture between the groove and the body of the stud. A flat washer like blanket retainer is utilized which has a keyhole aperture which permits the retainer to pass over the stud through a larger hole to compress the blanket and thereafter to be moved translationally to an aperture of size approximating the groove to interlock the blanket retainer with the shoulder of the stud. A retainer lock is positioned over the stud between the blanket and the retainer and, through various configurations, locks the blanket retainer against translational movement relative to the stud preventing unintentional disengagement of the blanket retainer from the stud.
