DEFINITION

Classification: 228/15.1

(under the class definition) Device including means for deforming (and defined below) the work, filler, or flux wherein the deformation occurs prior to the fusion bonding.

(1) Note. The term "deformation" for this subclass and the indented subclasses requires a permanent change in the shape or size of a member without removal of material therefrom. See the Class Definition and Lines With Other Classes and

Within This Class in Class 72 for a definition of metal deformation.

(2) Note. A single, integral instrumentality (e.g., welding bell, may be used to deform and then fuse the work.

(3) Note. Placement into this subclass or the indented subclasses requires only that there be some deformation of a work part prior to fusion of that work part; the additional occurrence of simultaneous deformation is immaterial. For example, a patent to a device for making helical tubing, wherein a leading portion of a blank is deformed into a convolution of a tube and then fused to a following portion of the blank prior to the deformation of that following portion, is included herein.
