Abstract
A weld wire for storage on a spool of weld wire. The weld wire has a substantially linear cast in the form of an undulating curve that generally lies in a single plane. The undulating curve is a succession of generally semi-circular sections having a generally fixed radius of curvature. The linear cast is formed on the weld wire prior to the weld wire being wound on the spool of weld wire. The linear cast is at least partially retained on the weld wire after the weld wire is unwound from the spool and during the feeding of the weld wire through a welding machine.
Claims15
A weld wire for storage on a spool of weld wire, said wire having a substantially linear cast in the form of an undulating curve generally in a single plane, said linear cast formed on said weld wire prior to said weld wire being wound on said spool and at least partially retained on said weld wire after said weld wire is unwound from said spool, said cast having a generally fixed radius of curvature in the range of about 15-40 inches.
A weld wire having a desired imparted shape memory for storage on a spool of weld wire, said weld wire having said shape memory imparted on said weld wire at least partially prior to said weld wire being wound on said spool, said shape memory substantially lying in a single plane wherein said shape memory is generally a waveform having a maximum amplitude for each half cycle, said half cycle having a radius of curvature of at least about 15 inches.
A weld wire for storage on a spool of weld wire, said weld wire having a shape memory that is at least partially imparted onto said weld wire prior to said weld wire being wound on said spool and at least partially retained on said weld wire after said weld wire is unwound from said spool, said shape memory imparted substantially in one plane alone a longitudinal length of said weld wire, said shape memory generally in the form of a waveform, said waveform having a maximum amplitude for each half cycle, said half cycle having a radius of curvature of at least about 5 inches.
A weld wire for storage on a spool of weld wire, said weld wire having a shape memory that is at least partially imparted onto said weld wire prior to said weld wire being wound on said spool and at least partially retained on said weld wire after said weld wire is unwound from said spool, said shape memory imparted substantially in one plane alone a longitudinal length of said weld wire, said shape memory generally in the form of a wave form, said wave form having a maximum amplitude for each half cycle, said half cycle having a radius of curvature of at least about 60 inches.
A weld wire for storage on a spool of weld wire, said weld wire having a shape memory that is at least partially imparted onto said weld wire prior to said weld wire being wound on said spool and at least partially retained on said weld wire after said weld wire is unwound from said spool, said shape memory imparted substantially in one plane along a longitudinal length of said weld wire, said shape memory generally in the form of a waveform, said waveform having a maximum amplitude for each half cycle, said maximum amplitude of each half cycle having a deviation of less than about 6 inches within one cycle of said weld wire.
