Coil Joining
Taylor-Winfield was one of the first Companies to provide fully automated coil
joining systems incorporating resistance welding or arc welding and post induction heating processes. Taylor-Winfield has established itself as an innovator in this field
We are the world leader in coil joining with more ways to solve customer needs. Using over thirty basic designs, Taylor-Winfield engineers can create any type of weld configuration. All you have to do is tell us the coil widths, the thickness and type of steel, and the speed at which you need to process. We deliver welding solutions to produce directly abutting joints or overlapping joints. We can also deliver the work handling equipment required to feed steel through the coil joining process, assuring a totally integrated solution
SELECTION WELD TYPE LINE APPLICATIONS
In selecting the equipment to meet your specific coil joining requirements, the primary considerations are strip width, thickness and type of steel, and the speed at which it is to be processed.
With little more than this basic information, Taylor-Winfield engineers can determine the required weld strength and the joint configuration that will achieve it. In addition, they will see that the joint is completed within the available time frame and that is flows smoothly through subsequent processing and recoiling.
Basically, there are two ways in which the strip ends, after shearing can be arranged for welding: directly abutting or overlapping.
In a directly abutted joint, the finished weld is approximately the same thickness as the strip. This type of joint flows smoothly through processing and can be rolled or recoiled without marring or damaging adjacent coil wraps.
An overlapped joint, when completed, will range from full double thickness down to nearly single thickness. Double-thick joints are used primarily for threading a new coil though the processing line and are most often removed prior to final processing.
In addition to the two basic joining configurations, Taylor-Winfield offers a patented Prep/Lap joining technique that combines the advantages of both: smoothness and flatness, plus exceptional joint strength.
Each technique has many variations that meet a wide range of special requirements. The most popular weld configurations and their typical applications are profiled in the diagram at right.
