Taylor-Winfield has been a world leader in the supply of coil joining welders since the beginning of the steel industry. Our welders include the most advanced process control and data gathering systems required by the most sophisticated process lines built throughout the world.

T-W has the solution to your coil joining needs and more. Choose from our complete line of welding machines, many of which are customized for unique customer requirements:

CORE COMPETENCIES

  • Flash Butt Welders
  • Narrow Lap Resistance Mash Seam
  • Laser-Seam or Spot Welding
  • Multi-Gun Spot
  • ARC- Continuous Seam or
    Butt Welding
  • Others

When selecting coil joining equipment, there are four primary requirements. They are:

  1. Strip Width Range
  2. Strip Thickness Range
  3. Strip Material Type
  4. Welding Speed

Taylor-Winfield engineers will then determine the required weld strength and joint configuration that best suits your need and processing time. The diagram below shows different machine types, the weld that is produced, materials that can be joined and types of processing lines they are best suited for.
