GUILD HMA Shearwelder
Guld HMA Shearwelder

The world’s most precise thin-gauge shearwelder, the semi-automatic HMA/DMA Shearwelder™ is ideal for thin-gauge strip processing lines where coil ends can be positioned manually from the shear to the weld station. It is capable of handling most materials up to 20″ (500 mm) wide and thicknesses from .005″ (0.12 mm) to .160″ (4.0 mm).


The HMA and DMA Shearwelder are machines that join two coil ends together by using either TIG, MIG, PLASMA, or LASER welding. The coil ends can be overlapped or butt welded depending on the application. These machines are designed for use on either start/stop or continuous lines such as:

  • Coil Buildup
  • Tube/Pipe Mill
  • Stamping
  • Others

Why Choose Guild

Since 1958, Guild International has led the industry as a world leader in designing and manufacturing coil joining and strip accumulating machinery. We continue to meet the rigorous engineering and design expectations that our clients have come to value. Guild’s equipment continues to increase productivity and yield on thousands of installations around the world on virtually all types of coil processing lines and materials.

Our team of designers and sales engineers are dedicated to providing innovative products and services that exceed our customers’ expectations to help make them more productive and profitable.

Our promise is simple: To take the time to come to know and understand our customers’ needs for coil processing and strip accumulating, and to then provide those customers the most appropriate, high quality equipment to increase their productivity and profit.

Adjustable features make the HMA and DMA Shearwelders easy to operate. The trailing coil end is sheared, then positioned in the weld station. The leading end of the second coil is sheared and then positioned in the weld station. Welding is automatic and features a variable-speed, solid-state DC motor drive and control.

Other features include reversible shear knives and weld backup bar. The HMA Shearwelder features hand operated shear and weld clamps while these items on the DMA are hydraulically operated. Edge alignment guides have hardened, replaceable faces and are adjustable. The automatic weld carriage is supported on four ball bushings for precise alignment.

The tab welding option modifies the welder for precision welds on narrow, thin gauge materials. It is used primarily on single traverse wind or press feed lines, where a perfect edge-to-edge weld is required, on narrow strip, from about .187″ (4.75 mm) to 7″ (180 mm) wide.

An exclusive feature allows the operator to make consistent high quality edge-to-edge welds on the narrowest and thinnest materials. Extra-long, completely contained side guides are also provided to assure proper strip alignment in the machine.

Guild International offers a complete line of coil end welders for almost any application. Our patented product line includes Zipwelders(TM), resistance welders, semi-automatic shearwelders, and strip accumulators including Supercoils®, Superloops(TM) and Continuous Coils. Guild also produces a full line of rotary and cropshears along with uncoilers, speed funnels, and flatteners. Plus, our team of engineers will help you determine your needs and ensure proper equipment design and compatibility with your existing equipment.
