The DMI Shearwelder™ is our economical choice for wide strip coil end joining. This machine is capable of handling strip up to .625″ thick and up to 85″ wide. This semi-automatic shearwelder is specifically designed for applications where the coils are either too thick or too wide to be conveniently welded manually.


The DMI Shearwelder are machines that butt weld two (2) coil ends together by using either TIG, MIG, PLASMA, or LASER welding. The DMI Shearwelder is designed for use on either start/stop or continuous lines such as:

  • Pickling
  • Rolling Mill
  • Anneal & Pickle
  • Tube/Pipe Mill
  • Coil Prep
  • Galvanizing
  • Coil Buildup
  • 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.

DMI Shearwelders can shear and butt weld material ranging from about 0.060″ (1.50mm) up to about 1″ (25mm) thick, and as wide as necessary. Recent machines have been used for strip up to 86″ (2,150mm) wide. Any weldable material can be used on these machines. Since the coil ends must be flat for proper operation of these machines, the use of a flattener is normally recommended.Depending on the process line requirement, the weld can be used as a transport weld, being removed at the exit end of the line, or it can be used for coil buildup. Butt welds created using this machine are usually nearly as strong as the parent material.

The DMI Shearwelder is ideally suited as a low cost option meant for use in wide strip coil end joining.

The DMI Shear Welders are capable of shearing strips with thickness of up to .625-inch and up to 85-inch width. Available in a semi-automatic operation, the DMI Shear Welders have been specifically designed for use in situations where the coils are either excessively thick or wide that reduces the manual coil welding. The DMI Shear Welders that are capable of butt welding two coil ends make use of Tungsten Inert Gas (T.I.G.) welding, Plasma welding, Metallic Inert Gas (M.I.G.) welding, as well as the Laser Beam welding methodologies.

The DMI Shear Welders are designed to provide a faster and accurate way to join coils on all types of strip processing lines. The DMI Shear Welders are ideally suited for use in either start/stop or continuous line processes such as pickling, rolling mill, coil prep, stamping, coil buildup, anneal & pickle, as well as galvanizing. The DMI Shear Welders are ideally suited for use with a wide range of weldable alloys such as stainless steel, carbon steel, aluminum as well as other types of alloy metals. These Shear Welders which have a long service life help the users to improve their working efficiency, and generate the desired products. The DMI Shear Welders depending on the process line requirement, can not only be used as a transport welding system that can be removed at the end of line, but can even be used for coil buildup process.

The DMI Shear Welders are ideally suited to deliver butt welds with capabilities that makes them almost as strong as their parent material, making them ideally suited for use in welding any type of weldable material. The DMI Shear Welders are capable of shearing and butt welding alloy metals, and other metals available in the thickness range of 0.060-inches to up to 1-inch thickness and as wide as possible. With the latest advancement in technology, the latest DMI Shear Welders machines can strip alloy metals, and other metals with a width of up to 86-inches. The DMI Shear Welders work well when operated alongside a flattener; the flattener keeps the coils flat. Its important that coil ends be kept flat as it helps in proper operation of the shear welders.

The uniqueness of DMI Shear Welders is that the gauge range for each application can be changed according to the requirements. The gauge range not just determines the rake angles, upper and lower shear blade clearances, but also tonnage capacity. The DMI Shear Welders can also be designed as per the requirement and specification given by the customers. The DMI Shear Welders are sometimes called coil end joiners, strip welders, end welders, coil splicers, shear and end welders also, but they do the same thing that is shear strip ends, as well as butt welds coil after coil. The DMI Shear Welders are also used to provide a smooth ductile weld, so that the newly joined coils can easily pass through a tube or pipe mill.
