Graebener Plaka Weld Seam Opening Machines

For perfect welding performance, the preparation of the plate welding seam opening must be done accurately and correctly. Graebener® plate weld seam opening machines offer you the most effective and economical solutions to achieve the best results. Benefit from our technical expertise based on years of experience and master high-speed, precision, and reliability in processing all welding seam geometries.

Overview

Graebener® weld seam opening machines are designed based on our many years of technical expertise. You can benefit from the extensive experience we gained as our customer and partner in our own pipe factory between 1974-1997. Thanks to this experience, we know that high precision in processing plate edges can only be achieved if the plates remain welded throughout the entire processing time. Especially in large-format plates, your Graebener® plate weld seam opening machine will further increase the economic efficiency in plate edge processing.

Main application areas include shipbuilding, wind tower construction, bridge construction, shipbuilding, and equipment manufacturing. In addition, our customers also include plate rolling mills and steel service centers.

Compared to alternative plate edge processing methods, the advantages of milling technology are much greater. We fully utilize these advantages.

OUR SOLUTIONS ARE EXTREMELY IDEAL FOR A VARIETY OF PLATE SIZES.

ADVANTAGES

All Graebener® plate weld seam opening machines have a proven design that operates reliably even under the most challenging conditions. We avoid using additional turning devices that may be subject to wear or malfunction. Even after years of use, your Graebener® machine will continue to operate with high accuracy, speed, and reliability. Benefit from the technical advantages of your Graebener® plate weld seam opening machine.

• The milling process does not cause additional stress on the plate due to heat – recyclable milling chips dissipate the heat

• You obtain a metallic shiny surface

• High parallelism on milled edges

• You can benefit from our excellent plate clamping system:

  • High adaptability rate

  • Uniform weld seam opening

  • Less wear on milling tips

  • Less vibration

• Plates are automatically measured

• Low environmental impact due to low noise, dust, and heat emission

• Both U-groove seams and chamfering are possible

• Electronic copying of plate waves provides a center-focused milling profile

• Depending on the machine type, plates can be placed inside the machine, no need for overhead crane

• You can also process coated plates depending on the design
