Spit­fire

The revolution in submerged arc welding systems.

Submerged arc welding technology (SAW) is an arc welding process with a high melting rate using an endless wire or strip electrode. The process, which can be automated extremely well, is primarily used for welding long seams with very high quality.

With the Spitfire technology, AWS Schäfer is building on years of experience in the field of submerged arc welding processes. This new and innovative technology enables a higher deposition rate and sets new standards in efficiency and precision. Today's increasing challenges and requirements in the pipe industry demand new solutions and approaches. We at AWS Schäfer have succeeded in developing a product that offers you commercial and ecological added value.
Spitfire is the world's first submerged arc welding process that uses inductive welding wire preheating to significantly increase the deposition rate within a submerged arc welding process without the need to invest in additional individual wires on the welding head. This not only saves on consumables in the welding process, but also on production time.

Advantages

  • The energy input per wire is kept constant using the welding parameters
  • Excessive heat load on the welding head is avoided
  • The melting performance achieved is reflected in more weld metal volume per time unit
  • A higher volume per cross-section at a constant feed rate
  • A constant volume in the cross-section at a higher traversing speed

Our quality pledge

The AWS principle

Meeting individual requirements

Your requirements are unique. We work with you to develop a machine that is precisely tailored to your needs. We meet your requirements with tailor-made concepts.

Using knowledge successfully

Take advantage of our knowledge! Thanks to our many years of experience and our technical expertise in global pipe production, we take all relevant country-specific standards and guidelines into account when developing your machine.

Support at all levels

We are also at your side after your machine has been manufactured. Whether it's on-site assembly, training your employees or adapting to new requirements - we provide you with reliable, long-term support.

Spitfire technology

The Spitfire technology from AWS Schäfer revolutionizes submerged arc welding (SAW) technology with innovative wire preheating. Your advantage? This world's first and new process significantly increases the deposition rate without the need for additional wires on the welding head. This saves you both time and materials. Spitfire technology gives you more precise and efficient weld seams, meets the ever-increasing demands of the industry and offers you both economic and ecological benefits.

Induction bending technology

Induction bending technology from AWS Schäfer offers you precise and efficient bending of pipes, T-beams and profiles, ideal for the petrochemical, oil and gas sectors as well as power plant construction. Our machines enable you to make precise bends with minimal wall thickness reduction and high dimensional stability. Our patented technologies ensure efficient and user-friendly handling, while integrated systems ensure precise geometries and increased product quality. You benefit from reduced costs and increased efficiency.

Hydroforming technology

AWS Schäfer's hydroforming technology is ideal for the production of complex components such as T-fittings and bends in the oil and gas sector. A pipe is precisely formed in a hydraulic press using a liquid medium. The process enables the use of different materials and wall thicknesses in the same tool and offers maximum dimensional and repeat accuracy. Shorter process steps. Low energy consumption. Short cycle times. Hydroforming offers you economy and efficiency throughout the entire production process!

Clad pipe technology

AWS Schäfer's clad pipe technology offers you a cost-effective solution for pipes that have to withstand extreme corrosive conditions in the oil and gas industry. Hydromechanical cladding firmly bonds a corrosion-resistant liner and a carbon steel pipe using high-pressure fluid. This technology enables flexible material combinations, such as ferritic and austenitic steels, as well as aluminum or titanium as liners. The clad pipes produced on our machines offer high corrosion resistance and precise dimensional tolerances, combined with low susceptibility to defects and low investment costs.

Submerged arc welding (SAW)

The submerged arc welding systems (SAW) from AWS Schäfer offer you maximum efficiency and quality when welding long seams! Our systems can be configured flexibly with up to five welding heads and energy-saving inverter technology. You benefit from a user-friendly control system that integrates all common welding power sources and an innovative welding powder supply system that focuses on sustainability and high powder quality. These tailor-made solutions improve your productivity and reduce your operating costs at the same time.

Pipes and pipe mill technology

Whether sheet metal measuring system, sheet metal bending press, pipe calibrating press or pipe end milling machine - our pipe mill technology solutions offer maximum precision and reliability for your demanding pipe production projects! Our modern sheet metal measuring and forming systems as well as end processing machines are in use worldwide and can be seamlessly integrated into existing or newly planned pipe mills.

Custom-made machines

If standard machines do not meet your requirements, our custom-made machines come into play! Our team of engineers can look back on numerous successful projects in the implementation of individual machines for forming and processing steel and pipe products. We also carry out retrofits, upgrades and conversions of machines and systems.
