Material Testing Machines for Energy, Oil, Gas and Wind
From pipeline welds to the composite materials used in wind energy, mechanical testing helps engineers evaluate strength, deformation and joint performance. DAK testing systems connect these material questions with the specimen handling, measurement and test control your laboratory needs.
Your testing application
From energy-sector materials to meaningful test results
Metals and welded joints
Assess the tensile behaviour of base metal, weld metal or a specimen taken across a joint. Weld location and specimen orientation determine which region is evaluated. Bend testing provides a different view of a welded joint under deformation.
Wind-energy composites
Tensile, compression, flexural and shear tests characterise laminate specimens used in blade-material development. Fibre direction, laminate construction and loading arrangement are central to comparing results between material systems.
Structural adhesives and bonded joints
Evaluate the bond between selected substrates using a loading arrangement suited to the joint. Lap-shear, peel and fracture tests answer different questions about strength and how a bonded assembly separates.
Plastic pipes and fusion joints
Pipe-wall specimens and specimens containing a fused joint address different properties. Identify the pipe material, wall geometry and joint type so the test loads the region that matters to your quality or development programme.
Gaskets and sealing materials
Compression, recovery and relaxation studies describe different aspects of sealing-material behaviour. Start with whether the result concerns deformation under load, recovery after unloading or the change in force over time.
Materials under repeated loading
A material that meets a single-load strength requirement may also need evaluation under repeated loading. Define the loading pattern, required cycles and measured response when discussing fatigue studies for energy-sector materials and components.
Configure the test
Build the setup around the result, not just the peak load
Specimen geometry and load introduction
Include the specimen drawing, gripping length and any weld, tab or bonded region. Tensile grips, compression fixtures and bend supports must introduce load in the intended direction without substituting a different test arrangement.
Strain, extension and displacement
Metal yield, laminate strain and joint movement are different measurement requirements. Choose the measurement location and range alongside the grips; crosshead movement is not interchangeable with strain measured on the specimen.
Temperature and time
State whether specimens are tested at room temperature, after conditioning or during controlled-temperature testing. Long-duration loading also brings test-control, fixture and measurement requirements that should be included in the configuration discussion.
DAK testing systems
Choose a platform around your laboratory
A universal testing machine supports a range of material and joint tests through the appropriate grips, fixtures and measurement. Select the machine and accessories together for the methods your laboratory will run.
DAK flagship
Series 7200 Universal Testing Machine
Our flagship universal testing platform brings flexible test programming, specimen setup and measurement together for laboratories working across metals, polymers, composites and bonded materials.
Series 9000 Universal Testing Machine
A universal testing option for established tensile, compression, flexural and related methods. Compare its published working space, force range and control approach with your laboratory requirements.
Repeated-load and long-duration programmes
Fatigue, sustained loading and temperature-dependent studies have distinct requirements. Share the intended loading history and environment so the complete system can be discussed alongside your routine material tests.

Before you specify
Two distinctions that shape an energy test programme
Material specimens or complete structures?
A laminate coupon, bonded subassembly and complete wind-turbine blade have different loading and space requirements. Tell us which scale you are testing so the discussion starts with the right machine configuration.
A one-time strength result or behaviour over time?
Peak force alone does not describe stiffness, fatigue response or load retention. Specify which results support your engineering decision and whether the programme includes cycling, holds or temperature control.
