Destructive Testing
Tensile Test
This experiment is conducted to determine the mechanical properties of metallic materials and welded joints under a static load.
Yield strength (ReH)
Maximum load (Fmax)
Tensile strength (Rm)
Face lengthening
Mechanical properties are determined in this way. In our laboratory, a Universal Tensile-Compression tester is used for the aforementioned test.
Microscopic Examination
Etching is the process of examining an etched or unetched sample under a microscope with magnification ranging from 50 to 500 times.
Microscopic experiments are used to reveal microscopic features of welded joints, usually by examining their cross-sections. The aim of microscopic examination is to reveal properties such as hot cracks, cold cracks, lamellar tearing, voids, lack of fusion, solidification structure, and grain structure.
Notch Impact Test
This experiment is conducted to determine the fracture energy of a material under dynamic loads. After the notch impact test specimen fractures, the fracture surface is examined to gain insight into the type of fracture. These fracture types can be ductile fracture, brittle fracture, etc.
Compression test
External forces acting from the surface inwards are called compressive forces and create compressive stresses. It is considered the reverse of the tensile test. The strength values of brittle materials are generally determined by compressive testing. It is particularly used in determining the strength of materials such as brick, concrete, and similar materials.
In compression tests, cylindrical or cubic specimens are placed between two parallel plates, and the deformations caused by the applied force are measured using an extensometer.
Longitudinal Tensile Test at the Source
Tensile testing is a method of determining the strength properties of materials under static (non-impact) load by pulling them until they break at a constant temperature, and obtaining a stress-strain diagram during this process.
Microscopic Measurement of Coating Thicknesses
To measure the coating thickness of metal surfaces, a cross-section is taken perpendicular to the coating. The thickness of the coating is then measured using a microscope. Surface treatment (polishing and grinding) is generally not required.
Bending test
This test is conducted to determine the fracture energy of a material under dynamic loads. After the notch impact test specimen fractures, the fracture surface is examined to gain insight into the type of fracture. These fracture types can be ductile fracture, brittle fracture, etc. The fracture energy is calculated in joules, and this value varies depending on the specimen dimensions and test temperature. In our laboratory, this test can be performed using an impact testing machine between +10 and -80 degrees Celsius.

Z-Test
This process involves taking a sample perpendicular to the product surface (in the direction of thickness), tensile testing until fracture, and determining the Z quality based on the percentage reduction in cross-section at the fracture site.
Flattening Experiment in Pipes
This experiment is used to determine plastic deformation by flattening test specimens cut from pipes by compressing them at specific ratios.
Flattening Experiment in Pipes
This test involves flattening test specimens, cut from the end of pipes at a distance of 50-100 mm, by pressing them along the diameter at the ratios specified in the standard. The aim is to determine their plastic deformation capability.
Shore AD Hardness Test
B. The method used to determine the hardness value of plastic or flexible materials is called Shore hardness measurement. It is used to measure the hardness of polymers, elastomers, rubbers, fabrics, and sponges. Shore-A and Shore-D are most commonly used in measurements. They are classified according to the indenter and the weight used.
Damage Analysis (DT-NDT)
Damage analysis identifies the root cause of failure mechanisms and offers preventative measures to prevent recurring incidents. Whether you are a manufacturer or operator, disruptions caused by damage can impact your processes and profitability. In the worst-case scenario, damage can pose risks to employees, the community, and the environment. This can damage your brand reputation and lead to legal action.
Macroscopic Examination
It is a physical examination performed by magnifying visible objects using a lens system.
Macro examination is the inspection of an etched or unetched test specimen with the naked eye or under low magnification.
Macroscopic experiments are used to determine the macroscopic characteristics of welded joints, usually by examining their cross-sections. This process is carried out by visually and/or optically inspecting the prepared surface before and after etching.
Hardness Tests
The hardness of metals can be defined as their resistance to plastic deformation. A hardness test measures the resistance of a material to a harder material pressed against its surface.
Nut Stripping Test
Load testing of nuts is performed using our Instron 5989 electromechanical device with the help of the apparatus provided by the customer, at the load values specified in the 898-1 standard, for tensile and compressive loads up to 60 tons.
Anchor and bolt components undergo tensile tests, while nuts undergo proof load tests.
The tensile test for bolts shows whether the bolt body provides the required strength. In the load test for nuts, the nut is loaded up to the test load, then released and rotated by hand to check if it functions properly.
Transverse Tensile Test at the Source
Tensile testing is a method of determining the strength properties of materials under static (non-impact) load by pulling them until they break at a constant temperature, and obtaining a stress-strain diagram during this process.
Fracture Test
The aim is to fracture test specimens extracted from welded joints and examine the fractured surfaces. The test is performed to obtain information about the types, sizes, and distributions of internal defects on the fracture surfaces, examples of which are given below.
Pores
Cracks
Melting deficiencies
Lack of influence
Solid remains
