Non-destructive testing technology that employs the physical principles of conventional ultrasound and promotes the optimization of its resources through electronic controls of separate elements in a single structure, which pulse individually forming a mosaic of crystals, enabling changes in the sonic beam. Typically, pulses are generated in groups of elements to improve sensitivity, increasing or reducing the beam opening which allows better beam focusing.

Technique used to detect and size internal discontinuities in the material, which is based on the physical principle of diffraction of ultrasonic waves. The inspection is computerized and allows acquisition and recording of inspected data, the images generated are presented in shades of gray and the weld volume is inspected in a single scan. This technique is very efficient in detecting and sizing cracks, regardless of their guidance.

The Liquid Penetrant test is considered one of the best test methods for detecting surface discontinuities in materials free of porosity, such as ferrous and non-ferrous metals, aluminium, metallic alloys, ceramics, glass, certain types of plastics or organosynthetic materials.

Magnetic particle testing is used to detect surface and subsurface discontinuities in ferromagnetic materials. Defects such as: cracks, welding cracks, cold joints, inclusions, cold drop, double lamination, lack of penetration, folds, segregations are detected.

The manufacture of increasingly complex equipment, with countless components, requires that measurements are also increasingly precise. Therefore, Dimensional Control applied to the object of a project, throughout its manufacturing stages, is a fundamental process to guarantee the fidelity of the measurements and dimensions of the equipment, as well as the materials, their components and their appropriate locations.

Our topography professionals use an optical precision instrument that checks vertical and horizontal angles, known as a total station and theodolite, this professional establishes the orientation of equipment with auxiliary landmarks, where he performs the location and projection of anchor bolts, location and leveling of industrial equipment, positioning and leveling of metal structures, ladders, pipe supports, alignment and plumb of concrete structures.
