Laser alignment aims to achieve more precisely the concentration between two collinear axes or parallelism and leveling between them, so that the transmission of motion is more efficient and less equipment wear.

Laser alignment is the procedure that M Control has developed in order to achieve accuracy in performing this type of service, so that the equipment is harnessed at maximum available power, avoiding losses due to misalignment and ensuring longer service life.

Laser alignment accuracy can be at least 10 times higher than traditional alignment to milesimal values ​​(0.001mm).

Inspections aim to obtain quality parts that meet design specifications and measurements.

Inspections are performed by trained and qualified inspectors by M Control and external entities.

The main stages of inspections

  • Visual;
  • Dimensional;
  • Penetrating Liquid;
  • Magnetic Particles;
  • Ultrasound;
  • Thickness Measurement;
  • Laboratory tests such as: Chemical Analysis, Metallographic Examination, Traction Hardness Testing, Microhardness Testing, etc.

Pressure vessels and boilers shall be subjected to initial, periodic and extraordinary safety inspections as this may be considered a condition of serious and imminent risk. Upon completion of 25 years of use, upon subsequent inspection, the boilers must undergo a rigorous integrity assessment to determine their remaining life and new maximum inspection deadlines if they are still in working condition.

The implementation of boiler inspection, in addition to being legal in nature, is also a significant contribution to establishing a company security policy with regard to having SAFE and RELIABLE mode of operation. pressure must be subjected to initial, periodic and extraordinary safety inspections. When technically impracticable and by notation in the “Safety Record” by the “Qualified Professional”, the hydrostatic test may be replaced by another non-destructive testing or inspection technique which provides equivalent safety.

The recovery by welding in special equipment, aims at economy and agility in obtaining parts with quality and reliability.

All parts must be previously analyzed to identify the material to be welded.

The main parts recoverable by welding are:

  • Rodets;
  • Milling Spindles;
  • Gear Shafts;
  • Gear Gears;
  • Intermediate Mesh;
  • Straight Pinions;
  • Bi-helical Pinions.

Recovery Procedure

The recovery procedure is performed by preheating and post heating with electrical resistances. Temperature controls during heating are made through electrical panel.

The electrodes used are selected according to the base material of the part to be recovered. Therefore, the parts to be recovered must be previously analyzed.

The welding variables, such as the electric current, are controlled with pin type amperemeter.

At the end of the weld, stress relief is performed.

After recovery by welding, all parts are inspected by non-destructive testing of magnetic particles or penetrating liquid to verify the health of the part.

M Control maintains its own laboratory aiming at the efficiency of the tests and agility in the completion of the inspections.
