Laser alignment

Laser alignment measures shaft position and supports controlled correction to reduce forces, vibration, seal wear, and coupling stress.

What the service evaluates

The field questions this service is built to answer.

  • Horizontal and vertical offset
  • Angular misalignment
  • Soft foot and base condition
  • Thermal growth and movement allowance

Inside the engagement

What happens before, during, and after the site visit.

A focused service should answer a defined technical question, not merely produce readings. Good execution preserves operating context, measurement settings, limitations, and the chain of reasoning from observation to recommendation.

For laser alignment, that means beginning with horizontal and vertical offset, working in the context of motor-pump trains, and preserving enough evidence to support as-found alignment record.

Field-use caution

A field measurement is evidence, not an automatic diagnosis. Access, loading, configuration, history, and complementary checks determine what the result can support.

Behind each reading

What the field team is doing while the instrument collects data.

Preparation, safe access, repeatability, context, and technical review make a measurement useful.

  1. 01

    Confirm equipment condition, lockout, and train geometry

    Primary focus: Horizontal and vertical offset. Expected record: As-found alignment record. Typical setting: Motor-pump trains.

  2. 02

    Check soft foot, looseness, and movement constraints

    Primary focus: Angular misalignment. Expected record: Correction moves. Typical setting: Fans and blowers.

  3. 03

    Measure and correct alignment

    Primary focus: Soft foot and base condition. Expected record: As-left alignment values. Typical setting: Gearbox-driven equipment.

  4. 04

    Document final values and tolerances

    Primary focus: Thermal growth and movement allowance. Expected record: Observed base or movement concerns. Typical setting: New installation and post-repair setup.

Service record

What should appear in a complete field record.

  • The asset, audience, or system boundary and the decision being supported
  • The relevant operating state, access conditions, source records, and known limitations
  • The observations or results related to angular misalignment
  • The comparison, technical reasoning, confidence, priority, and alternative explanations
  • The owner, timing, verification method, and trigger for escalation or follow-up

Analyst review

What gets challenged before the report is issued.

  • Was the evidence collected under a representative and documented condition?
  • Does another indicator support—or conflict with—the first conclusion?
  • Could access, setup, data quality, environment, or operating state explain the result?
  • Is the proposed action proportionate to condition, consequence, and uncertainty?
  • What new evidence would confirm that the action worked?
FIELD NOTE
Alignment quality depends as much on the base, pipe strain, and movement strategy as on the laser reading.
