Overview:

Macro testing is a visual method of inspection providing an excellent sectional view of the item inspected. Commonly used for welder qualification and certification, it is also used as an integral part of failure analysis.

Description:

Advantages:

• Provides an excellent cross sectional view. Interpretation can be verified by an independent source.
• Samples can be sent to the laboratory for analysis from remote regions.
• Result is readily and permanently recorded.
• Inspections can be carried out “On-Site” with minimal equipment.

Disadvantages:

• A high degree of polishing is required.
• The preparation of the etching fluids involves handling of dangerous substances.

Typical Applications:

Commonly used on:

• Shafts
• Castings
• Welded Areas
• Support Rails
• Earthmoving Equipment

Capability:

Typical metals tested and etching fluids used on this site:

• Carbon and low alloy steel
• Austenitic Steel
• Aluminium Alloys
• Copper Alloys

• Nitric acid & Alcohol
• Nitric & Hydrochloric acid
• Nitric, Hydrochloric and Hydrofluoric acid
• Nitric acid & Distilled water

Hardness Testing can be carried out with minimal disruption to normal operation with the compact and portable Proceq Equotip. Material hardness data can be recorded in Rockwell, Brinell, or Vickers scales and used as a guide to material type and heat treatment. The Proceq Equotip can be operated in any position from 0 – 180 degrees.
