Basic Principles of Liquid Penetrant Inspection
Liquid penetrant inspection (LPI), also known as dye penetrant inspection (DPI) or penetrant testing (PT), was first developed in the early 1940s to detect flaws on the surface of materials.…
Weld Qualification Testing
A weld sample is produced prior to commencing the final welding of the product. All welding variables are controlled and recorded when welding the weld sample or coupon. These welded coupons are …

LMATS provides Visual inspection services on various engineering structures and products from its several Australian Laboratories. LMATS comprises a team of experienced Inspectors, Metallurgist, Engineers, NACE/AICIP/WTIA certified Inspectors and NDT Personnel. The combination…
The advantages and disadvantages of advanced NDT
Simple, conventional inspection methods such as ultrasonic thickness testing can provide a useful, fast, low-cost method for assessing materials. However, in comparison with advanced NDT, such methods are generally less…
Non-destructive material verification uncovers hidden manufacturing process flaws
In recent months, manufacturing in the U.S. has shown consistent gains in terms of employment, productivity and wages. In April 2017 alone, an additional 6,000 manufacturing jobs were added to the economy, and associated…
Crack Management Series
Within the past year, the American Petroleum Institute (API) published the first edition of API RP 1176, a recommended practice for assessment and management of cracking in pipelines. While the API…
3D Modeling & BIM Using Laser Scanning
If you caught our last blog post here on storage tank inspections using laser scanning technology, you may have wondered about some of our other services. One of the most common uses of laser scanning is…
Pulsed Eddy Current for corrosion
A break-through 2-year study in 2002 on the direct costs associated with metallic corrosion in nearly every U.S. industry sector initiated by NACE International and mandated by the U.S. Congress in 1999 as…
CiBot carburization measurements: The process that allows non-destructive inspection on radiant coils in the furnaces
Carburization is the formation of metal carbides in a material as a result of exposure to a carbon containing atmosphere. In service, it can result in loss of mechanical properties…
Geo-hazard Monitoring of Pipelines using Strain Gauges
Introduction Pipelines are sometimes subjected to various geo-hazards such as long wall mining subsidence and slope movement. A commonly practiced method to reduce stress in such situations is to expose…
