TSG Level 3 specialists are involved in Non-Destructive Testing training and certification services, internationally recognized through our partner company SECTOR CERT.  The training and examinations are in accordance with European, International and American standards like EN473 / ISO 9712 / ASNT, implementing advanced NDT methods and equipment.

The range of NDT Levels 2 courses in:
 

Our team of experts, certified Level III trainers are performing NDT Level III training in employer courses of certain industry sectors. All courses are offered in a specific time frame at Sector Cert.

Every candidate for the Level III should pass a Basic examination prior to any method examination. The training course imparts knowledge both of the fundamentals of testing methods and of materials, manufacturing technologies and imperfections analysis. The differences between and interconnections between all the non-destructive testing methods are also topics of this training course.

The training course meets international standards such as ISO 9712, EN 473 or ASNT’s Level III

TSG Industry Service can provide training to meet specific technology requirements and improving welder’s efficiencies. Specific client requirements are supplied leading to a Consultancy visit. Welding Courses are covering activities detailed below.

  • Equipment and Consumables used depending on the application.
  • Basic instruction in welding in the Flat and Horizontal-vertical positions leading to Positional welding in Sheet metal, Plate and Pipe.
  • Weld edge preparation depending on the metal thickness and type of joint.
  • Visual examination of welds.
  • Destructive testing of welded samples including macroscopic examination.
  • Formatting Welding procedures for repeatability of welding to the relevant EN ISO Standards.
  • Issue of Certification and if required arrangements for Pressure Equipment Directive (PED) approval are carried out by our Partners TUV Rheinland.

Welding Technologies

  • Manual Metal Arc Welding (MMA)
  • Metal Active Gas Welding (MAG)
  • Metal Inert Gas Welding (MIG)
  • Tungsten Inert Gas Welding (TIG)
  • Oxy-Acetylene Welding & Cutting
  • Orbital and Robotic Welding

Welding ProcedureSpecifications (WPS)

Welding Procedures are performed for all Welder Qualification Tests. Welder qualification tests are covered by EN 4872, EN 287:2004, and EN ISO 9606-2:2004 Aluminum Alloys.

The layouts of Welding Procedures are to EN ISO 15606 (07-09-13-14).

When Welding Procedure Approval is required, EN ISO 15614 or PED approval, arrangements can be made with our clients for witnessing and testing and the issue of all certification.

NDT is essential to many industries. Specific activities include control of welding quality, industrial parts and safety assurance of pressure vessels and pipelines.

The seminars are tailored to the client's specific needs, e.g., in relation to:

  • Durability
  • Safely loading of structures at early ages
  • Quality control of finished structure
  • Upgrading of structures
  • Locating flaws in dubious structures
  • Estimating remaining service life
  • Quality assurance of repairs
  • Monitoring of structures


Specifically addressed to the Quality, Production and Engineering Departments of companies with activity in specific industrial sectors, seminars are organized to introduce one or several NDT methods and specific techniques. In those Seminars, the principles of the methods or technique are presented; in relation to those, their limitations and capabilities are explained and discussed and, in detail, a special attention is paid to the practical applications in the suitable industrial sector.

TSG seminars focus on providing information in order to help the participants to understand and appreciate the differences between the various certification schemes available worldwide and how best to use them for their development and the progress of their respective companies.

RADIOGRAPHIC TESTING

Scientific Principles 

X-rays are used to produce images of objects using film or other detector that is sensitive to radiation. The test object is placed between the radiation source and detector. The thickness and the density of the material that X-rays must penetrate affects the amount of radiation reaching the detector. The variation in radiation produces an image on the detector-film that shows internal features of the test object.

Main Uses

  • Used to inspect almost any material for surface and subsurface defects.
  • X-rays can also be used to locates and measures internal features, confirm the location of hidden parts in an assembly, and to measure thickness of materials.

Main Advantages 

  • Can be used to inspect virtually all materials.
  • Detects surface and subsurface defects.
  • Ability to inspect complex shapes and multi-layered structures without disassembly.
  • Minimum part preparation is required.

Disadvantages 

  • Extensive operator training and skill required.
  • Access to both sides of the structure is usually required.
  • Orientation of the radiation beam to non-volumetric defects is critical.
  • Field inspection of thick section can be time consuming.
  • Relatively expensive equipment investment is required.
  • Possible radiation hazard for personnel.
