The TWI Diplomas in Welding Engineering were introduced by TWI as an alternative to the EWF/IIW diploma for those candidates who do not meet the access conditions.

The TWI Diplomas are also recognised by employers globally as a confirmation of a high level of knowledge, expertise, and organisational understanding of welding. They also fulfil the exacting quality requirements required for welding coordination, covering a large variety of applications, materials and processes.

The TWI diplomas follow a modular approach therefore allowing progression through the three levels of qualifications shown below:

  • Specialist level - 6 modules
  • Technologist level - 4 modules
  • Engineer level - 4 modules

Each module lasts one week and finishes with an exam.

Upon completion of each of the above, you will be awarded a TWI Diploma in Welding Engineering at the appropriate level.
