Denis Haase (Managing Director)

After completing his engineering studies in the field of mechanical engineering and further specialisation in the field of welding technology through further training as a welding engineer, Mr Haase acquired solid practical expertise in the field of steam boiler construction in a globally active power plant construction company. During this time, he acquired qualifications in all common non-destructive examination methods (VT, PT, MT, RT, UT). The subsequent 6-year activity as an expert at a Swiss testing organisation enabled him to acquire sound knowledge in the implementation of the Pressure Equipment Directive using various Construction Codes  (e.g. AD2000, EN12952, EN13480, ASME BPV Code).

With the recognition as ASME Authorised (Nuclear) Inspector and AWS Certified Welding Inspector, Mr. Haase has been carrying out ASME- as well as AWS-compliant certified welding inspection activities for more than 10 years and supports several certified manufacturers in Switzerland and neighbouring countries. In addition, he is active in the area of the Pressure Equipment Directive as a technical expert for the Notified Body #0090 TÜV Thüringen e.V. and as a seminar instructor.
