Dr. Loose GmbH is a globally active engineering services company in the field of

Finite Element Analysis for welding simulation, manufacturing simulation, thermal simulation and welding consulting.


We draw on more than 17 years of experience in our special field, the numerical manufacturing simulation for welded and heat treated components.


With manufacturing simulation, we can support our customers in the product development process from the early stages of planning by providing our expertise to solve manufacturing-specific challenges.


We are happy to numerically validate your welded assembly before the first arc is ignited.

Our engineers solve welding problems for you with the help of simulation methods and support you in planning and designing your welded structures, determining the welding sequence, the clamping and tacking concept and the heat guidance.


Our welding engineers attach great importance to process-reliable production with optimum results for minimum tolerance deviation.


With our many years of experience in solution strategies for industrial applications and scientific research results in the field of welding optimization, we are a competent partner for the construction industry, light and heavy engineering, shipbuilding, plant engineering, rail vehicle construction and the automotive industry.


In addition, our welding engineers offer solution-oriented consulting for development engineers and welding technicians from industry and welding companies.
