Extraction Systems for Welding and Soldering Fumes

Depending on the method used, fumes from welding or soldering are generated when steel, stainless steel and coated or refined metals are processed. In addition to other substances, these fumes may contain health-endangering or carcinogenic particles such as chromium(VI) compounds and nickel oxides. The released particles can be classified both as alveolar dust and as inhalable dust. To minimize the welder's exposure to the resulting pollutants and to comply with statutory workplace limits, certain organizational and technical safety measures must be taken. One of the most important aspects is to ensure a favorable working position of the worker outside the immediate danger zone, as well as the reliable extraction of fumes at the point of origin.

To help you implement the necessary safety precautions, we work with you and your suppliers to analyze and evaluate the effectiveness of ventilation measures for your automated welding cells and manual welding stations. Based on this, we devise optimization measures for the cells, detection systems (e.g. food) as well as extraction systems and associated ductwork.

We also study the spread of fumes and their deposits in the production hall and derive recommendations for cleaning measures and cleaning plans.
