Delta NEU

Welding Fume Extraction for the Aerospace Industry

Any welding process involves increasing the temperature until melting point is reached, and the pieces of metal are welded together, inevitably generating welding fumes. Delta NEU selects the best solution together with the on-site operator to customise the welding fume extraction system.
The key components to achieving appropriate collection at source is a suitably positioned fume extractor with a well designed hood, appropriate airflow, and a careful welder who places the hood so that the hazardous fumes are sucked away from his or her breathing zone and are also prevented from spreading throughout the premises

Example of this Application at One of Our Customers

Welding fume extraction system in several boxes of an aerospace parts manufacturing unit.

Welding fumes are made up of gas and sub-micron size dust particles.

Respiratory risk
If inhaled by an operator, the fumes can penetrate the alveolar ducts of the operators' respiratory systems, causing inflammation of the lungs. The quality of air in the production premises of the transport industry has an effect on productivity and can be a contributing factor to absenteeism due to occupational diseases.

To reduce occupational exposure to fumes in the aerospace sector, welding stations in particular are equipped with a welding fume extraction system. This is made up of an adapted (enclosed or induction) capturing system, a smoke removal unit, and a system which processes the fumes prior to discharging them outside the building.

Example of the aerospace sector
In the aerospace sector, the device used to extract fumes must primarily have an ergonomic design as this type of work requires high precision on the part of the operator. Therefore it is essential to establish whether or not welding fume extraction will be required. The capturing system must also be protected from the risk of ejections; and the same is true for the operator who must wear PPE. Another major criteria to bear in mind when choosing the right industrial smoke extractor is the noise level.
