Health & Safety EXTRACTING THE BENEFITS
extraction nozzle, which was mounted directly on each robot’s welding torch. All four extraction nozzles were connected to a single centralised high vacuum system through flexible hoses that were attached to each welding robot and by pipelines installed under the floor and along the walls of the premises negating any obstruction of activities in the workshop. The heart of the system is Nederman
welding of railway bogies, but faced challenges to fit both welding robots and fume extraction systems within the limited space of the premises. A compact Nederman fume extractor allowed the customer to achieve a safe and healthy working environment, more efficient production and energy savings. Like in every welding operation, it is necessary to ensure that the welding
A
Nederman customer in the welding industry built a new repair depot for robotic deposit
fumes generated in the process are removed. The challenge in this case was the minimum free space in the workshop. The extraction system needed to be as compact as possible to fit in the depot together with the four simultaneously working welding robots. In addition, the extraction devices must not interfere with the welding process, or during loading and unloading operations of the workpieces. To achieve this a solution was developed
with welding fume extraction carried out directly from the source by using a special
FlexPak1000, that has a capacity sufficient for simultaneous operation of all four extraction points. Each nozzle is equipped with a TAV 50 MV-W valve to automatically start/stop the extraction when a particular robot is operating to save energy. In addition, the system has SA-GW swing arms with vertical drops for vacuum cleaning of metal dust, swarf and for general cleaning. The solution enabled the customer to achieve a safe and healthy working environment due to clean air in the facility, more efficient production, and energy savings by the automatic control of the system.
