Welding robots are becoming increasingly popular in jointing technology. But occupational safety does not end with automating the process. Employee protection continues to play an important role. How this works is explained in our blog post on occupational safety in robot welding.

Minimizing downtimes and providing a high level of occupational & health safety with cutting machines: TheSlagger - the patented extraction and thermal cutting table - removes slag and small parts in minutes. Automated operation makes this possible.

Extraction arms are the most commonly used equipment in Germany for welding fume extraction. The correct handling is decisive with regards to effective capture of welding fumes. A high coverage rate and thus the effectiveness of occupational safety largely depend on this. We explain which standards apply for the use of extraction arms and what you have to consider during handling.

During welding, ultrafine particles are created which are breathed in or swallowed by welders. The smallest particles often cause the greatest damage. Yet, how exactly do these ultrafine particles affect the welder? And what kind of defense mechanism does the human body have? The majority of particles in welding fumes are ultrafine (ultrafine is in this context a further grading of respirable). Particles less than 0.1 microns in size are classed as ultrafine. 

A daily ration of milk against welding fumes: This used to be the be-all and end-all of occupational safety. Yet, the legend about the protective effect of milk against health damage caused by welding fumes is partially still persistent today. Yet, this is really more of an old wives’ tale than real fact.Milk against welding fumes used to be the mantra against the health consequences caused by hazardous substances during welding. Companies gifted their staff a daily ration of milk and thus considered their occupational safety duty done. Sometimes, a quarter liter of milk is said to be the required dose, other times, it is an entire bottle. This was, however, in times in which extraction technology and ventilation technology played absolutely no part yet in metal processing businesses.

If metal processing companies want to protect their employees and equipment, then filter technology plays an essential part for automated processes. Clausthaler Laser- und Werkstofftechnik GmbH agrees with this statement. After adding fiber laser cutting of pipes to its portfolio, an extraction plant cleans the air from hazardous substances using innovative filter technology.No new business area without modern filter technology: That was clear for Clausthaler Laser- und Werkstofftechnik GmbH (CLW) right from the start. Increasing cost pressures previously forced CLW to rethink its strategy.

Welding fumes affect the lungs and are toxic or carcinogenic. The health consequences for the welder depend mainly on the composition of welding fumes. Science differentiates between three effects.The hazardous substances in welding fumes created during welding are formed of several components: Basic and supplementary materials, inert gases, coatings, contamination and ambient air. Prerequisite for the formation of hazardous substances are certain physical and/or chemical processes. This includes: Evaporation, condensation, oxidation, decomposition, pyrolysis and combustion.

Every metal processor should know these days that welding fumes are harmful.  Yet, one question gets asked over and over again: What are welding fumes exactly? Just looking at the composition gives an indication of what hazards are behind welding fumes and why welding fume extraction is important.
