Choosing Welding Filters For Metal Inert Gas Welding

To choose the right welding filter for metal inert gas welding (MIG welding), it is key to match the industrial filter rating to the metal type and airflow. Dynamic Filtration Ltd., a leading manufacturer of industrial filters, filter elements, custom filters, and more in Waterloo, Ontario, explores these selection factors in this blog.

 

 

What To Consider When Choosing Welding Filters For MIG Welding?

 

Matching The Filter To The Metal Type

 

The most common types of metals or alloys that are processed using MIG welding include mild steel, carbon steel, stainless steel, and galvanized steel. In the case of mild and carbon steel, the welding filter must have a MERV rating of around 13 to 16, as the MIG welding process will produce iron oxide and generic metal dust. With a welding filter in this range, it is easy to filter out these contaminants.

 

In the case of stainless steel, MIG welding creates hazardous particles such as hexavalent chromium, manganese and nickel fumes. As for galvanized steel, the welding process releases zinc oxide, which is equally toxic. In both these instances, a HEPA welding filter would be a better choice, as it will ensure worker safety.

 

Airflow Considerations

 

The welding filter being selected must also take airflow considerations into account. The cubic feet per minute capacity (CFM) must match the size of the workshop where the MIG welding process is conducted. So, in the case of larger facilities, multiple filters or filter stations might be required.

 

 

Conclusion

 

To conclude, choosing a welding filter for MIG welding must take all these factors into account for effective filtration.

FAQs:

 

Should HEPA welding filters be paired with pre-filters?

 

Yes, it is beneficial to pair HEPA welding filters with pre-filters, as they will handle the large particles and extend the service life of the main filter.

 

How often should welding filters be replaced?

 

Most welding filters should be replaced every 3-6 months for optimal filtration performance.
