Fume Extraction for MIG Welders: What You Need To KnowJanuary 23, 2023
Welding is a popular trade that uses high-powered electric arcs to join metal pieces together. The fumes created while welding can be harmful, especially if they’re inhaled. In this article, we’ll discuss the different types of welding and how they produce fumes, as well as how to safely extract those fumes using MIG welding fume extraction equipment.
What is MIG welding?
MIG welding is one of the most popular welding methods due to its simplicity and ease of use. In MIG welding, a wire electrode is fed into a gas-shielded arc welder and passes through a flux core and shielding gas. The MIG welder produces very small arcs that are capable of joining metal plates together.
The best way to start learning MIG welding is by reading the operator’s manual that came with your equipment. In general, there are three types of welds you can make with an MIG welder: fillet, joint and groove. Fillet welds are used to seam two pieces of metal together or to smooth out an area on one piece of metal. Joint welds join two pieces of metal together at a 90-degree angle and create an overall stronger bond than fillets. Groove welds are used to create patterns or cuts in metal.
Types of MIG welding fume extraction
There are three main types of MIG welding fume extraction systems: natural ventilation, mechanical exhaust, and chemical fume extraction. Each has its own advantages and disadvantages. Natural ventilation is the simplest system to install and use, but it can be less effective than other methods. Mechanical exhaust systems use fans to move the gas away from the welder, but they can be more expensive and require more maintenance than other systems. Chemical fume extraction systems use chemicals to remove the gas from the atmosphere. They are the most effective type of system, but they can also be the most expensive.
Fume Extraction Equipment
MIG welders produce large amounts of fumes. Fume extraction equipment is used to remove these fumes from the work area. The type of fume extractor used will depend on the welding process and the materials being welded.
The most common type of fume extraction system is a scrubber. A scrubber uses a cyclone to remove particles from the air. This system is best for welding metals that do not react with oxygen, such as aluminum.
A second type of fume extraction system is a scrubber-dryer. This system uses a cyclone followed by a dryer to remove particles from the air. This system is best for welding metals that react with oxygen, such as iron and steel.
Both systems use filters to remove small particles from the air. It is important to keep these filters clean to ensure high levels of particle removal performance.
How Does Fume Extraction Work?
Fume extraction is the process of removing volatile and harmful gas emissions from welders and other metalworking machines. This process is used to protect workers and equipment from exposure to hazardous fumes.
There are a few different ways that fume extraction works. In most cases, the gas exiting the machine is cooled before it is released into the atmosphere. This process eliminates the heat that makes the gas more volatile, which in turn reduces the chances of a dangerous explosion.
Another common method involves using a scrubber to remove particulates from the gas stream. These particulates can be very small, and can easily become embedded in plant surfaces or clothing if they are not removed. Finally, some machines use a catalyst to convert carbon dioxide into harmless water vapor.
Guidelines for MIG Welders
The use of MIG welders is a common welding process that can be used for a variety of applications. However, like any other welding process, there are certain guidelines that should be followed to ensure the safety of both the welder and the welded object.
When using MIG welders, it is important to understand the basics of fume extraction. Fume extraction systems are designed to remove particles and gases from the atmosphere while welding. The system typically consists of a filter, fan, and ductwork. The filter captures small particles such as dirt and dust. The fan forces these particles towards the ductwork where they are expelled into the atmosphere.
Before starting any welding project, it is important to ensure that your MIG welder is in proper working order. Make sure that all spark plugs are properly installed and free from oil or grease contamination. Check your welder’s amp ratings against the requirements of your project materials. Finally, make sure you have a quality fume extraction system in place before beginning your welding project
