Onsite Nitrogen Gas Generators for Laser Welding

Why should you shut down equipment to refill the gas supply when you can easily generate the nitrogen gas your plant needs without interrupting production? Think about it!

If you are wondering why industries are switching from external gas supply to onsite nitrogen gas generators for laser welding, this article will answer your questions.

What Is Laser Welding?

Laser welding is a method of joining metals or thermoplastics together using a laser beam. The beam creates a concentrated heat source. This heat melts and fuses the workpieces, allowing a narrow, strong, deep weld joint. Laser welding is commonly used in high-volume and precision-demanding applications such as automotive and aerospace.

Laser welding operates in two fundamentally different modes: conduction limited and keyhole welding. The mode is determined by the power density distribution across the beam as it contacts the workpiece.

How Does Nitrogen Gas Help with Laser Welding?

Nitrogen gas is essential during laser welding for different purposes. First, to absorb heat from the weld zone and maintain proper weld temperature. Secondly, to create an inert atmosphere around the weld zone by displacing oxygen and moisture in the beam path. Nitrogen gas also contributes to improved weld quality and appearance as it helps reduce the formation of unwanted spatter and weld splashes and removes debris from the welding area.

Nitrogen Gas Generators for Laser Welding

Some industrial applications require high-purity nitrogen gas to achieve a quality end product. Laser welding is one of those applications. To achieve a clean and exceptional weld quality, it is important to remove oxygen, moisture, and any reactive gas in the path of the laser beam and ensure that the weld temperature is accurate and maintained throughout the welding process.

Nitrogen gas generators produce high-purity nitrogen on demand. This means there is no need to shut down your equipment to refill gas from cylinders or experience the delays that sometimes come with nitrogen cylinder delivery, resulting in loss of valuable production time.

Benefits of Using an Onsite Nitrogen Gas Generator in Laser Welding

There are a number of benefits to using an onsite nitrogen gas generator in laser welding. These benefits include:

• Cost Savings: Nitrogen gas cylinders can be expensive, and they can also be difficult to transport. Onsite nitrogen gas generators can provide a continuous supply of nitrogen gas, which can save businesses money on the cost of purchasing and transporting cylinders.
• Improved Quality: Nitrogen gas helps to prevent the oxidation of the metal being welded. This is important because oxidation can lead to poor weld quality, such as porosity and cracks. Nitrogen gas also helps to clear away debris from the welding area, which can also improve weld quality.
• Increased Productivity: Onsite nitrogen gas generators can provide a continuous supply of high-purity nitrogen gas. This can help to increase productivity by reducing the time it takes to set up and tear down for each weld. It can also help to reduce the number of welds that are rejected due to poor quality.
• Reduced Environmental Impact: Onsite nitrogen gas generators can reduce the environmental impact of laser welding by eliminating the need to transport nitrogen gas cylinders. This is because transporting cylinders produces greenhouse gasses and other pollutants.

Applications of Onsite Nitrogen Gas Generators in Laser Welding

Nitrogen gas has different applications across many industries. Let’s take a look at some of its applications in the industries below:

• Automotive: Onsite nitrogen gas generators are used in the automotive industry to weld parts such as car bodies, engines, and exhaust systems.
• Aerospace: Onsite nitrogen gas generators are used in the aerospace industry to weld parts such as aircraft bodies, engines, and landing gear.
• Machinery: Onsite nitrogen gas generators are used in the machinery industry to weld parts such as machine tools, robots, and conveyor belts.
• Medical: Onsite nitrogen gas generators are also utilized in the medical industry in welding parts such as surgical instruments, medical implants, and prosthetics.
• Others: Onsite nitrogen gas generators are also used in a variety of other industries, such as the electronics industry, the food industry, and the construction industry.
