How Laser Cutting Works

Laser cutting gives you the ability to create intricate cuts in metals like stainless steel and aluminum. In addition to precision, the computer guidance system found within a laser cutting system means you can perform the same cut repeatedly at high speeds.

Laser Cutters

There are two types of laser cutters used by the industry:  CO2 lasers and fiber lasers. While CO2 lasers were the standard equipment for many years, they tend to be inefficient for cutting metal, as the material absorbs much of the heat. 

In contrast, fiber lasers have a shorter wavelength, allowing for sharper cuts due to a narrower kerf. 

How Lasers Cut Metal

Laser cutters work by focusing a high-intensity light beam into a very narrow point. The laser beam begins at a diameter of about ¾” and ends at a cutting diameter of about 0.008”. It is reflected from mirror to mirror to direct the beam towards a focusing lens or a curved mirror, depending on your specific laser cutter. 

 Once the beam hits the focusing device, it passes through a nozzle that helps to channel a flow of laser-cutting gas, which is usually compressed nitrogen or oxygen. 

As the beam hits the metal, it quickly heats the surface, melting or vaporizing the metal. With oxygen, the cutting process is much faster, but it produces more slag on the sides of the cut. Nitrogen slows down the cutting process but results in much smoother cuts.  

CNC Laser Cutters

With CNC laser cutters, a computer controls the path of the laser cutting, allowing you to create intricate patterns quickly and easily. You simply create a CAD/CAM file, which is then programmed into the cutting software. This program then cuts the piece automatically. This process can be repeated as often as necessary.

 Laser cutting is a quick, efficient way to create custom metal components. Amtex Precision has the equipment and training to tackle any metal fabrication project. Contact us today to learn more!

Common Methods for Welding Stainless Steel

Stainless steel is an alloy that is composed of iron, carbon, and at least 10.5% chromium. It’s not the most difficult metal to weld, but it has some unique properties that must be considered when welding.

In this post, we’ll cover the three most common methods for welding stainless steel, including TIG welding, MIG welding, and resistance welding.

TIG welding

Tungsten inert gas (TIG) welding is a type of arc welding that uses low heat, making it ideal for thinner materials. The actual mixture of the gas can vary depending on the specifications of the finished product, but typically, it includes a mixture of argon, helium, hydrogen, and nitrogen. 

The finished product can be protected from oxidation and corrosion through a single-sided welding process that creates backing gas protection between interior and exterior welds. TIG welding is the most common method used for stainless steel.

MIG welding

Metal inert gas (MIG) welding is a semi-automated process that allows welders to access hard-to-reach areas or complex structures. 

MIG welding uses an argon-rich shielding gas and other gases such as helium, oxygen, and carbon dioxide. MIG welding allows two pieces of material to be joined solidly and can be used to ensure the stability of a finished product.

Resistance welding.

Resistance welding (often called “spot” welding) simply uses electrical current to fuse metal edges together. This can be useful for materials with a low melting point. An experienced welder can complete the job without distorting the rest of the material. Because the equipment is so versatile, it can be used on a variety of project types.

The Difference Between Ferrous vs Non-Ferrous Metals

There are dozens of different types of metal, which can make it difficult to distinguish one from another. While there are many ways to analyze a metal’s characteristics, it is easiest to start by dividing them into broad categories. After that is complete, you can begin to hone in on specific characteristics and capabilities.

Perhaps the simplest method is to sort metals into ferrous and non-ferrous categories. Below, we will discuss the difference between these two metal types and why it is important to categorize them in this manner.

What Is Ferrous Metal?

If metal is categorized as being “ferrous,” it simply means that it contains iron. Some common examples of ferrous metals include:

  • Cast iron
  • Wrought iron
  • Alloy steel
  • Carbon steel

Ferrous metals are generally used for industrial applications. Shipping containers, railroad tracks, commercial tools, and even industrial pipes typically use ferrous metals. The presence of iron in these metals makes them more durable than their non-ferrous counterparts.

What Is a Non-Ferrous Metal?

As you might have guessed, non-ferrous metals do not contain iron. They have actually been used for a much longer period of time than ferrous metals. Some commonly known non-ferrous metals include:

  • Bronze
  • Tin
  • Copper
  • Lead
  • Zinc
  • Aluminum
  • Gold
  • Silver

If ferrous metals are more durable, you may be wondering why non-ferrous materials have been used for so much longer. The primary reason is due to their malleability. The crude forging methods used in centuries past made it difficult to work with ferrous metals. The softer and more malleable non-ferrous metals were much easier to shape into various goods.

Why Does It Matter?

When designing a metal-based product, it is important to understand the benefits of each metal type. For example, if you need your product to be non-magnetic, then you will need a non-ferrous metal. On the other hand, if your goal is maximum durability and strength, then you will want to use a ferrous metal.

How the Pandemic Is Spurring Reshoring Efforts

It’s strange to imagine those few months of 2020 where most were blissfully unaware of the impending chaos that is the Coronavirus Pandemic. The virus was first noted in December of 2019, but it wouldn’t be until March that the World Health Organization would declare it a global pandemic. 

Since then, the world has changed in countless ways. Some of the biggest changes will reveal themselves as more years go by, but one noticeable effect is a massive push in reshoring efforts from companies worldwide.  Continue reading How the Pandemic Is Spurring Reshoring Efforts
