Tips To Choose A Laser Welding Machine

Invented in the 1970s, handheld Laser welding machines broke into the market in the 1990s. Their demand has faced an upward trend over the years. The sheer benefits of laser welding machines cannot be downplayed. They serve high efficiency and massive revenue production. You’ll also enjoy high precision and ease of operation among others.

You don’t have to empty your savings on protective gear. You can use laser welding spectacles and be just fine.

Compared to the 90s, the market is larger than ever, as everyone seeks to create a niche for themselves. Likewise, many producers are presenting these powerful machines from all directions. This too has a fair share of setbacks, the major one being getting the best option. But this guide features tried-and-true tips for sifting the best laser welding equipment. Read to the end!

Tips For Choosing The Best Laser Welding Machine

  1. Type of Laser Welding Machine You Need

To make the best shot, you need to understand each type of laser welding machine. Understanding how each type works will make the process even easier.

  • Gas laser welding: This type of welding uses carbon dioxide gas to create energy in the form of heat and light. An electric charge passes through a carbon dioxide-filled chamber. The current excites the atoms which in turn releases energy. The energy is normally high enough to create laser beams used for welding.
  • Solid-state welding: Uses a solid-state medium to create beams. Neodymium-doped yttrium aluminum garnet; Nd: Y3Al5O12 is the most common solid-state medium used. The laser beam passes through transmitters and amplifiers. Crystalline rods and special lenses are also used.
  • Fiber laser welding: This is among the latest welding types. Hence its accuracy and high effectiveness. This technology uses fiber optics to generate and transmit laser beams. Fiber laser welding machines are designed to be compact because fibers are flexible.
  1. Continuous or Pulsed Laser Welding

In continuous laser welding, laser beams flow in a continuous stream. This technology comes in handy when different types of welding need to be applied. Besides, you can bank on it for fast welding.

Laser pulses are smaller packets of energy that divide laser beams. Pulsated laser beams are applicable for high-intensity energy welding such as spot welding. Besides, they are a good option for effective, high-precision, narrow, and deep welding.

  1. Welding Compatibility

Fiber laser welding machines are mostly applicable for thin and thick metal processing. Fiber laser welding offers a high 30% wall plug efficiency (WPE). This results in deeper keyhole penetration. It also facilitates higher keyhole tolerance, and a higher welding speed.

Carbon dioxide laser weld machines are the best for thick metal parts. They offer a 5-10 wall plug efficiency.

Nd: YAG laser welder machines are the best for forming structures on steel. They have a high power output of more than 2KW. This renders a welding speed of 16mm/s which is generally lower than carbon dioxide laser welds.

  1. Material Compatibility

How compatible and reflective is the metal in question? Laser welding machines can work with materials like thermoplastics, metals, and composites. So make a list of materials you’ll most likely work with. The less shiny the surface the more it is compatible with any laser welding equipment.

Fiber laser weld machines are best used for metallic materials. For instance aluminum, brass, copper, stainless steel, silver, and gold. Carbon dioxide laser welds go with most non-metallic materials. They include acrylics, rubber, wood, fabric, and leather. Besides, CO2 also works well with thermoplastics like plastics and composites.

  1. Industry Application

Which industry do you intend to use the laser welding machine? Here are two options:

  • Robot laser welding: uses computer-controlled robots to weld materials in 3-dimensional space. They have high efficiency and operation speeds. This makes them a must-have for large-scale production.
  • Handheld laser machines: Designed for small and medium-sized businesses. They come in three forms: manual, compact, and semi-automatic. It is also ideal for spot welding and continuous welding seams.


So far, we hope to have equipped you with the right skills to get yourself started. Buying the right welding laser machine for your specific needs doesn’t have to be hectic. Just stick to the above tips as you try to remain in budget. Remember you don’t have to empty your savings to get the most expensive option. There’s literally something for everyone.

The cost of laser welding equipment varies with country of production and the types. Generally, fiber laser welds are slightly more expensive than other types. Their shipping costs and other taxes may skyrocket the prices. The distance of the destination country may also increase the shipping cost.
