The Ongoing Battle of Laser vs Arc Welding

Worker demonstrates the difference between laser vs arc welding

The age-old question has been asked for years: “Which of these two welding methods is superior?” Both have their strengths and weaknesses, so the best way to decipher which one works best for you is to look at both sides of the coin before making a decision. Read this article to its very end and find out the real winner in the laser vs arc welding battle.

The Advantages of Lasers

Lasers are more precise than arc welders – Arc welders tend to have some slag left over after welding, which can be cleaned off with a grinder or wire brush. In contrast, laser welds leave nothing behind except the clean weld itself, so there’s no need for additional post-processing or cleaning.

Lasers can be used on a wider range of materials – Lasers can use virtually any material as long as it has a reflectivity rating of at least 20% on its surface (which means that it reflects at least 20% of incoming light from any angle). This includes metals like iron and steel; non-metals such as ceramics and glass; composite materials such as carbon fiber; even organic materials like wood or leather! This isn’t necessarily true with an arc welder—they’re known primarily for working with metals because they heat up quickly and efficiently (thus causing less damage to surrounding materials).

Lasers are more durable than arc welders – A laser beam produces very little heat when compared to an electric arc produced by an arc welder, meaning that even though both processes melt metal together in order to create one continuous piece out of them there won’t be excessive heating occurring during either process which could cause unnecessary damage over time while being used regularly without maintenance checks every few months (or weeks).

Laser welding is safer than arc welding – Both processes involve handling high-voltage electricity during operation but because lasers use infrared wavelengths instead electricity currents flowing through wires into electrodes then back again out into their respective packs again whereas

The Disadvantages of Lasers

They are more expensive. While lasers are becoming more affordable, they’re still a little out of the average consumer’s price range. Arc welding machines can be found for under $500, while laser systems can cost over $10,000.

They’re difficult to use. Lasers are more complex than arc welders and require a great deal of training and practice before they can be used effectively on the job site or in the shop. This can make them less versatile than arc welders, which are easy to master by anyone with basic mechanical skills and instruction from an experienced welder.

Also, they are not as portable or durable as their counterparts

Given these reasons, it would be a lot easier for home users to reach out to someone offering professional laser welding services instead of taking on that challenge by themselves. For many of these users, this could be a deciding point in a laser vs arc welding battle.

The Advantages of Arc Welding

Arc welding is a versatile process. The heat that is generated by arc welding can be manipulated to create different types of welds. In fact, an arc welder can be used for a number of applications. Pipe joining, robotic welding, and even underwater applications. Arc welding is also a fast process. You can complete most jobs within one minute or less if your machine has the right settings and you know what you’re doing! Arc welders are also very clean machines that don’t produce much waste material while they’re working on your project.

They may not be as powerful as lasers or oxyacetylene torches but they still get the job done right! As long as you’re careful not to overheat or under-cool your metal you’ll find yourself with perfect results every time

The Disadvantages of Arc Welding

In addition to the above advantages, laser welders have some disadvantages:

Arc welding requires more skill and concentration than most other methods of welding. It is a manual process that relies on your eyesight and hand movement to control the amount of heat applied to the material.

The fumes released by arc welding are toxic. You should always wear protective equipment while working with this method (like face masks). Also, be careful not to touch your eyes or mouth while using an arc welder. The fumes may cause serious damage if they come into direct contact with either body part!

Because there’s less precision involved in this type of welding process, there will probably be some uneven areas. These mistakes will make you trouble during the assembly or alignment, and lead to needing repairs later down the line. 


As you can see, there’s no one clear winner in the laser vs arc welding match. Each type of welding has its advantages and disadvantages. It is up to you to decide which method is best for your project. Your choice also depends on what materials you’re working with and how quickly you need the job done. We hope this article has helped you learn more about two processes. Go on now, and make a more informed decision about which method is right for you!
