Advantages of Conventional Welding vs Advantages of Laser Welding

There are many challenges that welders face like working under high temperatures, striving hard for precision, etc. And guess who’s got the solution? Technology. It has almost every solution to upgrade your way of the stick. But remember, upgrading welding parts is equally important. You can invest in Amada parts for complete support in adapting new technologies.

Let us have a look at two of the most common and trusted ways of seal to understand their advantages. This will help you to choose the one best to fulfill your requirements.

Conventional Welding

Invented in: 1800s.

MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) welding are the two most common forms of conventional seal. This works by using a shielding gas to create an inert atmosphere around the head. This inert atmosphere allows the welds to be isolated from other gases in the surrounding area to stop the welds from becoming porous. An electric arc heats up the metal and metal filler, once melted it joins the material together to create a strong weld.

Advantages of conventional welding

  • With laser seal, when you are welding two materials together, they need to have a good fit up due to the little to no filler used in the weld. While, with conventional welding, you can have the liberty of imperfections in fitting up to two materials by using the filler
  • Conventional Welders cost considerably less in comparison to Laser machines.
  • With a conventional seal, the chances of galvanic corrosion on a workpiece are minimized.

Laser Welding

Invented in: 1967

If talking about basic functionality, laser seal is not much dissimilar to conventional welding. The primary difference is the heat source. Instead of the arc of a MIG or TIG welder, laser welders use a highly focused laser beam (photons of light) as the heat source.

Almost everything, from electronics to medical devices to jewelry making, requires seal of some sort. Even precision in wristwatch welding requires laser technology. Amada laser consumables are the best option to choose for upgrading your seal experience.

The three types of lasers most commonly used in welding applications are:

  • Gas Lasers
  • Crystal Lasers
  • Fiber Lasers

Advantages of Laser Welding

  • Laser welding can weld a whole array of metals like carbon steel, high strength steel, stainless steel, titanium, aluminum, and even precious metals.
  • The laser weld is narrow and has an excellent depth-width ratio. This makes the weld strength much better than TIG and MIG Welding.
  • The heated area of the weld doesn’t spread to the rest of the material and this initiates rapid cooling. By this method, you can handle the materials instantly after the job is complete.
  • Laser Welders don’t require the skill that conventional welding does. Laser Welding offers a much more precise weld in comparison to TIG and MIG welding. Its works from computer input whereas conventional welding requires man force to operate the machine.
  • There is minimal deformation and shrinkage in the material due to the process used for laser welding.
  • One-sided laser welding can replace spot welding which requires access to both sides of the material, as seal needs access to only one side.
  • Due to high precision, the laser produces less scrap as there are rarely any errors.


If I had to choose between the two, I’d have to go with Laser because it provides impeccable precision and of course many other benefits too. One can use laser Welders with Amada parts and Amada laser consumables in industries such as Medical, Automotive, Aerospace, Manufacturing, etc. Laser Machines can also be portable. This helps to reduce downtime by taking the machines on site.

Conventional welding methods are suitable for most standard requirements. They do have some drawbacks though. In many instances, laser seal is an ideal method over conventional methods.
