The welding sector is facing an ecological turning point!

A market that employs over 20.000.000 professionals, with a turnover of over 40 trillion euros, that wants to evolve, innovate and embrace a greener processing policy.

What are the problems with the highest environmental impact?

And what are the possible solutions?

Let’s see them together.

The number of people employed as Welding, soldering, & brazing workers has been growing in the last 5 year at a rate of almost 5%, in the usa alone from 580,520 people in 2018 to 609,457 people in 2019.

We face two major challenges in the 21st century:

digital transformation and ecological transition.

Ecological transition is an essential objective for humanity.

Digital technology is one of the greatest transformative forces of our time.

Lasermach is continuously working to use its innovative optical technology to develop breakthrough products while minimizing its environmental impact. 

EcolEner ®: Sustainable Ecological Energy Saving Technology

ECOLENER ® Photon Saving Technology

Sustainability is emerging as an important approach that manufacturing companies employ to improve their economic profitability and competitive advantage by enhancing environmental performance.
Consistent with the contemporary aspects of ecological responsibility, specific forms of ECOLogical ENERgy saving used in our PhotonWeld Laser Welding Machines (with ECOLENER ® technology), do help positively to improve drastically the relationship between an environmental sustainability orientation and environmental performance.

What are we doing for a more environmentally friendly welding?

The first step towards greener welding is to improve the energy efficiency of the tools used.

An action with a dual value: reduction of emissions and increase in productivity of each welding process.

One of the solutions, today, seems to be the use of electronic parts instead of electrical components for the construction of welding generators: we talk about energy savings of up to 25~35% compared to conventional welding units. Given the advance of increasingly smaller and more portable equipment, this goal seems to be fullfilled already in the last years and all the offered equipment is fully electronical.

But the biggest energy savings can be obtained by changing the conventional welding to the very high efficient laser welding, which can reduces the energy consumption till 90%! Thats real savings!!!

Emissions are reduced through the use of new consumable products (such as electrodes), which are technologically advanced and less subject to the release of fumes and dust. With laser welding we use only wire out of the same metal as th eone welded as consumable, which is only melted and does not need special treatment or covers. Much less fume with laser Welding;

Eco-Friendly Welding solutions and Practices for 2022 and Beyond

The industrial world needs welding. As the popularity of metal structures and constructions rises, more skilled welders are required. However, welding is an energy-intensive process and not so friendly to the environment.  In large factories, a lot of energy used by welding and some polluating fumes are also produced.

As the world moves towards protecting the environment, the welding industry can not leave behind. The welding industry must make a great effort to reduce their ecological footprint!  Small and big things can help to do this  and there are several eco-friendly practices that welders can engage in to reduce their carbon footprint. To do that, welders need to look at the entire welding process to understand which part of the process affects the environment more. From there, the welder can reduce their carbon footprint by tweaking the:

  • Welding speed
  • replace high energy consuming older welding systems with the latest "GREEN" welding systems
  • The raw materials
  • Processing time
  • System costs
  • Filler metals, and
  • Seam quality
  • But mostly look for Energy saving technology in welding like laser welding in general. Our supplementary Ecolener Photon saving technology gives you even a bigger advance in saving energy.

There is a need for a reduced carbon footprint in all industries. The welding industry can reduce its footprint by reducing the energy they use by making the process more efficient and eliminating the use of older energy hungry welding systems. Older systems lead Flux, and flux  leads to the release of gases and fumes that are harmful to the environment.

To save the environment, welders around the world need to educate on the above eco-friendly techniques and to replace their energy hungry systems by modern energy saving welding systems like our PhotonWeld.   Individuals as well as companies, have a role to play in saving energy, making the air cleaner and the environment safer for the generations to come.

Reduced HAZ - Reduced Heat-Affected-Zone

Almost invisible Heat Affected zone

Most of a laser’s energy goes into making the weld itself, with very little wasted on heating the surrounding area. Less waste means lower utility bills.

ECO-EFFICIENCY

Time to reflect

EcolEner Technology means decreasing the carbon footprint of our customers by reducing emissions in their operations with the help of our products.

This is a long-term, maybe never-ending, mission.

At Lasermach, we work hard to reduce the emissions caused by our own produced welding machines.

EcoLener 976nm:

The new Green Number

Our EcoLener 976nm pumped high efficient fiber laser Sources achieves 85% optical efficiency with a Wall-Plug efficiency of almost 50%, which is much higher than any other wobble laser Welding Machine.

 

976nm pumped fiber laser achieves 85% optical efficiency

The 976nm pumping solution has obvious advantages and will gradually become the mainstream of the market.

The current laser welder equipment in the market are mainly water-cooled solutions, that is, heat is taken out of the laser through the external circulation of the chiller. Lasermach's PhotonWeld focuses on continuous discussion and innovation based on 976nm technology, combined with the high photoelectric conversion efficiency of 976nm Creatively solved the problem of air-cooled refrigeration capacity, launched the air-cooled 976nm technology for the first time in the industry, solved the power consumption and portability issues, and once again lead the technical development direction of fiber lasers.

The 976nm semiconductor laser is applied to the high-power fiber laser in the industrial market. Due to the elimination of the nonlinear effect of the fiber, nearly 85% of the light-to-light conversion efficiency is achieved, the whole system is weakly affected by the ambient temperature, and the reliability of the semiconductor laser itself is higher. Many advantages will be more and more valued and welcomed. In the long term, with the scale application of the 976nm fiber-coupled module, it is believed that the product technology level will continue to improve, and low-cost 976nm wavelength locking on components will become a reality.

The 976 nm chip is more reliable than the 915 nm chip and has a longer life expectancy!

The 976nm semiconductor laser pump source as a core device also improves the reliability and life expectancy of the fiber laser machine.

As far as the semiconductor laser itself is concerned, the 976 nm chip is more reliable than the 915 nm chip and has a longer life expectancy. Although the GaAs epitaxial crystal material has a slightly better photoelectric conversion efficiency in the 915 nm, the photon energy is lower due to the longer wavelength of 976 nm, and the cavity surface damage threshold of the high-brightness semiconductor laser chip under high current operating conditions is improved. In other words, the 976nm chip has a lower probability of cavity surface optical catastrophic damage (COD) than the 915nm band chip, and the chip itself is more reliable. Therefore, the 976nm semiconductor laser pump source as a core device also improves the reliability and life expectancy of the fiber laser machine.
