Working energy-efficiently saves money and protects the environment. In welding technology, this means not only lower energy consumption but also a more sustainable use of resources - leading to better production processes and a stronger eco-balance. Schnelldorfer Maschinenbau supports energy-efficient work with highly developed welding systems that combine modern technologies with economic responsibility.
The basics and importance
What does energy-efficient welding technology mean?
Energy-efficient welding technology broadly covers all measures that reduce energy consumption during welding. These include the selection of the welding process, the shielding gases used and the digital control of process parameters. The focus here is on the entire welding process: from the current flow in the arc to the control of the welding speed. The aim is to use energy only where it is actually needed, without compromising on seam quality or process reliability.
Why welding requires a lot of energy - and what needs to change
Welding processes require high temperatures, which are generated by electric arcs, plasma or concentrated jets. This consumes a lot of energy - especially with outdated devices or poorly set parameters. The pressure on the industry to reduce climate-relevant emissions and work in an increasingly energy-saving manner is growing.
However, the key lies in innovation: new, energy-efficient processes such as cold metal transfer (CMT) significantly reduce power consumption by controlling the heat input. The future therefore lies in technologies that are precise, gentle on materials and at the same time low-emission - combined with automated process control and intelligent energy management.
Comparison of welding processes
Submerged arc welding and co. - welding processes and their energy consumption at a glance
Each welding process consumes different amounts of energy. These are the most common processes:
- TIG welding: Suitable for demanding materials such as aluminum or stainless steel. Offers maximum precision, but also comparatively high energy and gas consumption.
- MAG/MIG welding: Economical and fast, especially in combination with pulsed arc technology. High degree of automation possible.
- Submerged arc welding: Particularly energy-saving and efficient with thick materials and for serial applications with consistent geometry.
- Laser welding and electron beam welding: working with concentrated energy density for high welding speed and minimal heat input. Ideal for high-precision components.
- Cold Metal Transfer (CMT): Revolutionary process with very low heat input and excellent gap bridging.
The most energy-efficient processes are characterized by controlled heat input, low material distortion and minimal post-processing - all of which determine the sustainability of the welding processes.
Factors influencing energy efficiency
Process parameters as a lever for efficiency
Energy-saving welding is particularly about the relevant process parameters. These include
- Current and voltage
- Wire feed speed
- Gas flow rate
- Welding speed
- Duty cycle (duty cycle)
Even the slightest deviation from the optimum settings can significantly increase power consumption. At Schnelldorfer Maschinenbau, you will therefore find modern welding systems on which you can set all the important parameters precisely and adjust them yourself during operation - for less energy loss and errors in the welding process.
Protective gases: Effective, but energy-intensive
Shielding gases such as argon, helium or mixed gases are part of many welding processes. The problem is that they are a relevant energy and cost factor, as the extraction, storage and dosing of these gases alone involves considerable effort. To reduce this, you should
- Use process with less gas,
- Use gas-optimized burner nozzles,
- apply precise flow controls and
- adapt the gas type perfectly to the respective process and material.
In addition, it is advisable to simply check whether more cost-effective alternatives such as nitrogen-argon mixtures are possible for certain applications.
Schnelldorfer Maschinenbau: Energy-efficient welding technology with a system
Automated welding systems have become an integral part of modern production processes. They keep the welding quality consistently high and the process parameters exactly the same - and thus create a significantly better energy balance. At Schnelldorfer Maschinenbau, we therefore use digital control systems with intuitive user interfaces and networked sensors that pave the way for the following:
- Real-time monitoring of energy consumption
- Automatic adjustment of the welding power
- Early error detection and avoidance
- Documented process reliability for quality assurance
The good thing about this is that the clever combination of automation and digitalization not only saves electricity costs and resources, but also shortens production times and significantly reduces reject rates. All in all, this results in significantly more economical and, above all, more sustainable welding processes - and these are guaranteed to meet the increasing demands on quality and environmental compatibility.

Frequently asked questions (FAQ)
Which welding processes are considered particularly energy-efficient?
The most energy-efficient processes include cold metal transfer (CMT), laser welding and electron beam welding. They work with a low heat input, precise energy distribution and also reduce material distortion - ideal for energy-saving processes.
How can I save energy and resources when welding?
Use modern, digitally controlled welding systems, optimize process parameters such as amperage, gas flow and wire feed, and select processes with reduced shielding gas consumption. All of this saves energy and therefore protects the environment and your wallet.
Why is energy efficiency so important in welding technology?
Energy-efficient welding is important because it reduces electricity costs and resource consumption on the one hand, and significantly lowers the sustainability footprint of production on the other. This is a clear advantage when you consider the rising energy costs and increasing environmental requirements.
