Eco-Friendly Welding Practices You Should Be Aware Of

eco-friendly weldingWelding is an important part of the industrial world. It is a technique used by big, fully-automated factories and individuals alike. In fact, for many people, welding is an art and a serious hobby to get into. It is a useful skill to have for those who love DIY projects and creating things.

Over the years, the world is becoming more serious about protecting the environment; the welding industry is no different. The ongoing push for clean production methods is affecting welding as well, which is why there are now several eco-welding practices you should be aware of.

Diffusive Welding

Diffusive welding is currently one of the most-used welding techniques for its ability to create perfect, strong joints. Diffusive welding is also preferred for its efficiency, plus it is a welding method that scales well. When you combine the cost-effectiveness and speed of diffusive welding, it is easy to see why the method is very popular for small to medium productions.

Of course, there is also the eco-friendly side of diffusive welding. The technique eliminates the need for flux. Since the process no longer uses carbonate and silicate materials, there are no outgasses and the entire process is safer to the environment.

Instead of using flux, diffusive welding combines pressure and heat to create perfect joints with an incredible consistency. The combination also prevents atmospheric gasses from reaching the bonded surface, minimizing the risk of oxidation along the way. There is almost no change to the welded material, so it is possible to achieve a very clean weld or look with diffusive welding.

Vacuum Soldering

Similar to other types of welding, traditional soldering requires the use of flux. When heated to a certain temperature, flux releases gas to push out atmospheric gasses and prevent them from reaching the parent material. Flux needs to be cleaned, too, and the cleaning agents used in the process aren’t always safe for the environment.

Vacuum soldering transforms the process by using hydrogen instead of flux. As the name suggests, hydrogen is applied to the soldering process in a vacuum. This, in turn, creates the same stability that flux offers, all without harmful materials being produced in the process. Based on this comparison of welding equipment, vacuum soldering gear is becoming more popular.

Reclaiming Scraps

The best and simplest way to reduce your waste as a welder, however, is by reclaiming the scraps you amass from a project and using them in another. Recycling scrap materials is a great way to make welding friendlier to the environment. Even big companies and welders are starting to do more recycling.

You can go a step further and plan for minimum scrap. Instead of trying several times to make a joint and wasting previous material, for instance, you can plan the weld more carefully and get it right on the first pass. It is a simple thing to do, but it has a big impact nonetheless. Combined with the welding techniques we covered earlier, making welding eco-friendly is an easy task to accomplish.
