The concepts of "recycling" and "ecology" can also be applied to welding, according to Nikotsu. This approach not only benefits the Earth and the environment but must also provide value to our customers. It is a cost-saving measure. Our company proposes "recycling" through build-up welding. [For example...] ■ By build-up welding parts that were previously replaced and discarded, they can be reused. ■ By extending the lifespan of parts through build-up welding, the replacement cycle is reduced, leading to resource conservation. *For more details, please refer to the PDF materials or feel free to contact us.
