Sažetak
To pose a question about future development of e.g. welding means to answer the question of future development of Materials technology. The syntagm Materials technology is a common nominator for Material technology and Production technology. Material technology means the production and application of materials based on discoveries of natural sciences: physics, chemistry and natural technology of the living (biology) and the non-living (other natural sciences). The aim of Material technology is production of substances or materials with the prescribed production and application properties and Production technology making of product with defined geometrical shape and necessary properties during the use of the product. The main question in this discussion is whether we can predict the future of Materials technology. We assume that the answer is positive, based on two analyses, fractal past and the future of general technology and systemic analysis. We use a brief fractal history of general technology to predict the future of two human technologies: biotechnology and technology of non-living things. From the description of natural and artificial technology we can conclude: even if more parts are made by artificial micro-technological and nano-technological processes (level of atoms), in the very far future the products will be mostly of macro geometrical size. Our prediction is that once developed the production process and product can be only innovative and improved but the development of materials can be a revolutionary one. The revolutionary development of materials means to go to level n-1, the subatomic one. For welding one point from the analysis of general technology is interesting. Natural energy technology started 13.7 billion years ago with electromagnetic radiation. Natural scientists discovered those phenomena around the beginning of 19th century. The necessary equipment which uses this phenomenon, the LASER, was not invented before 1958.
