It is obvious from the growing consumption of metals, increasing need of transport and energy, that more joining and welding will be needed. This is accompanied by what is so called 'the globalization'. China, for example is nowadays by far the largest consumer of steels with about 27% of the world's production - with a high annual growth exceeding 25 %. The consumption of Al has raised lower than expected, but it may increase rapidly when more Al is used in the production of cars. As welding is closely allied to the consumption of metals, the present paper outlines the future of welding and joining with view on material and industry sectors (automotive industry, shipbuilding, power generation, transport). This include sustainable environment demands development of the joining processes and safety issues that will require major developments in welding processes, for example the increase of productivity in Tandem MIG/MAG welding and Submerged Arc Welding with a synergetic cold wire technique. New joining processes introduced in the paper include Laser Hybrid Welding, some new variants of Friction Stir Welding, as well as arc and laser brazing. It is expected that structural adhesives will grow but from a low level. The limited design knowledge, lifetime of the joint and working environment concerns are major hurdles for rapid growth. Mechanical joining, such as clinching and selfpiercing riveting, will also continue to grow. The main driving forces in the joining processes are shipbuilding and construction, car manufacturing and sustainability.
