Innovations in arc welding

摘要

Developments in arc welding processes are strongly related with the need to increase productivity without loosing quality of the welds performed. It is by targeting these aspects that can maintain their competitiveness in the world wide markets. Reduction of costs and competitive pricing are each day more strongly related with technological innovations. MIG/MAG welding is one of the most used processes in industry both in manual and robotized welding. The search for higher productivity and better quality has led to the development of many variants of this process. Conventional TIG is known has a very controllable and precise welding process, to increase conventional TIG deposition rate other TIG variants have been developed in the latest years. The present paper aims at outlining same of the recent innovations in MIG/MAG and TIG welding which represent steps ahead to achieve the objectives outlined above.
