Narrow Gap TIG welding

摘要

The quality and productivity requirements relating to welded joints are inexorably driving industrial companies towards the implementation of automatic processes. These primary objectives are, however, supplemented by more subtle notions such as energy management, bead regularity or even aesthetic criteria for sectors affecting the general public. Several decades of progress in TIG welding have seen it become an essential process that offers not only the widest scope of use but also reasonable operating constraints compared with more recent developments (laser or electron beam welding).
