| Abstract: | Broken metal is a constant problem in field of conservation. The preferred method of rejoining parts is bonding, but this is not always applicable. The question was to what extent brazing, arc welding and laser welding can be used for such problems. To answer this question, the processes were explained in theory and tested in practice using test strips. Test strips of new and historic brass, iron and silver were broken and joined using the techniques. All three techniques were able to successfully rejoin the individual parts. Laser beam welding appears to be the best option and can be used everywhere. Arc welding is also excellent. Soldering is only applicable to specific objects and for certain problems. The soldering process negatively alters the surface of the metals. Neither arc welding nor laser welding caused any negative changes to the surface. |
