AB  - Making of an artistic piece usually includes a number of different technologies. It implies that for understanding of eventually present irregularities one should knows a lot of technical details. Brazing technology is one of them, inspection of integrity, also. Brazing technology generally has evolved on empirical manner, mainly by trial and error(s). The basic difficulty in this technology is
that the real situation is highly complex due to the presence of large number of variables, some of them may not be easy to recognize. The great problem is the appearance of crack(s) in postcleaning periode, i.e after brazing is finished, it means over years or decades. A good braze joint must be both physically and chemically bounded. One of the available method for investigation is radiographic testing, when the thickness of testing components commonly does not represents a problem. Here provided radiographic testing has
revealed the existence of some indications only at leaves. The indications usualy mean discontinuity in material homogenity. Penetrant testing is a next step for investigation of surface. Registration of indications and their locations are necessary steps in any further approach for removing such discontinuities. Choosing the repair method always is particular problem, however
in entire technique, especially on sensitive artistic component(s). Every action in repairing or restauration may led to more or less visible traces. Unadequate actions may permanently change the appearance or usage of treated artefact. Here is shown one irregularity (crack) at one brazed leaf from an artistic desk lamp.
AB  - Izrada jednog umetničkog dela obično uključuje brojne različite tehnologije. To podrazumeva da je za
razumevanje eventualno prisutnih nepravilnosti potrebno znati puno tehničkih detalja. Tehnologija
lemljenja je jedna od njih, ispitivanje integriteta, takođe. Tehnologija lemljenja, uopšte, se razvijala na
empirijski način, uglavnom pokušajima i greškama. Osnovnu teškoću čini realna situacija, koja je veoma
složena, usled prisustva velikog broja uticajnih veličina, neke od njih se ne mogu lako prepoznati. Veliki
problem je pojava pukotina u periodu posle čišćenja, tj. po završetku lemljenja, a to znači nekada posle
više godina ili decenija. Dobar zalemljeni spoj mora biti valjano fizički i hemijski spojen.
Jedna od primenljivih metoda ispitivanja je radiografsko ispitivanje, kada debljina ispitivanih delova
obično ne predstavlja problem. Ovde izvedena radiografska ispitivanja su nagovestila prisustvo
nekih indikacija samo na listovima. Penetranstsko ispitivanje je sledeći korak za ispitivanje
površine. Registrovanje indikacija i njihovo lociranje su neophodni koraci u svakom daljem
pristupu u cilju uklanjanja takvih diskontinuiteta. Izbor metode reparacije uvek je poseban problem,
dakako u celoj tehnici, a posebno na osetljivim umetničkim predmetima. Svako delovanje u
reparaciji ili restauraciji može dovesti do manje ili više vidljivih tragova. Neodgovarajuća delovanja
mogu dovesti do manje ili više vidljivih tragova. Ovde je pokazana jedna nepravilnost (pukotina)
na zalemljenom listu, na jednoj umetničkoj stonoj lampi.
