“…Za ovaj termin, a ovde se radi se o lemljenu primenom MIG i TIG postupaka [11,12], zakoje se u anglosaksonskoj literaturi koriste dve reči braze welding, označavajući da se radi prvo o lemljenju a onda o zavarivanju, a na srpski se može adekvatno prevesti kao lemljenje zavarivanjem, a ne bi bila greška ako se nazove i zavarivačko lemljenje. Podsećanja radi, kao kriterijum za razvrstavanje na postupke zavarivanja i lemljenja su temperature topljenja, sl.…”

Improvements in brazing technologies are not widely present as in welding technologies. Many artefacts from the encient times show that brazing technologies are in use over 5000 years, what make them older from welding procedures. A long time the brazing was applied on the king courts for making jewels and/or ornamental pieces. For a particular technologies from that time hardly to be said that they are "primitive", because they are founded in application (as we today use to say diffusion welding/brazing procedure), which are nowdays are in use in changed form (by application of a pressure) in production of reliable components from airor cosmic industry. The application of MIG method is known and widely used in welding procedures, almost for steels (both for common structural or stainless) also in numerous non-ferrous metals (aluminium, copper, titanium, etc.), but this method markably less is used for brazing. Here will be shown couple of examples of MIG brazing of some complex structural shapes.

The brazing of steel and aluminium alloy using low melting point aluminium based fillers has been extensively studied and the technique has been used in many industries, especially the automotive industry. The strength and failure mode of AR500 steel and AA7075 aluminium alloy brazing joint using the Al-Si-Zn filler metal will be measured and calculated in this paper. However, the adverse effect of intermetallic phases formation on the joint strength has limited the application of this joining method.These dissimilar metals possessing a high strength joint would be of benefit to industry especially in reducing the weight of products. The torch brazing method using Al-Si-Zn base filler metal wasused to join AR500 steel and AA7075 aluminium alloy in this study. The intermetallic phase formation of the brazing on was investigated by scanning electron microscopy and the mechanical strength of the joints was evaluated by shear testing, flexural testing and low velocity impact testing. A maximum shear load of 6460 N was obtained. The presence of intermetallic phases was found to have some effect on the strength of the brazed joint. However, overall, this brazing process using Al-Si-Zn filler metal facilitates the joining of these dissimilar metals to improve the mechanical properties of the joint
