- copper pipe
- parts from brass bar
- metal cutting
- cold plastic deformation
- manual brazing – special process that uses local heating technology of the two areas (parts) that must be welded (glued) and adding a different bonding material for bonding copper-copper / copper-brass or copper-steel.
- leak detection control – the quality of brazing welding is that because of the adhesion of the bonding material it can provide resistance to pressure test, especially as in case of the air-conditioning pipes that require values of up to 42 bar.
