Weld purging is the act of removing, from the vicinity of the joint; oxygen, water vapour and any other gases or vapours that might oxidize or contaminate a welding joint as it is being welded and immediately after welding. [1] Stainless steels, duplex steels, titanium-, nickel- and zirconium- alloys are sensitive to the presence of air, oxygen ...
Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an iron-based alloy containing a minimum level of chromium that is resistant to rusting and corrosion. Stainless steel's resistance to corrosion results from the 10.5%, or more, chromium content which forms a passive film that can protect the material ...

The energy from the impact plasticizes the materials, forming a weld, even though only a limited amount of heat is generated. The process is commonly used for welding dissimilar materials, including bonding aluminum to carbon steel in ship hulls and stainless steel or titanium to carbon steel in petrochemical pressure vessels.

Metal fume fever, also known as brass founders' ague, brass shakes, [1] zinc shakes, galvie flu, galvo poisoning, metal dust fever, welding shivers, or Monday morning fever, [2] is an illness primarily caused by exposure to chemicals such as zinc oxide (ZnO), aluminium oxide (Al 2 O 3), or magnesium oxide (MgO) which are produced as byproducts in the fumes that result when certain metals are ...
A steel circular brush is attached to an angle grinder and used to remove the first layer leaving behind a bumpy surface similar to hammered bronze. In the glass industry for "fire polishing". In jewelry production for "water welding" using a water torch (an oxyhydrogen torch whose gas supply is generated immediately by electrolysis of water).
