2. Metal fume fever - Wikipedia

   en.wikipedia.org/wiki/Metal_fume_fever

   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 ...

3. Weld purging - Wikipedia

   en.wikipedia.org/wiki/Weld_purging

   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 ...

4. Intergranular corrosion - Wikipedia

   en.wikipedia.org/wiki/Intergranular_corrosion

   Stainless steels can be stabilized against this behavior by addition of titanium, niobium, or tantalum, which form titanium carbide, niobium carbide and tantalum carbide preferentially to chromium carbide, by lowering the content of carbon in the steel and in case of welding also in the filler metal under 0.02%, or by heating the entire part ...

5. Welding defect - Wikipedia

   en.wikipedia.org/wiki/Welding_defect

   Therefore, the use of austenitic stainless steel or nickel-base filler could be considered due to its ductile nature. Also, post weld heat treatment (PWHT) will release any residual stresses on the weld joint. Hardness of weld metal and heat affected zone (HAZ): Hardness is correlated with the brittleness of the material.

6. Crevice corrosion - Wikipedia

   en.wikipedia.org/wiki/Crevice_corrosion

   In general, crevice corrosion is of greatest concern for materials which are normally passive metals, like stainless steel or aluminum. Crevice corrosion tends to be of greatest significance to components built of highly corrosion-resistant superalloys and operating with the purest -available water chemistry.

7. Rotary friction welding - Wikipedia

   en.wikipedia.org/wiki/Rotary_friction_welding

   The AISI 304 stainless steel has higher strength than the aluminum alloy. Hence, the formation of flashes was restricted to AA1050 aluminum only. [49] Rods Aluminium AA1050 and AISI 304 Stainless steel afret tensile test. [49] On this photo rupture occurring on aluminium site away from the bonding interface. Tungsten - steel weld. [50]

8. Welding - Wikipedia

   en.wikipedia.org/wiki/Welding

   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. [50]

9. Flux (metallurgy) - Wikipedia

   en.wikipedia.org/wiki/Flux_(metallurgy)

   Stainless steel is a material which is difficult to solder because of its stable, self-healing surface oxide layer and its low thermal conductivity. A solution of zinc chloride in hydrochloric acid is a common flux for stainless steels; it has however to be thoroughly removed afterwards as it would cause pitting corrosion. Another highly ...
