Welding of Stainless Steel. 1. Features of stainless steel. By adding chromium (Cr) to iron (Fe), iron becomes resistant to corrosion in the atmosphere. When the Cr content increases to 1112% or more, the corrosion resistance of steel becomes remarkably high. Hence, the steel with such a high amount of Cr is given a name of stainless steel

Coloring of Stainless Steel GTAW welds

Jul 11, 2008 · Coloring of Stainless Steel GTAW welds. By RonG Date 09-25-2001 20:42. Metals (Steel & SSs) change color with enough heat and when they cool rapidly the color stays near the highest temp that area reached. There is also the fact that many SS are poor conductors of heat which makes the color band travel slower. Considerations for the weldability of types 304L and 316L A calculated Cr eq to Ni eq ratio of 1.52 to 1.9 is recommended to control the primary mode of solidification and prevent solidification cracks in type 304L while the Cr eq /Ni eq ratio of 1.42 to 1.9 is recommended for type 316L stainless steel. A lower limit of 50 ppm sulfur is recommended to avoid possible lack of penetration.

Control of exposure to hexavalent chromium concentration

Background Cr(VI) is a suspected human carcinogen formed as a by-product of stainless steel welding. Nano-alumina and nano-titania coating of electrodes reduced the welding fume levels. Objective To investigate the effect of nano-coating of welding electrodes on Cr(VI) formation rate (Cr(VI) FR) from a shielded metal arc welding process. Corrosion Testing of Weldable 13%Cr Supermartensitic Steel All welding passes were deposited using a 2.4mm Zeron 100X( ) superduplex stainless steel (SDSS) filler wire. After welding, post-weld heat treatment (PWHT) was applied for 5 minutes at 630°C(-0/+20ºC) followed by water cooling, representing industry practice.

The microstructures, phases, residual stresses and retained austenite content of 1Cr5Mo steel welding joint before and after LHT were analyzed with optical microscope Hexavalent chromium in welding fumes - PlymoventJun 04, 2019 · Exposure to hexavalent chromium in welding fumes is primarily associated with welding stainless steel. That doesnt mean it is limited to this material. Usually, chromium is not added to other types of steel, but it can be around at low levels, due to the use of scrap steel in the production process.

    How To:MIG Welding Stainless Steel

    Even though most of the welding machine manufacturers have included a table of materials and voltage settings in the machine, it is highly important for you to pick the right kind of gas and electrode wire to be used for MIG welding stainless steel. Alternative gases that you can use are 98% Argon and 2% Co2 or 98% argon and 2% oxygen mix. Mode of Metal Transfer Laser dissimilar welding of CoCrFeMnNi-high entropy alloy However, we note that most of these studies concentrated on HEA welding, with little focus on dissimilar joining of HEAs and stainless steel or other alloys of equal interest. The only study, to the best of our knowledge, involved joining Al0.1CoCrFeNi-HEA and AISI304 austenitic stainless steel by conventional tungsten inert gas welding [ 20 ].
