Feb 21 2016 nbsp 0183 32 Stainless steel is defined as a steel alloy with a minimum of 10 5 chromium by mass Like steel stainless steel comes in a variety of forms that can be made by altering its microstructure and then be further altered by changing the alloy s chemical makeup i e adding or removing its elements We understand that welding equipment is of no use unless we also provide the welding materials consumables to go with it With this in mind we offer an extensive range of mig wire tig rods electrodes and gas welding amp brazing rods for steel stainless steel cast iron bronze aluminium hardfacing and many other welding materials for the more sophisticated alloys Welding electrode selection Chart for Carbon steel to stainless steel All Stainless Steel The below chart gives very detailed guidelines for the stick welding SMAW or equivalent TIG MIG filler wires for different types of stainless steel welding In these consumables XX means 15 16 or 17 type For example E309L XX you can use either 75 Nickel Iron Welding Rod for Malleable Ductile and Nodular Cast Irons 65 00 – 650 00 Aluminum welding brazing and soldering with Muggy Weld alloys SSF 6 Stainless Steel Solder Rod Brazes Copper to Stainless Steel Tubing Reference is often made to stainless steel in the singular sense as if it were one material Actually there are over 50 stainless steel alloys Three general classifications are used to identify stainless steels They are 1 Metallurgical Structure 2 The AISI numbering system namely 200 300 and 400 Series numbers 3

Jan 25 2022 nbsp 0183 32 The high temperature deformation behavior of metals and alloys undergoes complex mechanisms depending on the deformation conditions The microstructure and mechanical properties after deformation are important factors that determine the strength and durability of the final product Therefore many studies to predict the microstructure and Mar 07 2006 nbsp 0183 32 Guidelines for tungsten electrodes Identifying selecting and preparing tungsten electrodes it is best used to weld carbon steel stainless steel nickel alloys and titanium and in some cases it can replace 2 percent thoriated electrodes which is an advantage for welding steel and stainless steel on DC or AC from square wave power What is stainless steel Stainless steels as their name suggests are a group of steel alloys with a shiny appearance and good corrosion resistance The base element 70 80 is Iron Fe with a minimum of 10 5 Chromium most grades will have additional alloying elements such as nickel Ni and molybdenum Mo a wide range of both solid carbon steel and tubular metal cored electrodes The alloy material range for GMAW includes carbon steel stainless steel aluminum magnesium copper nickel silicon bronze and tubular metal cored surfacing alloys The GMAW process lends itself to semiautomatic robotic automation and hard automation welding The pipe interior should be purged with argon using the standard practices for other alloys such as stainless steel and nickel alloys The manual root pass procedures for Cu Ni are basically the same as for other alloy piping but the welders may notice the weld metal does not flow as well as an austinetic stainless steel
