Question asked is for an aplication of a cookin PAN Fabricated out of 304 Stainless Steel sheet 2 to 3 mm thick sheet material. To improve Thermal conduction it is desired to weld the bottom of the cooking PAN with 10 to 12 mm thick Mild Steel plate material. Operating Temperature may be in the region of 700 to 800 Degree Centigrade as the bottom of PAN is directly heated with gas fired burners. Please give valuable input for this application. THANKS.

Why would you do this since you can buy stainless steel clad plate in various thicknesses right from the mill, and all you have to do is form it.
The stainless steel is clad directly to the steel plate by a heat and pressure rolling process.
We built a lot of chemical equipment using stainless steel clad plate, such as tanks, mixing vats, pressure vessels, etc,

#Welding Mild Steel to Stainless Steel:
Mixed-metal welding can be satisfactory, generally using an over-alloyed welding consumable such as Grade 309L, but caution must be exercised to prevent carbon migration into the part of the stainless steel exposed to the corrosive environment. Differential expansion rates can also lead to excessive stresses, particularly at tack welds. Stainless steel attachment pads between a stainless steel vessel and its mild steel support can assist in reducing these problems.
