The welding world is diverse with a range of different skills, techniques and expertise areas. 2 most common materials that every welder works on are Carbon Steel and Stainless Steel. Let us look upon the merits and demerits of each and the procedures. Stainless Steel: Due to the chromium present in stainless steel, they are resistant to rusting. For the same reason, they are widely used in many industries. The welding processes such as Shielded Metal Arc Welding, Gas Tungsten Arc Welding, Flux Cored Arc Welding and Gas Metal Arc Welding can be used upon stainless steel. Both short circuit and spray transfer techniques can be used when following the above mentioned processes. For industrial welds heavier fillers are prefered though for ornamental welds cheaper fillers can be used. Carbon Steel: Carbon steel is classified as either low, medium, high or ultra high based on the amount of carbon used in the alloy. It finds itself some practical applications though it corrodes and rusts easily due to which are protected by coatings and linings. They are easier to weld using MIG and TIG techniques. The preliminary phase is in understanding the position where the 2 materials converge. Knowing the best joining methods for base metals, securing fixtures, choosing the best process for application, wearing the proper protective equipments, understanding the appropriate inert shielding gas and choosing the right filler metal needs to be considered for both the methods.
The processes mentioned above are well trained both theoretically and practically by one of the welding schools providing industry grade tool and die courses in Canada. The details of the course I attended, tool and die from the*_WeldTechTraining Institute_* can be seen here:
