Conventional welding process

Description and corrosion resistance. Nitronic 50 stainless steel provides a combination of corrosion resistance and strength not formd in any other commercial material available in its price range. This austenitic stainless has corrosion resistance greater than that provided by S31600, plus approximately twice the yield strength at room temperature. In addition to the improved corrosion resistance, Nitronic 50 can he welded successfully using conventional welding processes that are normally employed with the austenitic stainless steels. 

Sometimes conventional welding or a mechanical joining process is just not possible. Substrate materials may be incompatible for metallurgical welding due to their thermal expansion coefficients, chemistry, or heat resistance. The end product may not be able to accept the bulk or shape required by mechanical fasteners. 

Several methods of generating heat can be used in welding processes. In conventional heat-welding processes, the heat is applied to a fabric substrate through conduction, and the surface of the fabric is melted in the process. Advanced welding processes are those where the heating source is not in direct contact with the substrate. 

The laser beam offers the advantage of precise machining, even in places or on materials that cannot be processed with the conventional welding methods. 

Nitronic 60 is also readily welded using conventional joining processes. It can be handled similarly to S30400 and S31600 steels. No preheat or post weld heat treatments are necessary, other than the normal stress relief used in heavy fabrication. Most applications use Nitronic 60 in the as-welded condition, unless corrosion resistance is a consideration. PiUerless fusion welds (autogenous) have been made using GTA. These... 

Short glass fibers are commonly added to polymers to enhance their properties. When joining these materials, it is desirable to maintain the enhanced characteristics of the bulk material at the weld interface by orienting the fibers perpendicular to, and across the joint. However, in most conventional plastics welding processes, such as hot plate welding, the glass fibers tend to orient themselves parallel to the weld joint.
