Resistance Welding

 Lynn Welding provides resistance spot welding and resistance seam welding services to many of its customers. Our team uses SCIAKY welders which are considered the best in the world for maintaining the strictest tolerances required by the aerospace industry. Our SCIAKY welders are capable of welding aluminum, Stainless steel, Titanium, Inconel and most other metals while maintaining the proper conditions to ensure a quality weld. Our resistance welding operations are closely monitored by our internal quality department which ensures that all of the resistance welding functions fall within the guidelines set forth by NADCAP (National Aerospace and Defense Contractors Accreditation Program).

Resistance welding is the process of joining two or more pieces of metal by the application of heat, electricity, and pressure. Resistance welding embraces the branch of welding art in which the welding heat is generated by the resistance of the parts being welded and the passage of an electric current. It differs from other forms of welding in that no extraneous materials such as fluxes, filler rods, etc. are used; therefore metallography of the weld is not complicated by the addition of these materials. Resistance welding further differs from the fusion welding process, by utilizing the application of mechanical pressure to forge the heated parts together. The effect of the pressure is to refine the grain structure, thus producing a weld with physical properties in most cases equal to the parent material, and sometimes even superior.
