Resistance Spot Welding
Lynn Welding is Nadcap Accredited for Resistance Spot Welding Per AWS D17.2
Lynn Welding provides Nadcap accredited resistance welding services to its national and international customers.
Resistance spot welding: Lynn Welding provides resistance spot welding services to many of its customers. Lynn Welding 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).
What is Resistance Welding: Resistance welding consists of the joining of two or more pieces of metal by the application of heat, electricity and pressure. Resistance welding embraces that branch of welding art in which the welding heat in the parts to be welded is generated by the resistance offered by these parts to 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.
Common Material Types for Resistance Welding Processes
- Aluminum Resistance Spot Welding
- Stainless Steel Resistance Spot Welding
- Titanium Resistance Spot Welding
- Inconel Resistance Spot Welding
- and most other metals
Resistance Spot Welding is one of 4 main types of resistance welding we offer
Spot welding is the most widely used form of resistance welding. This type of welding is done with electrodes which are held essentially stationary while the weld is being made. We are NADCAP accredited for this welding procedure.
