Resistance Seam Welding
Resistance Seam Welding
Lynn Welding provides Nadcap accredited resistance seam welding services to its national and international customers.
Resistance seam welding: Lynn Welding provides resistance seam 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 seam 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 Seam Welding: Resistance welding consists of the joining of two or more pieces of metal by the application of heat, electricity, and pressure. Resistance seam 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.
Resistance Seam welding is one of the resistance welding services we are experienced with.
Resistance Seam Welding: is the process of making a series of overlapping welds by using two rotating wheel electrodes without opening the electrodes between spots. This type of weld is air and liquid tight. Our NADCAP certification also allows us to perform this type of welding procedure for the aerospace and defense industries. Stitch
Special considerations when resistance spot welding aerospace grade aluminum.
Feb 12, 2020
As a material, Aluminum requires extra attention when welding. Defects such as porosity, cracking, and voids can occur more frequently compared to other metals. Lynn Welding is especially good at giving aluminum the attention it deserves; whether it’s 2-ply, 3-ply, or even welding through sealant.

Good afternoon, just wanted to let you know that the remainder of the heat shields should arrive today or tomorrow. Send regular ground, there is no emergency on these. We put that fire out and they were very happy with the product and the circus act that we performed to make it happen. I really appreciate all your help with all the projects that we have worked on together.”
