Resistance Welding at Lynn Welding

Lynn Welding provides resistance spot welding and resistance seam welding services to numerous customers. The team utilizes SCIAKY welders, renowned for maintaining the strictest tolerances required by the aerospace industry. These SCIAKY welders are capable of welding aluminum, stainless steel, titanium, Inconel, and most other metals while ensuring the proper conditions for a quality weld. The internal quality department closely monitors the resistance welding operations to ensure compliance with the guidelines established by NADCAP (National Aerospace and Defense Contractors Accreditation Program).

Resistance welding is a process that joins two or more pieces of metal through the application of heat, electricity, and pressure. In this method, the welding heat is generated by the resistance of the parts being welded and the passage of an electric current. Unlike other welding forms, resistance welding does not use extraneous materials such as fluxes or filler rods, thus avoiding complications in the weld's metallography. Additionally, resistance welding differs from fusion welding by applying mechanical pressure to forge the heated parts together. This pressure refines the grain structure, often resulting in a weld with physical properties equal to or sometimes superior to the parent material.

TOUCH

Spot Welding

The most widely used form of resistance welding is performed with electrodes that remain essentially stationary during the welding process. Lynn Welding is NADCAP-accredited for the resistance spot welding procedure.

Spot Welding

TOUCH

Stitch Welding

This process involves using the spot weld configuration but overlapping the actual weld nuggets along the length of the two pieces of metal being joined. This method can achieve the results of a seam weld in areas where two rotating wheel electrodes cannot fit.

TOUCH

Seam Welding

This process involves creating a series of overlapping air- and liquid-tight welds using two rotating wheel electrodes without separating the electrodes between spots. Lynn Welding's NADCAP certification also authorizes the performance of this procedure for the aerospace and defense industries.
