Resistance welding is a form of marrying of metals through the application of pressure and passing current for a specified interval of time through the metal area. Many design engineers and manufacturers find resistance welding to be advantageous as there is not another form of metal required create the bond other than the base metals. As a result, the effects of resistance welding can be extremely efficient and cost-effective.
There are two Lynn Welding specific resistance welding methods, all suited for specific projects, materials, and joints.
Lynn Welding specializes in spot welding and seam welding. Further, Lynn Welding commonly uses stitch welding. During the stitch welding process, the spot-welding configuration is used but there is an overlap of the weld nuggets over the length of the two different pieces of metal that are being joined. This weld produces the results of a seam weld.
Resistance welding has been popular since the late 19th century, especially with the automobile industry's rise. Resistance welding accounts for approximately 25% of the welding workload. Many welders prefer resistance welding due to the following seven benefits.
Customers typically use resistance welding in the aerospace and automotive industries. Companies such as Bell Helicopter, Collins Aerospace, Kaman Aerospace, Gulfstream, Raytheon, Northrop Grumman, General Dynamics, Rolls-Royce, Beechcraft, GE Aviation, United Launch Alliance, Augusta Westland, Boeing, Sikorsky, and Pratt & Whitney Canada all require resistance welding.
Lynn Welding administers resistance welding duties to many of its customers, using SCIAKY welders, which are regarded as the best in the world. These welders maintain the strictest allowances and tolerances as defined by AWS D17.2 and required by the aerospace industry. Lynn Welding's SCIAKY welders can weld aluminum, titanium, stainless steel, Inconel, and most other metals while maintaining the proper conditions to ensure a quality weld.
Resistance welding operations at Lynn Welding are closely and meticulously monitored by an internal quality department to ensure that all resistance welding functions are within the guidelines set forth by National Aerospace and Defense Contractors Accreditation Program (NADCAP).
