Building Railway Bridges with Construction Welding

All kinds of welding operations are utilized in manufacturing across various industries. When it comes to stud welding, the range of its applications is much broader than you might think. Not only is stud welding used heavily in the production of food-grade appliances, electrical enclosures, connector pins for various applications, sheet metal construction, and much more, it’s also used in the fabrication of critical infrastructure. One common use of stud welding in large-scale construction is bridge building. Many types of bridge construction rely on stud welding for composite structures, fastening systems, and more. At Northland Fastening Systems (NFS), we provide the tools, studs, accessories, and guidance necessary for all applications that depend on construction welding to get the job done correctly.

Not only does stud welding play an important role in roadways and roadway bridges for commercial and consumer travel, it’s also an essential operation for railway bridges. Our nation’s railways—which carry industrial, commercial, and passenger trains all over our country and across our borders—are a highly important part of our economy and our citizenship. Railways support the transport of foods, medicine, water, fuel, and many other products that give communities and businesses access to the necessary items for surviving and thriving.

Construction Welding

Construction welding, and stud welding in particular, are imperative for the composite connection points between slabs of concrete, cement, and other heavy-duty, long-lasting engineering components, and the girders of steel beams that provide flex and strength in an operating bridge.

The combination of concrete slabs and metal beams connected through shear stud beams means railway bridges can meet strict safety standards and hold up to train travel, weather, and the movement of the earth for many years. Shear reinforcement with studs connects two materials securely while also providing ductility and strength in the face of shift and stress.

Railway bridges typically use heeded shear studs with thick diameters, installed in exact row patterns along the seams of concrete slabs. Shear studs used in construction welding for railway and other bridges are typically 125, 150, 175, 200, or 250 mm in height with diameters of 16, 19, 22, or 25 mm.

Shear connector studs are highly economical and robust, creating an engineered structure that reacts to shock flow moving in a predictable pattern across a working railway bridge. For some bridges that utilize metal decking and sheet spans, composite construction with stud welding dramatically increases long-term flexibility, and decreases the effects of brittleness and quickly degrading strength of concrete support systems.
