Welding Transportation’s Future

Welding Transportation’s Future

Welding: from stacking beads, stinging from the buzz box, and torching up some welding gas, we have our lingo. What separates us welders from the brazers and solderers of the world is the high heat it takes to get our metals joined. That allows welders to join metals of different natures together, letting our skill combine the materials needed to built our infrastructure with the right welding equipment.


China’s high speed rail is the longest in the world. While America has focused on building its automotive industry other countries have prioritized more centralized modes of transit. Both of these locomotive methods requires lots of metal. In fact each industry requires highly trained professional welders to get the job done. Can you picture the USA transitioning from one auto per person to thirty people per one train car? It would take a lot of infrastructure and planning, with cooperation between cities, states, and federal government.


Did you know that one of the largest broad-scale uses of welding operates on train tracks? The track welder allows those in the maintenance and repair industries to undertake precision welds on the fly, so to speak. Train tracks themselves require heavy weldments to keep the steel rails joined together under the tremendous pressure of passing train cars. This specific kind of welding is called thermite welding. This welding process bears some similarity to its ancient cousin the blacksmith’s forge, with some modern adjustment. Good old crucibles are a piece of welding equipment you don’t often find in the modern welding shop, but for rail welding the job requires different tools on different terrain.
