Technological solutions in inspecting and quality control of Aluminothermic welding, Flash butt welding, and other structures at urban railway projects in Vietnam
Abstract
Railway, or rail transport is a means of transportation, a factor of economic development, used for the transportation of goods as well as passengers. The transportation system which uses tracks and metal wheels (usually made of steel) mounted on the tracks, such as locomotives and carriages (This system is called a train). Rail transport has existed for a long time and is considered an important means of transport worldwide. Rail transport is also the fastest means of transport, reducing traffic congestion and environmental pollution. The railway system connects regions, economic impulse, trade, and tourism.
The design, construction, quality assurance, and safety are extremely important factors to prevent incidents and disruptions during long-term operations. Therefore, quality control through the testing during the building operations of structural components as role very important. In this article, we present some testing methods for the quality control of Aluminothermic welding, as well as other tests in the railway project. The article discusses the principles, advantages, limitations, and actual application of these techniques.
