description

This seminar covers all commonly used rail-welding procedures. Welding procedures and consumables, as well as grinding of welds will be discussed in detail. The metallurgy of rails, the basis of rail welding, will be presented in a simple way.

topics

•  Metallurgy of rails and the impact of rail metallurgy on rail welding - Why do have rails the chemical composition as they have?
• Chemical composition of rails, rail geometry and the impact of both on welding technology            
• Flash butt welding – stationary and mobile machines - process description and assessment of welding programs          
• Aluminothermic welding of Vignol and grooved rails - process and critical factors for a successful weld
• Innershield and stick welding of Vignol and grooved rails
• Choice of welding consumables
• Grinding of welds – the most important process step at rail welding
• Weld failures and how to avoid them
• Best practise
