Flash Butt Welder 
Flash Butt WelderFeatures
INTRODUCTION
Flash Butt Welding is a modern technique of joining mild steel, alloy steel and other dissimilar metals in various tubular or solid sections. Weld quality obtained is mechanically or metallurgically similar to the parent metal. Because of shorter weld times the process is suited for higher production than other conventional methods. No additional items such as rods or gas etc. are required thus it is highly economical. Other features include (a) little or no end preparation (b) High accuracy of welding joints (c) High consistency of weld parameters.
Applications
Welding of HSS to EN9 tools, tubular parts, bicycle and moped wheel rims, starter ring gears, window sections, table knives, construction steel bars upto 30 dia., bottom rings of cylinders, continuous coil strips.
