Hydraulic Flash Butt Welder

• 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; little or no end preparation; high accuracy of welding joints; high consistency of weld parameters.
• Fully hydraulically operated; forced air cooled transformer having core of high grade silicon steel confirms to IS 4804, part II; precision control on initial die opening.
• Flash off length, time, length and final die opening; precision time delay circuit for upset current.
• Safety and sequential interlinks provided for prolonged trouble free tooling operation; pre-heat and post heat cycles available as required.
