Exothermic welding... #USBRL ... #Adventuresyatra

Exothermic welding is a simple, economical method of making permanent, very high quality electrical earthing connections – the exothermic welding/Joint process uses the high temperature reaction of copper oxide and aluminium within a semi-permanent graphite mould to form electrical connections mainly between copper to copper or copper to steel.
It only requires a mould, weld powder, handle clamp and exothermic welding tools.
