China Graphite Mould for Exothermic Weld, Find details about China Graphite, Pyrolytic Graphite Sheet/Plate from Graphite Mould for Exothermic Weld
Step 1 | Locate the conductors (A) to be joined in the weld cavity (B) and close the mould (C). |
Step 2 | Locate the steel retaining disc in the base of the crucible (D). Pour in the weld powder (E) followed by the starting powder (F). Ignite starting powder with a spark gun. |
Step 3 | The resulting exothermic reaction reduces the weld powder to molten copper alloy which melts the retaining disc and flows into the weld cavity where it partially melts the conductors (G). |
Step 4 | The molten copper alloy cools to leave a fusion weld of great mechanical and electrical integrity. |
