Exothermic Welding with Apliweld Secure+

Exothermic Welding with Apliweld Secure+

What is Exothermic Welding?

Exothermic Welding with Apliweld Secure+Exothermic welding, also know as exothermic binding, thermite welding and thermite welding, is a welding process that achieves the molecular binding of two or more metallic conductors by a chemical reaction.

This molecular binding improves mechanical, electrical and anti-corrosion properties compared with any mechanical or clamped connection.

Apliweld® exothermic welding is the simplest, safest and most efficient way to make permanent, reliable, high conductivity and high quality electrical earthing connections.

Operating Procedure

The operating procedure is very similar whether you are making a connection using a specific or a multiple mould.

Exothermic Welding procedure step 1 STEP 1:
Clean and remove any impurities from the conductors and the mould.

Recommended use of Conductor Cleaning Brush (AT-061N) and Vertical Mould Cleaning Brush (AT-062N).

Apliweld Exothermic Welding Operating Procedure Step 2 STEP 2:
Ensure mould is dry, by pre-heating it or making a test joint.

Recommended use of Blow Torch (AT-075N) and Gas Cartridge (AT-076N).

Apliweld Exothermic Welding Operating Procedure Step 3 STEP 3:
Place the conductors in the mould and close the mould. Make sure it is perfectly closed.

When using a multiple mould, add layers of Cavity Sealants (MM-CS) between conductors, for a perfect result.

Apliweld Exothermic Welding Operating Procedure Step 4 STEP 4:
Insert the necessary number of Apliweld-T Exothermic Welding Compound Tablets (AT-020N or AT-021N).

See engraved mould surface or consult the appropriate Selection Guide:Multiple Mould Selection Guide  Specific Mould Selection Guide

 

Apliweld Exothermic Welding Operating Procedure Step 5 STEP 5:
Insert and connect the Apliweld-E Exothermic Welding Electronic Starter (AT-010N).
Apliweld Exothermic Welding Operating Procedure Step 6 STEP 6:
Connect the Electronic Ignition Device/ Box (AT-114N) with the mould using the Connection Cables (AT-098N).
Apliweld Exothermic Welding Operating Procedure Step 7 STEP 7:
Obtain the welding. Ensure that you wait some time before opening the mould to allow joint to solidify.
Apliweld Exothermic Welding Operating Procedure Step 8 STEP 8:
Result: Perfect connection!
