Horizontal Flat Bar End to End Joint – BB7

Product Information:

Horizontal Flat Bar End to End Joint – BB7 is a bar to bar exothermic welded connection that requires a HCD or HCE Handle Clamp.

Features:

The KingsWeld exothermic connection is a permanent,maintenance-free weld that will not loosen overtime or deteriorate with age .There is no increase in resistance in an exothermically weldedconnection, unlike in most pressure type (bolt/crimp) connectionsi.e.copper ground rod or grounding cable attached with ground rod clamps or cable terminal. A kingsWeld weld metal consists of copper oxide, aluminium and flux in a granular (powder) form. Comes in standard sizes.

KingsWeld exothermic mould is manufactured from high quality graphite. This lends itself to easy machining, as well as being able to withstand the high thermal and mechanical shocks produced during the exothermic welding process. Heat obtained in such reactions is in excess of 2000º C.

Our moulds are deisgned to have an average lifetime of 50 to 60 connections. But, if treated with care, it is possible to obtain a significantly longer life.

Graphite is both brittle and soft, therefore it is important that the operator takes care while handling the product. Worn-out or damaged moulds should not be used.

Each mould has a nameplate, detailing the connection type, part code, and the correct weld metal size to be used.

If you do not see the connection, configuration or size of conductor that you require, please contact our sales office who will be pleased to assist you.

More Information:

To make a KingsWeld connection certain items might be required such as a KingsWeld mould, Handle Clamp, Weld Metal, and/or Flint Gun.Mould Care Guide: KingsWeld moulds are manufactured from high quality graphite which, by nature, is soft and needs to be handled with care in order to get the maximum lifetime.

• Always clean the mould after every weld
• Only use KingsWeld cleaning equipment (soft brush) to clean the mould
• Keep the mould dry and away from moisture
• Do not hit or drop the mould
• When not in use, keep the mould in its packaging for protection
• Try not to hit the edges of the mould with the conductors to be connected • Never use a wire brush to clean the mould
• Always use the correct weld metal size, tools and handle clamps

Mould Inspection:

• Handle the mould with care.
• Mould must be dry with fixed lid.
• Identification plate must be attached.
• Mould faces must be smooth,so they seal properly.
• Mould steel disc seat must not show signs of wear, chips or gouges (steel disc must seal the hole properly to prevent weld metal entering the weld cavity prior to welding).
• Tap hole must be well defined.
• Weld cavity must not show signs of wear, chips or gouges (conductors must have a 3mm gap between them prior to welding, fit snugly and not be loose in the mould).
• REGULAR CHECKS HELP KEEP MOULDS IN GOOD CONDITION
