OVERVIEW

Arcair 3/4" x 12" x 6" Carbon Plate: Versatile Weld Support

Maximize your fabrication efficiency with the Arcair 48123006 Carbon Plate. This substantial slab of high-purity carbon graphite measures 3/4 inches in thickness, providing a robust solution for a variety of welding challenges. While Arcair is famous for their gouging rods, their carbon plates are an unsung hero in the shop, offering indispensable utility for welders who need to control heat and weld geometry precisely.

This plate is an essential tool for backing welds. When you are dealing with poor fit-up or require a smooth root pass on materials where a permanent backing bar isn't an option, this carbon plate saves the day. It supports the molten metal, allowing you to weld with confidence, and because steel and aluminum do not bond to carbon, the plate removes easily after the job is done. This leaves a clean, professional finish on the backside of the weld, reducing the need for extensive post-weld grinding or back-gouging.

Durability and machinability are standout features of this product. The 3/4-inch thickness ensures the plate won't crack easily under thermal stress, making it reusable for multiple applications. If you have a unique joint configuration, you can cut or sand this plate to fit tight corners or irregular shapes. It is also widely used as a heat sink (chill block) to prevent distortion in thin sheet metal or to protect rubber seals, glass, and paint near the weld zone. Add the Arcair 48123006 to your arsenal and experience the difference that professional-grade thermal management tools make in your daily operations.

Features & Benefits

  • Non-Fusing: Weld metal does not stick to the carbon, ensuring easy removal.
  • Customizable: Soft enough to be cut or shaped with standard shop tools for custom fit-ups.
  • High Heat Resistance: Withstands the intense heat of the welding arc without melting.
  • Reusable: Durable construction allows for repeated use in many backing and heat sink applications.

FAQ

It is primarily used as a weld backing material to support the molten puddle and prevent burn-through, or as a heat sink to dissipate heat from the workpiece.

Yes, carbon graphite is relatively soft and can be easily cut, sawed, or sanded to fit specific joint configurations or shapes.

No, standard weld metals like steel and aluminum do not fuse to carbon, allowing the plate to be easily removed after welding.

Yes, carbon graphite is electrically conductive. Care should be taken to ensure it does not inadvertently complete a circuit where not intended, although this property is useful for certain arc applications.

This plate measures 3/4 inch in thickness, 12 inches in length, and 6 inches in width.

While made of similar material to gouging rods, this large plate is not designed for a standard gouging torch. It is intended for backing, damming, and heat control.

This item is sold as a single unit (1 per each).

Yes, when clamped near the weld zone, the carbon plate acts as a chill block (heat sink), absorbing heat and helping to minimize warping and distortion in the base metal.
