Aluminothermic Welding Kits

Aluminothermic Welding Kits Components

Thermit Kits

Iron III DE / QU Series, premixed, pre-measured packets

Disposable Crucible

Reaction chamber; molten steel is automatically poured out after the reaction is complete

Crucible Cover

High-temperature-resistant ceramic material with side handles

crucible bracket

Crucible Bracket

Blue metal bracket that securely supports the crucible

High-Temperature Matches

Specialized ignition matches for safe and reliable ignition of the flux

Preheater + Rack + Nozzle

Comes with a long-shank nozzle and mounting base; rail-end preheating

Propane Pressure Reducer

Dual-dial pressure gauge, brass valve body

Oxygen Flow Meter

Glass-tube float flowmeter with red hose

Welding Sand Frame

Quartz sand withstands temperatures up to 2,500°C; multi-piece metal/sand mold assembly with an iron shell to prevent moisture ingress

Sealing/Luting Sand & Disc Gate

Sealing sand to prevent molten steel leakage; use the Disc Gate to seal the bottom of the crucible until the reaction is complete.

Rail Cutter

Orange body, gasoline-powered

Rail Grinder

Red frame, electric/internal combustion engine, ground after welding

Slag Removal Stick

High-temperature-resistant material; remove weld slag after welding

Rail Alignment Device

A multi-bolt adjustment mechanism ensures that the rail ends are aligned

Bow Card

White metal frame, aligned with and secured to the rail

Slag Receiving Hopper

White, high-temperature-resistant material with a long handle; used for removing slag after welding

Timing Stopwatch

Precise Control of Preheating Time and Reaction Cycle
