Copper Chill Blocks - High-Performance Heat Control for Precision V-band Flange Welding
Our Copper Chill Blocks are engineered to solve one of the most common problems in precision welding: uncontrolled heat buildup. Manufactured from a high-tech Tellurium Copper alloy, these chill blocks offer exceptional durability, oxidation resistance, and thermal performance in demanding production welding environments.
Designed to withstand extreme welding heat, the Copper Chill Blocks rapidly pull heat away from the flange or weld zone, preventing warpage, distortion, and overheating of precision-machined components. By efficiently transferring heat out of the part, they help maintain flatness, dimensional accuracy, and consistent weld quality, especially when working with titanium or stainless steel.
Tellurium Copper delivers a major performance advantage over aluminum alternatives, providing approximately 40% higher thermal and electrical conductivity. In addition, copper’s significantly greater mass plays a critical role in heat control. These chill blocks are approximately 70% heavier than an equivalent aluminum part, allowing them to act as a true heat sink while also offering stable, hands-free positioning during weld setup.
The hex-shaped heat dissipation fins increase surface area, promoting faster heat transfer and quicker cooldown times an essential benefit in production welding environments where repeatability and cycle time matter.
Beyond heat management, each Copper Chill Block is designed as a complete purge and fit-up solution. A multi-layer stainless steel diffuser is integrated to eliminate turbulence inside the tube or pipe while maximizing argon efficiency. Our Multi-layer Stainless Mesh diffuser promotes laminar purge gas flow, improving internal weld quality and reducing argon consumption.
Multiple argon inlet ports allow purge gas to be introduced from either the bottom or the side of the chill block, giving fabricators flexibility in setup while working with gravity to properly displace oxygen. This design supports consistent, contamination-free purge environments for critical weldments.
To complete the system, each chill block includes a high-performance quick-release fabrication fit-up clamp, ensuring secure positioning and fast part changes without compromising alignment.
