Introduction

Walter+Bai offers fully automated Charpy impact testing systems for instrumented and non-instrumented testing of metallic standard and sub-size specimens, with or without integrated temperature conditioning.

Our systems combine high-performance pendulum impact testers with intelligent robotic automation to provide reliable, highly reproducible impact testing according to international standards including ISO 148, ASTM E23, ISO 14556 and ASTM E2298. Depending on the application, impact energies from a few Joules up to 900 Joules are available.

Fully Automated Testing

Walter+Bai automated systems are designed for high-throughput laboratories and production environments requiring maximum efficiency and repeatability. The complete testing process can be performed automatically, including:

• Automatic specimen identification
• Barcode reading
• Robotic specimen handling
• Automatic temperature conditioning
• Automatic specimen positioning
• Automatic impact testing
• Automatic data acquisition
• Automatic transfer of results to customer databases or LIMS

Temperature Conditioning

Walter+Bai offers complete temperature conditioning solutions for ambient, low-temperature and high-temperature impact testing.

Available systems include:

• Ambient temperature testing
• Low-temperature testing down to −180 °C using LN₂ systems
• Cryogenic testing down to 20 K (−250 °C) using specialized cryogenic solutions
• High-temperature testing up to +900 °C or higher using customized furnace systems

Automatic specimen transfer ensures compliance with international standards requiring impact testing within only a few seconds after removing the specimen from the conditioning chamber.
