Applied Technical Services (ATS) provides brazing failure analysis to identify the causes of joint failures in compliance with ASTM, ASME, and ISO standards.
Brazing uses capillary action to distribute filler metal between two base metals, often resulting in joints stronger than the base materials. However, deviations in process control, excessive wear, or surface contamination can compromise joint integrity. Failure analysis identifies the root cause, supporting improved reliability and long-term performance.
What are Common Brazing Failure Modes?
Brazing defects can occur at any stage of a material’s lifecycle. These faults are typically caused by surface contamination, metal incompatibility, or process control deviations.
Common brazing failures include:
- Material Incompatibility
- Surface Contamination (stable oxides, oil, dirt)
- Thermal Fatigue
- Corrosion and Environmental Degradation
- Vibration
- Process Controls Deviation
- Poor Wetting or Lack of Bonding
- Voids or Porosity
- Mechanical Overload
How is Brazing Failure Identified?
Metallurgy labs use various methods to determine the root causeof failure. Accurate identification of brazing failures provides valuable insight for manufacturing, quality control, and corrective actions.
ATS metallurgy labs apply a wide range of testing methods for brazing failure analysis, including but not limited to:
- Cross-Sectioning and Metallography
- Microhardness Testing
- CT Scanning
- Scanning Electron Microscopy (SEM) with EDS
- X-ray Radiography
- Visual and Macroscopic Inspection
- Chemical Analysis
We identify failure modes from material selection through service life. Our comprehensive analysis addresses both brazing defects and in-service failures.
