Acid Etch Examination

Acid Etch Testing

A form of destructive weld testing, acid etch exams are used to evaluate weld characteristics, analyze metal failure, and determine weld integrity. An expert in metallurgical testing and failure analysis, MSi Testing performs acid etch tests on a full range of corrosion-resistant metals and alloys. We proudly serve the needs of the automotive, construction, aerospace, food & beverage, manufacturing and other industries, and our team of chemists performs all acid etch exams to meet your project and budget objectives.

Used to test weld and metal quality and performance, acid macroetch testing can reveal the presence and degree of surface conditions and imperfections, including:

  • Porosity
  • Cracks
  • Alloy segregation
  • Thermal flaking
  • Seams
  • Presence of foreign materials
  • Poor fusion

In addition to acid etch testing, MSi’s team of degreed engineers uses state-of-the-art equipment to perform other metallurgical and chemical analyses. Test types include:

  • OES Spectroscopy
  • ICP Metal Analysis
  • XRF Analysis
  • LECO Analysis (carbon, sulfur, oxygen, nitrogen, hydrogen)
  • Microwave Digestion
  • Alloy Verification & Identification
  • Positive Material Identification Testing
  • Re-melt Capability

Depending upon your sample size and usage requirements, MSi metal experts recommend the tests that achieve your goals—affordably and accurately. When your acid etch exam is complete, you will receive a detailed assessment of macroetch results and further recommendations. For your convenience, we boast the industry’s leading turnaround times—including same-day options for some tests and metallurgical procedures.
