ATS offers heat treating services for many industries in the southeast

As an industry leader in weld heat treatment companies, ATS offers quality engineering, testing and inspection services. We have earned an excellent reputation in customer service, adhering to safety standards, and offering a wide variety of services performed by professional/knowledgeable experts.

With high demands from many industries, ATS offers electrical resistance heat treatment services throughout the Southeast. This treatment may benefit many of our current and potential new clients who are in the process of receiving other ATS engineering, testing, and nondestructive inspection services.


Heat Treatment Objective & Method
Objective:

Heat Treating is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product’s shape. Noted benefits to this treatment are increasing the strength of material or achieving certain manufacturability objectives like improved machining, improved formability, or restore ductility after a cold working operation. In addition to the manufacturing benefits, many industries may rely on this process for better product performance due to increase strength and other desirable physical characteristics.

Method:
  • ATS' equipment uses 480 volt three phase (high voltage) power to supply 6 circuits of 85 volt (low voltage) to power electric resistance heating pads
  • Quality equipment and technology capable of heating from 100°F to ambient to 2,400°F +
  • Treatment accurately and efficiently performed with proper documentation according to stringent Quality Assurance Procedures and Standards
  • Utilizes NIST-traceable recorders and thermocouples for accurate documentation
Why Pre & Post Weld Heat Treatment (PWHT)?
Benefits for Preheating:

The goal of preheating is to reduce the cooling rate of the base metal and deposited weld metal.

Method:
  • Uniform heat penetration
  • Maintaining specific minimum temperatures
  • Less downtime with components always ready to weld
  • Welder productivity for faster turnarounds
  • Eliminates manual preheat example "rosebuds"
  • Eliminates any open flames reducing a major SAFETY issue
  • Recordable documentation of preheat

Benefits for Post Weld Heat Treatment (PWHT):

Post Weld Heat Treatment or Stress Relief is a crucial step in maximizing the life of process equipment. PWHT tempers the metal and reduces tensile stresses, minimizing the risk of brittle fracture, stress and corrosion cracking and metal fatigue. This is especially important for equipment used in harsh service environments for examples Refiners and Utility Industries.
