  • Using Gain to Optimize Weld Nugget Formation (.pdf)
    Gain at work is to think of a car radio. Car radios employ closed-loop control to keep audio output volume at a constant level regardless of how far the car is from the transmitter. As the car moves farther away, Gain increases to maintain the same audio output volume. Similarly, in welding, the Gain
  • Introducing a Control Solution for Weld Seam Normalizing (.pdf)
    EFD Induction has unveiled a new control system for normalizing pipe weld seams to API standards. Per H. Ødesneltvedt, one of the R&D engineers involved in the project, explains some of the system's features and benefits.
  • Introduction to SPC and Weld Checkers and Monitors (.pdf)
    Statistical Process Control (SPC) and Statistical Quality Control (SQC), are the buzzwords for manufacturing today. Most large manufacturers and many small ones are using these terms interchangeably to represent a method to improve quality, reduce rejects and improve yield. Weld Checkers
  • Energy Savings Tips for Ducted Weld Fume Systems
    it possible to use smaller, more energy efficient brake horsepower motors. The electrical savings potential for a simple ducted weld fume dust control system is at least $1800 per year, and significantly more for larger systems. Bell mouth-shaped hoods (Fig. 1), with an entry loss coefficient factor
  • The Importance of Force Control (.pdf)
    . When attempting to optimize the resistance welding process, many technical articles tend to focus on weld current and time to the exclusion of electrode force and the secondary variables. This Nugget will explain the importance of force control in production manufacturing environments. The heat
  • The Benefits of Closed-Loop Control for the Resistance Welding Process (.pdf)
    Closed-loop resistance welding power supplies use current and voltage feedback sensors to control the energy delivered to the parts. Closed-loop technologies provide many benefits for the resistance welding process. Taking full advantage of these benefits requires a good understanding of resistance
  • Medical Device Link . Improving Resistance Welding Process Control in Medical Applications
    Medical Device & Diagnostic Industry New systems enhance manufacturers' control over key variables during the welding process. During the past two decades, resistance welding has become a widespread method for joining metals in medical manufacturing applications such as biosensors, catheters
  • Medical Device Link .
    Software Gives Manufacturers Greater Process Control Programs facilitate information sharing and operations management To bring a device from the drawing board to the user, manufacturers must successfully accomplish a great number of individual processes, each with its own set of unique challenges
  • Keeping Your Welds on Track
    Critical to controlling any project's welding costs is the. ability to increase 'arc on time' and deposit as much weld. metal as possible (referred to as deposition rate) into as. many quality welds during every hour of the project. As. much as this is important, so too is controlling 'over weld
  • Laser Spot and Seam Welding of Titanium
    Titanium is a light, strong metal, known for corrosion resistance and bio compatibility. It is widely used in the expanding implanted medical device market and equally popular in Aerospace and high value jewelry. With fiber lasers, weld speed and power are the primary variables, and these control
