Fundamentals Of Welding Parameter Development

In arc welding processes a multitude of welding parameters exist that can effect the size, shape, quality and consistency of the weld. Many weld parameters (weld variables) exist and each can form the basis for a lengthy discussion. It is imperative however, that the engineer responsible for welding have at minimum, an understanding of how to choose and modify the basic parameters for simple weld applications. Listed below are the fundamental issues to understand.

  • Welding Physics: The sequence of a typical welding program, arc starting, arc voltage, weld current, heat input(watt-secs)

  • Weld Current: Rules of thumb for choosing the correct weld current. How to recognize insufficient or excess weld current.

  • Arc length: How to choose the correct arc length. What happens when the arc length is too long or too short.

  • The effect of weld speed. What happens when the weld speed is too fast or too slow.

  • The 6 benefits of Arc Pulsation. How to choose the pulsing rates empirically or from pre-calculation.
