Weld preheating involves heating a section of, or the entire part, to a specific desired temperature, generally referred to as the preheat temperature.

The heating may or may not continue during welding, dependent on the heat generated by the arc. The goal is to maintain a certain temperature from the first weld pass to the last.

Preheating produce several very beneficial effects, including producing a more ductile metallurgical structure that cracks less, helps in releasing trapped hydrogen, and reduces stress cracking during cooling.

It is always recommended that you should consult with weld heating experts and learn the fundamentals of this process in order to avoid costly errors in preparation or wasting money on the using the wrong equipment.



Here is a very general diagram of the typical welding pre-heat equipment layout.
