Welding Cfh Meaning. The heat may be supplied by electricity or by a gas flame. However there is no such thing as one size fits all solution.
Maintaining the correct CFH is critical to ensure a smooth weld. With stainless the chromium mixed into the alloy can burn off on the back side of the weld as well as the front side. Without sufficient CFH your weld pool can be infected by outside chemicals like particulate matter floating in the air or unwanted gasses.
The heat may be supplied by electricity or by a gas flame.
For a better understanding of this pressure welding professionals use another term called CFM or cubic feet per minute. It is effective when used for non-structural fusion welding heating and brazing. Theres a common misconception among fabricators that more cubic feet per hour CFH is always better. Multiply the BTU number that needs to be converted by the correct factor from the equation depending on whether natural gas or liquid propane is being used.
