Should Heat Input Always Be Kept As Low As Possible?

Many ‘experts’ in the welding industry talk about high heat input as something that should always be avoided.  Unfortunately, this is not good advice.  High heat input can be detrimental in many cases, but other times we want to have higher heat input. Heat input is directly related to amperage and voltage and inversely related […]

How To Calculate Heat Input From Welding

The vast majority of fabricators are not typically concerned with heat input. For the most part this is OK. But when you are welding on materials whose microstructure can be significantly affected by welding procedures it is important to know about heat input. The reason why heat input is critical in certain applications is because […]
