Heat Effected Zone

This might be a good way to remember the difference between effect and affect.

HAZ is common abbreviation for the ‘Heat Affected Zone’, the volume of the base material altered by heat from welding process.

I decided if a ‘Heat Effected Zone’ exists it should be the new volume created by the welding process, i.e. the weld pool or fusion line.
