TIME REQUIRED FOR BORE BUILDUP
(helpful when estimating job times)
Metric: Calculate by multiplying the diameter (mm) by the length (mm) by .002
Example: Diameter of the bore= 65mm; Length of the bore= 110mm
Normal build up time=65 x 110 x .002 =14.3 minutes
English: Calculate by multiplying the diameter (in.) by the length (in.) by 1.25
Example: Diameter of the bore= 4.2 inches; Length of the bore= 3.6 inches
Normal build up time=4.2 x 3.6 x 1.25 =18.9 minutes
WIRE DEPOSITION RATE
(useful when calculating anticipated wire usage)
Metric: Calculate by multiplying the following:
For .8mm wire- multiply the wire feed speed in mm/min by .00022
For .9mm wire- multiply the wire feed speed in mm/min by .00033
For 1.2mm wire- multiply the wire feed speed in mm/min by .00050
Example: Wirefeed rate= 7400mm/min; wire size= .8mm
Deposition rate= 7400 x .00022 = 1.63 kg/hr.
English: Calculate by multiplying the following:
For .030 in. wire- multiply the wire feed speed in in./min by .0123
For .035 in. wire- multiply the wire feed speed in in./min by .0167
For .045 in wire- multiply the wire feed speed in in./min by .0277
Example: Wirefeed rate= 320 in./min; wire size= .030 in.
Deposition rate= 320 x .0123 = 3.94 lb./hr
