Weld Profile Training
You use Weld Profile Training to create training files for the welds you consider acceptable when a Weld
Operator uses that specific Weld Profile. Training helps you generate limits for current, voltage, wire feed
speed and duration for a Weld Profile automatically. Training a weld also generates the necessary data in
order to use WeldScore™. You generally perform three to five training welds in the same manner as they
would be made in normal production. This provides you with a good average on the weld and allows a bit
of flexibility when making welds in production. If you make any welds during training that are outside of
the acceptable limits, you can simply remove those welds from the training.
STOP | You must train a Weld Profile in order for the power source
to provide a WeldScore™.
If your intent is to train a weld to implement WeldScore™ (available on third-generation machines), due to
the volume of data required when training for WeldScore™, the longest weld you can perform for training is
up to 60 seconds (one minute) in duration for a meaningful WeldScore™. Otherwise, the power source
begins to overwrite the old data in the buffer and the WeldScore™ for that Weld Profile will not be
accurate.
On second-generation power sources that do not support WeldScore™, you can still use training models to
help you set limits for current, voltage, wire feed speed and duration. The longest weld you can train is up
to 1260 seconds (21 minutes) before the power source begins to overwrite the data in the buffer. When
you create those training files for each Weld Profile, the power source calculates the limits for you
automatically. You can adjust those calculated limits under Production Monitoring > Configuration >
Profile limits in Power Wave® Manager (page 10.7).
Welds to Train
You should train each Weld Profile that is being used for shorter welds where the welds are consistent and
repeatable. The longer the weld, the less consistent and the less repeatable it becomes. You must train
any Weld Profile you want to use to implement WeldScore™. WeldScore™ works by comparing production
welds to welds that have been trained. In order for an accurate score to be assigned, you should train
between three to five welds at each allowable production extreme for each Weld Profile.
For example, John at Advanced Manufacturing has a weld where the electrical stickout is allowed to vary
from 5/8” to 3/4”. He trained five welds, one at each of these stickouts.
Only train the allowable extremes for the weld. For example, if the stickout can increase to 1” but you
consider this out of limits for an acceptable weld, do not include this in the training. The purpose of
training is to demonstrate to the Welding Power Source the types of welds you consider acceptable.
