6. Describing GMAW processes¶
6.1. Imports¶
[1]:
import weldx
from weldx import Q_
from weldx.core import TimeSeries as TS
from weldx.welding.processes import GmawProcess
6.2. spray arc processes¶
[2]:
# Note: For some reasons, using integers in Q_ fails upon ASDF reading !
params_spray = dict(
wire_feedrate=Q_(10.0, "m/min"),
voltage=TS(data=Q_([40.0,20.0], "V"),time=Q_([0.0,10.0],"s")),
impedance=Q_(10.0, "percent"),
characteristic=Q_(5,"V/A"),
)
process_spray = GmawProcess(
"spray", "CLOOS", "Quinto", params_spray, tag="CLOOS/spray_arc"
)
6.3. pulsed arc processes¶
6.3.1. UI modulation¶
[3]:
params_pulse = dict(
wire_feedrate=Q_(10.0, "m/min"),
pulse_voltage=Q_(40.0, "V"),
pulse_duration=Q_(5.0, "ms"),
pulse_frequency=Q_(100.0, "Hz"),
base_current=Q_(60.0, "A"),
)
process_pulse = GmawProcess(
"pulse",
"CLOOS",
"Quinto",
params_pulse,
tag="CLOOS/pulse",
meta={"modulation": "UI"},
)
6.3.2. II modulation¶
[4]:
params_pulse_II = dict(
wire_feedrate=Q_(10.0, "m/min"),
pulse_current=Q_(0.3, "kA"),
pulse_duration=Q_(5.0, "ms"),
pulse_frequency=Q_(100.0, "Hz"),
base_current=Q_(60.0, "A"),
)
process_pulse_II = GmawProcess(
"pulse",
"CLOOS",
"Quinto",
params_pulse_II,
tag="CLOOS/pulse",
meta={"modulation": "II"},
)
6.4. using ASDF¶
We write the dictionary containing our structured data to an ASDF file using the WeldxFile class. We pass the tree as a named keyword argument. The tree will be serialized to ASDF in memory, and we can have a look at the ASDF header.
[5]:
tree = {"spray": process_spray, "pulse_UI": process_pulse, "pulse_II": process_pulse_II}
[6]:
file = weldx.WeldxFile(tree=tree)
file.show_asdf_header()
