Weld monitors have been available for many years. Unfortunately, most of these
devices are either current, or milli-volt second monitors, neither of which
satisfy the basic requirement. To properly evaluate a weld, we must establish a
correlation with what is happening electronically, and the mechanical test
results. To do this we must have weld monitoring instrumentation capable of
providing the necessary information. To properly monitor a weld, the equipment
must measure current and area under the curve on each half cycle in A.C.
applications, and measure current and area under the curve for each weld in
D.C. applications. Further, it must be capable of calculating the product of
these and reporting in half cycle increments, for A.C. applications. This
product is called the weld energy, which is expressed in watt-seconds or
H is the heat energy developed in each weld.
I is the current in amperes.
R is the resistance in ohms.
is the time in milliseconds, or microseconds.
Finally, the weld monitor must be capable of accepting both upper and lower
control limits with alarms to alert, or shut down the process.
Only Welding & Automation, Inc. offers such a device. The optional weld
monitor is an intregal part of the Series 2000 Weld Control, and measures
energy in real time, unlike remote add on monitors. It is fully programmable
for upper and lower process control limits. The weld monitor audits every half
cycle of the weld, capturing the readings for current (in amperes) and
milli-volt seconds (area under the curve). The product of these is expressed in
joules of energy for each half cycle. The weld monitor protects against process
shifts caused by dirty or worn electrodes, dirty or inconsistent product,
equipment malfunctions, and countless other variables. The weld monitor stores
the readings in memory for downloading to SPC packages for process capability
analysis, or to printers for charting and evaluation.
