Post weld heat treatment is a method of reducing residual stresses in welded joints. Joints are wrapped in ceramic pad heating elements and heated according to a specific ramp/soak sequence, often applied across multiple heating zones simultaneously.
EPC2000 controllers provide a cost-effective method of clustering multiple single loops in a compact console built into a portable trolley.
One unit is configured as a master programmer, broadcasting a setpoint to several slave units. Each slave uses a deviation alarm relay to close a digital input on the master unit if it has not yet approached setpoint, to provide a holdback or “guaranteed soak” function in each zone.
Using the recipe function on the EPC2000 instrument, units can be easily reconfigured Semiconductor Etch Processes Real World Applications with a digital input, permitting a console to be subdivided into switchable sets running different profiles at the same time for separate operations.
