WELD ACTUATOR
Rod-End Load Cell
Model WRE

WELD FORCE & TIP STICKING

FORCE RANGES TO 10,000 LBS.

FATIGUE RATED, VIBRATION PROOF

NIST TRACKABLE ACCURACY 0.5%

SIDE-LOAD RESISTANT

The WRE Rod-End Load Cell has been specifically designed for weld guns and stationary weld machines. This load cell measures dynamic, real-time forces transmitted directly to the resist-servo actuators. It can be integrated into a wide variety of pedestal spot and projection welders and various seam welding machines.

The WRE Rod-End measures actual weld force applied to the electrodes from initial tip contact, through nugget growth, to final release. Its unique design provides excellent side load resistance and produces accurate compression and tension load signals.  Compression load measures the applied force while tension output can be used to indicate the force associated with sticking weld tips.

Interfaces with a variety of digital electronic instrumentation, the WRE Rod-End can ensure proper weld force in achieved and maintained throughout the weld cycle. Accurate force information can help detect nugget growth and indicate expulsion and weld tip sticking. Using pre-set force limits, the WRE is used to fire current at a predetermined force level ensuring current is fired at exactly the right time while eliminating unnecessary squeeze time.

OPTIONS

The WRE Rod-End load cell is interfaced with a variety of instruments and signal conditioners. We offer a WM9000 WeldMeter which is a multi-channel device providing a complete signal conditioning system for up to 14 channels. A variety of features include limits, auto zeroing and external tare. Various relay configurations and analog and digital output signals are avaliable.

The WM9000 can be used with the WRE load cell to trigger current firing based on preset force limits. A second limit can be used to alarm when force exceeds another preset limit. This configuration can help ensure that proper force is achieved and maintained during current firing and can also help to minimize unnecessary squeeze time.

For advanced signal monitoring, tracking and analysis, interface the WRE Rod-End load cell to a variety of commercially available weld monitors. Inquire for more details.
