Welding EnvironmentNon-contact inductive proximity sensors must perform a wide variety of clamping and nesting indication, and Poka-Yoke functions in harshwelding environments. Hot weld-spatter accumulation, elevated ambient temperatures, and strong electromagnetic fields emitted by weldguns can cause false triggering and degrade sensor performance.4Weld-spatterElectromagnetic Weld FieldsPROBLEMPROBLEMHot welding-spatter (a.k.a. weld debris, weld slag, weld berries)sticks to sensor faces and bodies and causes premature failure ofsensors in weld cells.Strong electromagnetic fields cause conventional sensors to falsetrigger or “chatter.”SOLUTIONSOLUTIONBalluff SpatterGuard coating on sensor faces resists weld debris andprovides a thermal barrier, significantly enhancing sensorlongevity, and reducing false triggering. PTFE coated sensor bodiesresist weld debris accumulation and promote weld-spatter removalduring regular scheduled maintenance periods.Balluff inductive proximity and magnetic field sensors with weld fieldimmunity (WFI) resist electromagnetic fields emitted by weld guns upto 100 kA/m.See page 18 or 24 to find your solutionSee page 20 or 22 to find your solution
Loading ImpactIncidental sensor damage caused by parts loading impact can significantly degrade sensor performance, shorten sensor life, or even destroya sensor. Balluff SteelFace inductive proximity sensors can withstand multiple heavy impacts and abrasion, and often have the sensingrange to be placed out of harm’s way.Damage from Loading ImpactSensor Face Damaged by ImpactPROBLEMPROBLEMSevere loading impact and continuous operational impact damagesplastic and/or PTFE sensor faces as well as sensor bodies.Standard tubular sensors often fail from damage to the sensor faceand coil caused by spatter and impact. Over time, small repeatedimpacts can damage the face and lead to sensor failure.SOLUTIONSOLUTIONEvery precaution should be taken to prevent electronics such assensors from being hit, but in many cases, loading impact cannot be avoided. By nesting a Balluff SteelFace inductive proximitysensor into a rugged Prox Mount or Bunker Block , the likelihoodof premature failure becomes lessened, even with repeated impactover time.Balluff SteelFace inductive proximity sensors with extended rangeand stainless steel housings resist impact, providing long life in weldcell impact zones. Balluff Bunker Blocks and PlungerProx provide sensors an extraordinary degree of physical protection,resisting or eliminating contact damage to the sensor body and faceas well as rapid sensor removal and replacement without need forrecalibration.See pages 34-36 to find your solutionSee page 18 to find your solutionwww.balluff.com5
Cylinder & Clamp PositionParts welded in a robotic weld cell must be nested and held in place by pneumatically or hydraulically actuated clamps which are oftenequipped with sensors located in the clamp jaws to indicate “clamped” or “unclamped” position. Clamp position can also be determined bymagnetic field sensors located on the outer wall of an aluminum or composite pneumatic cylinder. To determine clamping position, a BalluffBMF magnetoresistive sensor tracks the magnetic field emitted by a magnet attached to the cylinder’s piston.False Read Nut DetectionPremature Reed Switch FailureTipNo Tip6PROBLEMPROBLEMError proofing nut detection applications require sensors that cancome in contact without damaging the sensor. Standard sensor canfail due to contact to the sensor face.When installed on pneumatic clamping cylinders, failure-prone reedswitches and drift-prone Hall Effect sensors deteriorate, often providing inaccurate switch points before failing completely.SOLUTIONSOLUTIONBalluff PlungerProx with nut tip detects and error proofs componentsin harsh environments. The PlungerProx is offered in PNP and NPNwith four different tips to choose from providing a very flexible sensorsolution.Balluff BMF magnetoresistive sensors come with a lifetime warrantyand fit virtually all cylinder housing styles and brands. They provideprecise switch points and withstand the rigors of the weld process,while providing wear free, non-contact reliability.See page 16 to find your solutionSee page 28 to find your solution
Photoelectric SensorsPhotoelectric and fiber optic sensors require special protection and mounting expertise when integrated into welding cells. Balluff has a widerange of photoelectrics with application-specific infrared, red light, or laser capability that can reliably sense through smoke, oil and dirt. Inaddition, Balluff provides a range of accessories that protect photoelectric optics from heat, spatter, and lens occlusion in the hostile weldcell environment.Fiber Optic LimitationsDamage by Loading ImpactPROBLEMPROBLEMFiber optics can become occluded in the weld cell and stopfunctioning. They can become broken when weld fixtures areremoved, causing fibers to vibrate loose. Cables with excesslength break when tied back and get damaged by weld-spatter.Impact-prone photoelectric sensors can easily become physicallydamaged in welding environments.SOLUTIONSOLUTIONTypically, fiber optic solutions are not the best choice in weld cells.Metal-body laser sensors or inductive proximity sensors are almostalways a better choice.Bunker Blocks and Prox Mounts can be used to protect tubularphotoelectric sensors. They provide a thermal barrier, protect againstweld-spatter and impact, and provide rapid sensor change out.Bunker Blocks , available in several sizes and styles, protect blockstyle photoelectric sensors in the weld environment.See page 30 to find your solutionSee page 34 to find your solutionwww.balluff.com7
Protecting ConnectivityWeld cells demand the toughest connectivity solutions. Weld debris shortens the life of a cable in different fashions. Weld-spatter can buildup on the jacket, pulling the cable out of the connector. Weld sparks burn through the cable causing shorts in the connection, and theextreme environment temperatures can cook components. Balluff’s family of high durability cables were designed with weld environmentsin mind. The bodies of the connectors are weld spark immune with PTFE coated nuts to prevent spatter from sticking or burning theconnectors. This family has multiple cable jackets to endure different environments.8Sensor Cable Burn-ThroughNetwork I/O Blocks DamagedPROBLEMPROBLEMWeld-spatter burns through and destroys conventional cabling. It’sweight often pulls the cable away from the connector, exposing it toeven more damage.Sensor connections often terminate into plastic junction blocks ornetwork blocks which can easily be damaged in welding cells.SOLUTIONSOLUTIONBalluff engineered a new line of high durability cables to encompassevery part of the cable to withstand a welding environment. This lineof cables has a PTFE coated nut to prevent accumulation of debris,as well as a weld spark immune connector body to withstand suddenburst in temperature. Balluff tested different kinds of cable jackets inweld cells until finding our most durable cables: silicone tube,silicone cable, and PTFE cable. These different options keepproduction moving and reduce the number of cable replacements.A rugged line of industrial I/O products designed for use in theharshest environments offer a greater degree of strength anddurability for applications like robotic welding cells. Most major busand Ethernet based industrial networks are supported and providedetailed diagnostics on the connections from short circuit protectionto network status. In the dark confines of a weld cell, the bright andlarge LEDs are easy to see.See page 38 to find your solutionSee page 14 to find your solution
Non-Contact CouplingInterchangeable weld fixtures and rotating weld tables often require the use of troublesome, expensive, and high-maintenancecontact-based rotating assemblies such as slip rings or commutator ring/brush solutions. In many cases wires inevitably fray and break.In contrast, Balluff’s unique non-contact connectors provide a wear free connectivity, powering sensors and providing control informationacross an air gap.Broken or Worn Out Communicator RingsPROBLEMRotational weld cells, or cells that use interchangeable fixtures, oftenincur high maintenance and frequent stoppages due to damagedslip rings, tangled, over-flexed, or twisted wiring.SOLUTIONNon-contact connector systems provide communication betweentwo or more separated weld cell components through an air gap toenergize and communicate between the controller and the sensors.Since there is no hard wired connection, weld fixtures can be inserted into a weld cell frame without the need for mechanicalconnections, facilitating rapid change out.Any place with an A-side/B-side or 360º rotating table needsconnections across an axis of rotation. The non-contact couplerfrom Balluff provides transparent connection between the sensorsand controller. Since it is non-contact, it is completely wear-free andhas dramatically reduced repair and downtime versus many traditional connection methods.How Non-Contact Couplers WorkThink of this like a mechanical connector without pins or therequirement of physical contact. When connected, power goes outto the devices and signals come back from the devices. Dependingon the specific product of interest, different information can bepassed. Power only or power plus, discrete inputs and outputs, oranalog voltage signals can be transmitted across the air gap. Eachbase head is mounted on the controller side of the application andas many remote heads as needed are mounted on the sensors/actuators side of the application. 15mmMultiple SensorsRemoteSignalPowerSee www.balluff.us/bic to find your erInductive Coupling9
Weld Sensing Best PracticesSelecting Components for SurvivabilityWhen working in harsh environments and in heavy duty applications like welding, it is important to take a multi-angle approach to designingthe application. When you are working with existing sensor installations, it is important to consider all the reasons for the sensor’s failurebefore determining a winning solution. While blind trial and error will eventually lead to improvements in sensor life, Balluff has developed withour customers a strong best-practice approach for applying sensors in automated welding.1. Select the Right SensorWhen selecting the right sensor, you have to take into account multiple aspects of the application:how the sensor is being used, what environment is it being exposed to, and why the current installationhas continuously failed. Common questions to consider are:Environmentaln Will the sensor signal be affected by the weld noise?n Is the sensor failing due to heat from the environment?n Is there excessive weld-spatter accumulation on the sensor?Applicationn Does a different sensor technology make more sense?n Can I detect this part from a different angle or location?n Is there a better mounting solution for the sensor?Balluff offers many combinations of sensor technologies for use in the welding environment, and the besttechnology may require some testing before it can be determined.10
2. Protect the SensorWhen determining how much protection is needed for the sensor, you still have to consider these typicalquestions: what is the sensor being exposed to and why is the current installation failing. Other commonquestions to consider are:n What available space do I have?n Is there physical contact damage to the existing sensor?n Can I change the tooling in any way?Balluff offers one of the widest varieties of accessories specifically designed for applying sensors in thewelding environment. The best accessory for your specific application may require adaptation of thetooling for implementation.3. Connect with ProtectionProtecting the connection between the controller and the sensor can be as much of a pain point askeeping the sensor alive. Whether the sensor cable fails from weld-spatter buildup or from physicaldamage from contact with a part, the cable can be the lynchpin to a successful weld-sensingapplication. Questions to consider when looking at connectivity options:n Is the cable collecting spatter or melting from contact with spatter?n Is the connector not meeting the proper bend radius and being damaged?n What temperatures and environments will the cable be exposed to?Balluff offers the strongest options of sensor connectors for your welding applications. These productshave been tested in real-world customer applications and extended the life of an application more than50 times in some instances.4. Learn with Continuous ImprovementThere are some things worth doing over and over, but replacing a proximity sensor every shift is not oneof them. By learning from our failures and analyzing them we can increase our productivity, improve ourquality, and reduce headaches for operators, technicians, and even managers. So when a sensor fails, itis best to document the failure and then begin to make a plan to improve the application. Somequestions to consider at a failed sensor application include the following:n What caused the eventual end of the sensor? Heat? Spatter? Impact?n What else is damaging the sensor? Is the cable failing?n Where else do we have a similar installation or application?While we understand that time is tight and downtime costs money, there isn’t always the luxury toanalyze for yourself what is going on in the facility: you are just trying to keep it running. Balluff offersmany opportunities for training or service where we can help you improve the skill set of the techniciansor bring in extra labor to implement improvements.www.balluff.com11
