Weld Monitoring in Automotive/Transportation Industry
Resistance Spot Welding (RSW) is a critical welding process useful for stainless steel vehicle manufacturing in the automotive or transportation industry. There are many advantages of RSW. Some of them are as follows –
- RSW is an economic welding process
- RSW is highly adaptable to a wide range of materials as well as thickness
- RSW is a process with a short cycle time
- RSW is a robust process with some level of tolerance to individual variations
A weld monitor or a weld data monitoring system using arc timer or sensory arc timer, even welding arc timer, is useful for monitoring real-time welding and visualization of variations during the RSW process. Thus, the Weld monitor or the welding control equipment will help the online evaluation of welding quality.
In the last few years, non-intrusive electronic sensors such as weld monitor current sensors, algorithms processing the signal, and computational intelligence such as Weld Counter help the industry. Soldered with drastic reductions in computing and network hardware costs, they are possibly developing independent, intelligent resistance spot welding systems that overcome all the above shortcomings.
