Supercharging Crash Prediction & Validating Spot Weld Quality with Virtual Weld-Rupture Simulations

Considering how easy it is to automate spot welding, it has historically been the most common joining process for high-volume manufacturing industries, such as the automotive industry. Learn to become more efficient in the assessment of spot weld quality while at the same time improve the predictiveness of crash safety simulations.

Automated spot welding is the primary joining method in high-volume manufacturing like the automotive industry. With a typical car containing over 3,000 spot welds of various types of alloys, steels and galvanized sheets, OEMs must accurately predict their strength early on so they can ensure structural integrity, safety and prevent costly setbacks in later stages.

Given that the amount of spot weld combinations can easily exceed 1 million, it is therefore not realistic to assess the quality and joining strength of each individual spot as it would be too costly and time-consuming.

To predict their robustness accurately and enhance vehicle integrity, ESI Group has developed a virtual solution that can help you improve your assessment of spot weld quality as well as the predictiveness of crash safety simulations.

Watch this webinar and learn how to:

  • Control and optimize spot weld process virtually to ensure required weld characteristics
  • Easily check robustness of the welding process through a weld lobe diagram
  • Integrate the welding history in virtual coupon rupture tests for more accurate prediction of force-displacement curves
