Energy storage welding equipment quality

What makes a good weld?

Innovative welding techniques can produce consistently better-quality joints. Special alloys, appropriate pre- and post-weld heat treatment, and proper weld procedures can all help prevent catastrophic failure of safety-critical systems.

Is there a quality assurance approach for laser welding?

Of course, if someone looks beyond the battery welding applications many in-process quality assurance approaches are available for welding . In the case of laser welding, the in- process monitoring is mainly based on imaging, acoustic emission, and E/M signal techniques in general .

What materials are used in welding?

The materials include low- and medium-alloy steels that have been specially developed for their high strength. Metallurgists have learned that heating joints prior to and after welding (pre-heating and post-heating) can reduce the sensitivity to cracking quite significantly.

Is laser welding better than other welding methods?

For the majority of applications, laser welding has shown an advantage compared to other ones such as Resistance Spot Welding, Ultrasonic Welding, or mechanical fastening .

How do you control a weld purge gas?

Purge gas oxygen content can be controlled by using special oxygen-monitoring instruments called Weld Purge Monitors. These instruments not only measure oxygen levels but will also inhibit welding if the level is above a setpoint predetermined by the operator. Recording and analyzing software provides information for quality-control purposes.
