Laser Welding

Laser Welding Overview

Laser welding is useful in a variety of situations and product applications. One of the best use cases is for welding spring energizers. Through many years in the business, we've found that one of the most common contributors to seal failures is an improper or missing energizer spring weld.

An improper weld can lead to a "high point" on the sealing lip which causes uneven pressure, leading to premature wear and part failure. When a spring weld is missing, the spring cannot provide adequate evenly distributed support, leading to support gaps and possible part failure. Laser welding creates a precise weld, allowing for even distribution of load to ensure proper sealing.
