Welding Appliance Housings: Three Requirements at Once

Appliance housings are large plastic parts with high appearance standards, accumulated tolerance and output pressure. What each constraint costs, and where the trade-offs are.

Lamps and Sealed Parts: Leak-Tight Is Not the Same as Strong

Sealed parts are judged on leakage, and a joint strong enough to pass a pull test may still leak. How sealing work differs from structural welding.

Ultrasonic, Resistance or Laser: Choosing a Metal Joining Method

Three common methods, three ranges of application. Ultrasonic is solid-state and suits dissimilar and highly conductive metals; resistance is simple; laser is fast.

Why Medical Disposables Are Welded Rather Than Glued

Adhesive introduces a foreign substance, with residue, biocompatibility and cure control to manage. An ultrasonic weld is the parent material itself.

Why Battery Tab Welding Carries Such Tight Process Requirements

Battery tabs are thin, soft and conductive; the process must add almost no heat, keep joint resistance low, and record every weld. Why solid-state joining fits.
