Why choose micro-beam plasma welding instead of laser or TIG?

Compared with laser welding, it offers better control and lower cost. Compared with TIG, it provides higher precision and more consistent weld quality.

Product Q&A

Q:Will the thin diaphragm be burnt through or deformed during welding?

No. Micro-beam plasma welding provides highly concentrated heat with a very small heat-affected zone, ideal for ultra-thin diaphragms without burn-through or distortion.

Q:Is the inner circular weld accurate and consistent?

Yes. High-precision rotary control ensures excellent concentricity and smooth, uniform inner-circle weld seams.

Q:Does the weld meet high sealing and pressure requirements?

Absolutely. Dense and stable weld seams easily meet leak-tightness, pressure, and fatigue life requirements.

Q:Is the machine difficult to operate?

No. Recipe-based parameter control allows quick setup. Operators can run the machine with minimal training.

Q:Is it suitable for continuous mass production?

Yes. Stable arc performance and high repeatability ensure high yield for long-time continuous production.
