100kw SOLID STATE HF TUBE WELDER

The Solid-State High-Frequency (H.F.) Welder is engineered for efficient, high-speed pipe welding across a broad spectrum of tube sizes and wall thicknesses. With power capacities ranging from 60 kW to 1200 kW and operating within a frequency band of 200 kHz to 450 kHz, this welder offers both flexibility and performance for various production needs.

A typical solid-state H.F. welding system includes several integrated components: a rectifier switchgear cabinet, an inverter output unit, fiber-optic control links, a soft water circulation cooling system, a centralized control console, and a mechanical adjustment mechanism for precision setup.

Renowned for its user-friendly operation, minimal maintenance, and consistent weld quality, this system has become a preferred choice in modern tube and pipe manufacturing lines.

100kw Solid State Welders FAQs

What is the difference between solid-state and vacuum tube HF welders?

Solid-state welders use transistors (IGBT or MOSFET) and offer higher energy efficiency, better stability, less maintenance, and longer lifespan compared to vacuum tube welders, which are bulkier and require frequent replacement.

Can the 100kW HF welder handle different pipe sizes?

Yes, within the supported range . For larger pipes, a higher power welder may be required.

What happens if the cooling system fails?

Overheating will trigger automatic protection and shutdown to avoid damage. It's essential to maintain stable cooling water pressure and temperature.

How often do I need to replace the impeder?

Impeder life depends on pipe material and usage frequency. On average, impeder rods should be checked and replaced every 1–3 months for optimal performance.

How much power consumption should I expect?

The welder consumes about 100–110 kWh when running at full power. Actual power usage depends on pipe size, thickness, and production speed.
