Why Weldotherm WTD

Equipment that makes heat treatment precise, safe and reliable.

Resistance Machine

Here, current is passed through a resistor, which converts the energy into heat. This allows metal workpieces to be heated evenly and precisely.

Technical Data

Power: 12 – 288 kW
Connected load: 400V (63 – 188A)
Control voltage: 230V at 50Hz
Primary connection: 4x6 mm² (32A) – 4x185 mm² (440A)
Program controller: 2 – 12
Control circuits: 2 – 12
Switching current /RK: 90A – 360A

Induction Machine

Electromagnetic fields generate heat directly within the component. This enables rapid and precise heating, ideal for complex shapes and demanding applications.

Technical Data

Power: 40 – 160 kW
Connection rating: 400V (63 – 250A)
Primary connection: 4x16mm² - direct connection
Secondary voltage: max. 500VAC/1000VAC
Secondary current: max. 400A/750A/900A/1000A
Frequency range: 3 – 18 kHz
Noise level: <70dB

Gas Burner Trolley

This mobile device uses gas and heats workpieces flexibly and directly on-site. This allows even large or difficult-to-handle components to be treated with precision.

Technical Data

Fan connection voltage/power: 400V – 16A
Inlet pressure: 3 – 5 bar
Working pressure: 0.2 bar
Gas: Natural gas | Propane
Power: Natural gas 1000 kW | Propane 800 kW
Consumption: Natural gas 5-100 m³/h | Propane 1.5 – 30 m³/h, max. temperature: 1200°

Hybrid Temperature Recorder

This records temperature curves during heat treatment and combines analog and digital measurement methods to precisely monitor and seamlessly document processes.

Technical Data

12 channels
100 to 240 VAC, 50/60 Hz
Documentation, paper, and SD card
Flexible use
Use according to your needs
Can also be used as an additional recorder

Why equipment is an indicator of quality

The technical foundation for heat treatment

The quality of a heat treatment process begins with the equipment. Modern, powerful, and precise equipment forms the foundation for safe, reproducible processes and optimal material properties. Only with reliable resistance and induction systems, flexible gas burner carts, and hybrid temperature recorders can temperature profiles be precisely controlled and documented. The higher the quality of the technical basis, the higher the process reliability, efficiency, and quality of the results. This therefore serves as a direct indicator of the company's reliability and expertise.

Heat treatment with responsibility and know-how for over 50 years.

Resistance, induction, or gas. We deliver the right solution for every geometry, every size, and every requirement.
