Weldotherm® heating and preheating elements are robust heating elements which are particularly stable and durable, and optimally transfer heat to the workpiece.
Our premium heating elements heat the workpiece both reliably and accurately to the desired temperature. They are equipped with the "DINSE" plug system or also with the English Camlock system, if required. Available with Teflon or ceramic insulated tails.
Heating tapesThese robust heating tapes can be customised to the workpiece particularly well and are the ideal heating element for circumferential welds on pipes, pipe walls and arches, bends and seams, that are difficult to access. In addition, they also serve to dress flanges and fitting connections. Application limit: 1050°C.
One-line-heating cablesOur one-line-heating cables has an outer sheath made of austenite wire mesh, making the shell flexible and heat-resistant. Ideal for welds on pressure vessels, flange connection welds and boiler walls, fittings and shaped part connection welds, in addition to superheater pipes, as well as small ones. Application limit: 1050°C.
PreheaterPreheater have a back insulation which is made of 25mm ceramic fibre in Inconel wire mesh and the back protector is made of stainless steel sheet. Application areas include circumferential welds on pipes, connections on pressure vessels, circumferential tank welds and longitudinal tank welds. Application limit: 450°C.
Magnetic PreheaterOur magnetic preheater are equipped with high temperature resistant magnets. Its back insulation is made of 25mm ceramic fibre in Inconel wire mesh and the back protector is made of stainless steel sheet. Application areas include circumferential welds on pipes, connections on pressure vessels, circumferential tank welds and longitudinal tank welds. Application limit: 450°C.
Flexible Heater – WraparoundsIf the same tube diameter must be heat treated often, the wraparounds save time and money. This flexible heaters are custom made for the appropriate diameter and reduce set-up times to a minimum, since no time consuming fixing of heaters and insulation material is required. Application limit: 950°C, for wraparounds with thermocouple bayonet elements max. 800°C.
Magnetic Heating BoxesThree high temperature resistant specialist magnets independently hold the magnet preheater in its place. The back insulation is made of 25mm ceramic fibre in Inconel wire mesh, the back protector is a robust box construction made of stainless steel with handles for ease of use. Ideal for longitudinal plate welds in shipbuilding, on box girders of steel constructions and straight tank welds. Application limit: 450°C.
Weldotherm® offers coil and fixed inductors which can be used for a variety of applications. In addition, we also manufacture air- and water cooled inductors for units that are made by other manufacturers.
