Open head or closed head : how to choose ?
With the closed head, the guarantee of high gas-shielded welding
With its compact width the closed head proves ideal on jobs that call for lower straight portions.
The protective atmosphere provided by the closed head allows for welding in an inert chamber. This provides a gas protection around the tube. It results in extremely clean lines on tubes which can be limited to a thickness of 2.7mm in stainless steel, while minimal and maximal diameters of tubes worked on will be between 6 and 114.3mm.
This type of equipment is used in industrial sectors requiring high levels of hygiene like for example in food processing, pharmaceuticals, semiconductor industry or aerospace industry. It is also recommended for welding elements in steel or in titanium.
Open head, for reduced clutter
With its compact rotating footprint and its different integrated motors (straight or bevel), open head proves ideal on sites requiring a low turning space.
Use it mostly for welding angles or to intervene on tubes that are too close to each other.
Because of the open nature of this model, it is possible to follow the weld. Be sure at all times to have the necessary equipment so as to be able to look at the weld without sustaining injury.
Models with cooling air are preferable if you are looking for a lightweight material or if your welding volume is moderate. They also stand out because of their attractive price. In the case of more demanding activity, opt for models with a water cooling system, which ensures a high yield.
Open head or closed head, all the advantages of orbital welding for your welds
Whether you opt for an open head or a closed head to carry out your work on tubes, you benefit from the high quality performance added by orbital welding. This technique guarantees you optimal quality that adheres to the strictest norms independent of the repeatability of the welds. Its advanced rotating torch process allows you to manage welds that are difficult to access, with the least difficulty. Easy to take in hand and to use, it completes the welders’ standard equipment.
The different types of heads and the available options will allow you to explore all the benefits of orbital welding.
