As orbital welding is an automated or robotized process, a precise and repeatable preparation is absolutely necessary. In fact, if the preparations are not precise enough, as for instance a cut with a bandsaw on a stainless steel tube with a big diameter, the automated welding would not be possible or the results would be very poor.
The squaring of tubes is mostly done by a portable machine, that can be transported to the tube on site in order to prepare a high quality finish on tube installations, for example, for maintenance reasons. Due to the fact that this equipment is portable, they are commonly used.
During the squaring, the edge breaking tool will shape the tube section and enhances the surface quality better than any other cutting procedure. When precise surfaces are necessary, the squaring of the tube will be the most chosen solution.
Precise care of tube squaring is an operation that will offer two very interesting advantages according to the applications involved:

De facto, squaring permits to bring the tube edges in conformity after a cut by means of an non precise tool such as a grinding machine, band saws, guillotine saws, alternative saws. All these processes create important scratches at tube edge.
Only an orbital cut with its saw blade offers good quality and a straight and perpendicular cut. Orbital cutting is compatible with most demands.
However, squaring can also been done after an orbital cut in order to enhance even more the surface quality of the tube edge and therefore resulting in a high quality weld!
Our range of squaring machines DC has been developed for tubes having and external diameter from 3mm to 221mm with our models DC25, 65, 115 and 221. Here you can discover all products of our catalogue. You can download it free of charge!
