HF profile and tube welding units Easy tubular pipes can also be manufactured by DREISTERN tube welding installations. Its true strong points may however be videnced by demanding tasks. Should you, for instance, have to produce stainless steel tubes of outstanding quality or contoured tubes with complex cross-sections, then you ought to consult our specialists. Good solutions are seldom exclusively a question of modern plant components. Convincing concepts originate from dialogues between the users and the machine manufacturer. DREISTERN guarantees you a competent, experienced team. Hardly any DREISTERN machine is like another. They are as varied as our customers and their requirements. Perhaps that is what makes them so successful.
Laser profile and tube welding installations For some profile and tube manufactures laser technology is still new territory. In fact, a lot of questions are being asked about this technology. The initial question is frequently: Is laser really the right solution? More and more frequently our customers answer affirmatively. The reasons are numerous. High seam quality, low heat-affect on tubing material, complicated seam welding positions are but a few of the key-words which have been attributed. Although such laser applications can be impressively successful, without careful process analysis great risks could be lying in wait. You certainly cannot afford any costly experiments? Why don't you contact us? DREISTERN has lots of experience thanks to the many welding processes which have already been supplied.
TIG profile and tube welding units Your requirements do not allow for any compromise? Complicated forms or welding materials? We certainly do not always have the solution. Our experience with numerous demanding applications gives us however, the necessary sureness that sometimes technical boundaries may be overcome. An example: With our RSD50 thin-walled tube welding unit, we attain extraordinary diameter/ thickness ratios and excellent seam quality. Even without seam processing, the seam is hardly visible. Speed? Your production process could possibly have problems to keep up with the pace.
Composite tube manufacturing lines Aluminum-plastic composite tubes are constantly being used in new applications. The reasons are quick installation, corrosion-resistance, and last but not least, lower costs. Hot/cold water pipes and chemical tubes are but a few of the many possible applications.

Production units for composite profiles What are composite profiles Composite profiles are composed of two or more strips or profiles, which are permanently bonded to each other e.g. by laser welding. Components can be of different thickness or even composed of different metals.
	Up till now, profiles were of uniform thickness. Composite profiles, on the other hand, are provided with a reduced thickness in areas of less strain and a slightly increased sheet metal thickness in areas of greater strain. This saves material. In this particular case nearly 30%, while still allowing for the same strength in the horizontal axis.
	Rollforming tools for complex profile shapes have to be tested at length and cause long tool change-over and set-up times. Thanks to composite profiles, profile complexity is drastically reduced. For example a lap can be replaced by a flat base. The number of forming stations can be reduced by 50%. Testing and change-over time can be saved down correspondingly.
	Punching patterns are deforming often during rollforming or cause deformations to the profile shape. Composite profiles are different: All punching and bending operations are carried out on the flat strip. The functional elements produced in that way do not undergo any forming process, but are continually welded in line to the base profile. The result: Precision parts without any deformation to the punching pattern or to the profile form.
