Strecker Success Story Reliably weld large cross-sections
Avoid system downtime

The challenge

The intention when joining large stranded conductor cross-sections was to avoid unwinding the outer layers to obtain a smaller outer conductor diameter for easier welding. Crimping or using connectors was also to be avoided. And stopping the extruder was an absolute no go due to the hours of effort required afterwards to clean the worm gears.

What is known as the “chamber welding process” uses ceramic tubes, such as STRECKER type SE300 with a welding range for copper conductors of 95-1200 mm². But this was not the first choice here because a lot can be done wrong when preparing the conductor ends to be welded, selecting the tube and setting the individual parameters. The dependence on the experience and the skill of the individual operator is simply too high in this process.

There was a need for a reliable, accurately repeatable welding method that could be carried out safely and conveniently by semi-skilled personnel.

The solution

An electrical double-upset butt welding machine with integrated automatic deburring and fully hydraulic motion sequences (clamping, the double upset process and deburring), that can weld completely without tubes so that the operator always has the work sequence in full view.

Here: The STRECKER Type MK1200, welding range for copper stranded conductors, 185-3000 mm².

Innovation from Strecker
Strecker Type MK1200-FPC

  • Excellent weld quality due to double upsetting; nearly all the heated and therefore molten material is pressed out of the joint, which produces a weld with extremely high strength.

  • The automatic deburring integrated into the process provides welded joints with exactly the same diameter as the original material. This eliminates the need for the tedious, manual rework (filing) of the weld that is required as a rule when welding machines are employed that operate using tubes.

    The result is not only enormous time savings, but also simplification of the operator's work.

    Additionally, this avoids the risk of breakage due to excessive deburring, i.e. a reduction of the cross-section at the welded joint.

  • The machine offers simple, user-friendly handling. All of the recipes for different cross-sections and materials are saved in the controller where they are password protected from unauthorized access or modifications.

  • Repeatable, exactly reproducible welded joints of the highest quality with a uniform diameter form a solid, reliable basis for further manufacturing processes and contribute to quality assurance.

The result

Using the machine Type MK1200 reduced downtimes and increased productivity.

Operators appreciate the simple handling, especially the integrated recipe management.
