Strecker butt welders now also with pyrometer annealing for thin wires
Since 1933 August Strecker is known for its high quality wire and/or cable buttwelding machines, supplied to customers in more than 110 countries all over the world. The welders come with a "5 years' warranty", a proof of their reliability and longevity.
Especially when welding steel wires, there will be a "heat affected zone" that is quite brittle and requires annealing to obtain a smooth transition from the original material to the "HAZ" and make the material workable again, e.g. to avoid wire breaks in further stages of production.
The annealing process may be controlled manually by the operator deciding on annealing temperature and time. Alternatively you may choose to have a time-relay to set the annealing time. Or there is the option to have a programmable microprocessor control to store parameter sets for the welding and annealing process. The most precise solution is of course using a programmable pyrometer.
So far pyrometer annealing was a solution for wire diameters of 4,0 mm and bigger, as smaller wires bended out of the pyrometer's optical measuring point when being heated up. Using a pyrometer with an oscillating measuring spot, pyrometers are now available for smaller wire diameters, too. Usually the welders come with a "FPC - Full Parameter Control" to store parameter sets for more than 100 different steel wire sizes and qualities. This includes the pre-set data for the pyrometer comparing the stored annealing values with the actual annealing values in each cycle and correcting them immediately.
