Abstract
Sposób zgrzewania rezystancyjnego, zwłaszcza punktowego w warunkach ekspulsji, prowadzi się urządzeniem zgrzewającym o częstotliwości ponad 10 kHz w etapach, a podczas zgrzewania mierzy się wartość co najmniej jednego parametru zgrzewania, przy czym parametry zgrzewania poddaje się kontroli w czasie rzeczywistym, a dla stwierdzonych ponadnormatywnych odchyłek od wielkości zadanych w czasie 0.3 ms - 1.0 ms ustala się wpływ na uzyskanie nominalnej wartości jądra zgrzeiny i koryguje się wartość następnego impulsu danego parametru lub dopuszcza się parametr z odchyłką, natomiast dla mierzonego w czasie detekcji td parametru siły docisku elektrod w warunkach ekspulsji dla odchyłki większej lub równej 10% wartości zadanej wstrzymuje się przepływ prądu zgrzewania Izg1 na czas tp, ustala się wartość drugiego impulsu prądu zgrzewania w zależności od czasu trwania zgrzewania i wznawia się dostarczanie prądu zgrzewania Izg21. Zgrzewarka inwertorowa, zwłaszcza do zgrzewania rezystancyjnego punktowego o częstotliwości 10 kHz i wyższej, wyposażona jest w układ sterowania zgrzewarki USZg (7) oraz układ wykrywania wyprysku oraz zawiera sekcję przemiennika częstotliwości PCz (1), transformator zgrzewarki Tr (2), prostownik wysokoprądowy P (3), elektrody zgrzewarki (4). W układzie docisku elektrod czujnik siły docisku elektrod CSDE (5) wyjściem sygnałowym jest podłączony do wejścia analizatora AN (6), a wyjście analizatora jest podłączone do układu sterowania zgrzewarki USZg (7), który steruje blokiem przemiennika częstotliwości PCz (1).The method of resistance welding, especially spot welding under expulsion conditions, is carried out with a welding device with a frequency of more than 10 kHz in stages, and during welding the value of at least one welding parameter is measured, while the welding parameters are checked in real time, and for excessive normative deviations found from the set values in the time of 0.3 ms - 1.0 ms the effect on obtaining the nominal value of the weld core is determined and the value of the next pulse of the given parameter is corrected or a parameter with a deviation is allowed, while for the td measured during the detection of the td parameter of the electrode pressure force in the expulsion conditions for the deviation greater than or equal to 10% of the set value, the welding current Izg1 is stopped for the time tp, the value of the second welding current pulse is determined depending on the duration of the welding and the supply of welding current Izg21 is resumed. The inverter welder, especially for spot resistance welding with a frequency of 10 kHz and higher, is equipped with the USZg welding machine control system (7) and the eczema detection system and includes the frequency converter section PCz (1), transformer welding machine Tr (2), high current rectifier P ( 3), welding electrodes (4). In the electrode clamping system, the electrode clamping force sensor CSDE (5) is connected to the AN analyzer input (6) and the analyzer output is connected to the USZg welding machine control system (7), which controls the frequency converter PCz (1).
