Technical requirements for intermediate frequency spot welder
The welding parts of all spot welders (including intermediate frequency inverter spot welders) are the core technical problems in the whole process of spot welders.The quality of welding operation will directly affect the final result
of the whole welding, which can not be ignored..So what should we pay attention to when welding parts of inverter spot welding machine? What are the technical requirements?Next, let the Hwashi editor take you into the details.
First of all, we know that when connecting steel plates of different thicknesses, if the thickness of the two sides of the steel plates varies too much, the cross-section after connection will change greatly, which will lead to serious stress concentration.Therefore, for important welded structures, such as pressure vessels, thin plates should be reduced.According to the relevant technical standards: when the thickness of the sheet is not more than 10 mm and the thickness difference between the two boards more than 3 mm, or when the thickness of the thin plate is greater than 10 mm and the thickness difference between the two plate by more than 30% of the plate thickness should be greater than the thickness of the sheet or more than 5 mm, thick plate edge should be sheet, sheet should be greater than or equal to the length of the sheet thickness difference of three times.
