What are the optimal process parameters for resistance welding of SPCC boards?
A: A welding current range of 8-12kA and an electrode pressure maintained at 2-4kN can yield qualified weld points with a diameter of 4-6mm.
Why does spatter occur excessively during SPCC board welding?
A: This is often due to excessive welding current, insufficient electrode pressure, or impurities such as oil or rust on the board surface, affecting the stability of the welding current and the state of the molten pool.
How to avoid porosity defects during SPCC board welding?
A: Clean the board surface of oil and rust before welding; select appropriate welding parameters and avoid excessive welding speed; ensure a stable supply of shielding gas.
What is the minimum bending radius of an SPCC board?
A: The minimum bending radius can reach 0.5 times the board thickness. Its excellent bending performance makes it suitable for various bending processing scenarios.
What is the ultimate draw coefficient of an SPCC board?
A: The ultimate draw coefficient it can withstand reaches 0.55. This characteristic allows it to meet most drawing and forming processing requirements.
