The spot weldability and the strength of singlespot-welded joint of a chinese steel WP 370 were investigated, and the effects of welding parameters on it were also tested.
The calculation of spotwelding current is determined by the way of point-by-point integration, the software and hardware system is constituted based on 80c196kc single chip computer.
This topic carries on the constant current control to the resistance spotwelding process using a system of single chip computer, whose core has used the C8051F005.
