1. A multi point projection welding method comprising:
loading a component panel having one or more protrusions formed thereon onto a vehicle body panel such that the one or more protrusions of the component panel contacts the vehicle body panel at one or more welding positions;
applying pressure to the vehicle body panel at a first contact position using a vehicle body pressurizing tip and applying pressure to the component panel at a second contact position using a component pressurizing tip while the component panel and the vehicle body panel contact each other; and
supplying current to the vehicle body pressurizing tip and the component pressurizing tip such that the one or more protrusions of the component panel and a portion of the vehicle body panel contacting the one or more protrusions at one or more contact positions are welded onto each other while the vehicle body pressurizing tip and the component pressurizing tip apply pressure to the vehicle body panel and the component panel, respectively,
wherein at least one of the first contact position and the second contact position is different from each contact position of the one or more protrusions contacting the portion of the vehicle body panel, and
wherein the one or more welding positions are located between the first contact position and the second contact position.
