Resistance welding

A welding method to connect by diverting an electric current to a base (copper pipes) which I want to weld with the resistance welding (ていこうようせつ), and producing a Joule heat, and dissolving the mother's body, and pressurizing it with it. The welding method that I applied this method to includes spot welding, seam welding.

I can express the heat capacity in the following expressions.

Caloric = 0.24I²Rt

The meaning of each value in a ceremony.

• I: Current value (unit ampere)
• R: Resistance level (unit ohm)
• t: The time when applied an electric current (unit second)
• Heat capacity: Heat capacity (expression 0.24 disappears a unit calorie when I measure a unit in Joule, and, in the right side, it is merely in I²Rt.) to occur
