The invention relates to a cold-rolled strip
welding technology method. A
welding framework drives an upper
welding wheel, a lower welding wheel, an upper
tempering wheel and a lower
tempering wheel to walk forwards; the instant the upper and the lower welding wheels are in contact with a
steel belt, controlled
silicon is closed through a trigger circuit, an original edge of a welding
transformer is powered on, a loop of an auxiliary edge of the welding
transformer is closed, The current flows through the
steel belt to act to generate heat through the resistance of the
steel belt, and when the heat is continuously accumulated to enable
metal on the welding portions to be combined through fusing; when the welding wheels separate away from the steel belt, welding is stopped; when the fire retuning wheels separate away from the steel belt,
tempering is stopped, and the upper welding wheel and the upper tempering are lifted; the welding framework is decelerated and stopped; the welding framework returns at a high speed to walk to the deceleration position to decelerate to return to the original position, and the
welding process is over; as shown in the attached chart 2, the
resistor is a sucking
resistor and equivalently serves as a load to have the buffering effect; the resistance-
capacitance circuit is resistance-
capacitance sucking protection controlled
silicon; a mutual
inductor compensates for sampled signals.
