How to control the position of high frequency induction coil
How to Control the Position of High-frequency Induction Coil of High Frequency Straight Seam Welded: 1.The excitation frequency of the high-frequency straight seam welded pipe is inversely proportional to the square root of the capacitance and inductance in the excitation circuit, or to the square root of the voltage and current, and the magnitude of the excitation frequency can be changed by changing the capacitance, inductance or voltage in the circuit. to achieve the purpose of controlling the welding temperature. For mild steel, welding temperature control in 1250 ~ 1460 ℃, to meet the pipe wall thickness of 3 ~ 5mm penetration requirements. In addition, the welding temperature can also be achieved by adjusting the welding speed. 2,High-frequency induction coil should be close to squeeze roller position. If the induction coil is located farther away from the squeeze roller, the effective heating time is longer, the heat affected zone is wider, and the weld strength is de...
