What is high-frequency welding machine?
A high-frequency welding machine is a machine that uses high-frequency electric current to produce resistance heat on the contact surface of the workpiece, and applies pressure (or no pressure) to make the metal of the workpiece form a connection.
Unlike other welding machines, the function and purpose of high-frequency welding machines are not just for welding. high-frequency welding machines can be used for various other processes such as heat penetration, melting, and heat treatment. Welding is just one of its many uses.
Effects of high-frequency welding machine on the body
Actually, any AC circuit will emit electromagnetic energy with the same frequency as the AC frequency in the surrounding space, forming an alternating frequency electromagnetic field. When the frequency of the AC current reaches more than 100,000 times per second, a high-frequency electric field and magnetic field will be produced in the surrounding area, which is called a high-frequency electromagnetic field. Occupations that come into contact with high-frequency electromagnetic fields include radio communication, high-frequency heating (such as high-frequency welding and cutting), and the use of high-frequency medical equipment. Under certain levels of radiation over time, it can cause harm to human health.
The harm that the high-frequency electromagnetic field of high-frequency welding machines causes to the human body mainly occurs through two pathways: one directly affects the central nervous system or cell biological membrane. The symptoms of varying degrees of neurosis include general fatigue, easy tiredness, dizziness, headaches, chest tightness, palpitations, poor sleep, nightmares, memory loss, sweating, hair loss, etc. Most patients recover their health after receiving symptomatic treatment and ceasing exposure. The other pathway directly radiates human tissue, causing it to heat up and causing damage. This situation is extremely rare.
It is very harmful to patients with hypertension. For patients with sudden dizziness, it can cause dizziness and even coma. It is generally not recommended to use high-frequency equipment.
It is particularly serious for patients with heart disease. Patients should not be near high-frequency welding machines, and it may cause sudden death if the situation is severe.
Normal employees cannot work in a high-frequency environment for a long time. Generally, the working life limit is 7-10 years.
It has adverse effects on people's visual system. Since the eyes are the organs that are sensitive to electromagnetic radiation in the human body, excessive electromagnetic radiation can also affect the visual system. The main manifestations are decreased vision and cataracts.
