What are the hazards of soldering for girls

Solder is a material frequently used in welding. Now many girls are also doing this kind of work. Here we want to remind everyone that although solder is a material, some smells and fumes produced during the welding process are a great threat to girls' health. Girls are not suitable for jobs like soldering, which may lead to anemia or dizziness. Learn more about the dangers of soldering for girls.

The first harm of soldering

Tin soldering is actually lead-tin soldering. During the welding process, a certain amount of volatilization will occur. If we are not careful, it will be inhaled into our body and will be deposited in our body, causing great harm to our body. After lead enters the human body, except for some excretion through feces and sweat, the rest will dissolve into the blood after a few hours, hindering blood synthesis, leading to anemia, headache, dizziness, fatigue, drowsiness, constipation and limb pain, etc. Some people have a metallic taste in the mouth, and symptoms such as arteriosclerosis, gastrointestinal ulcers and fundus hemorrhage are also related to lead pollution. Children suffering from lead poisoning may experience developmental delay, loss of appetite, difficulty walking, constipation, and insomnia; if they are elementary school students, they may also suffer from hyperactivity, hearing impairment, inattention, and mental retardation. This is because after lead enters the human body, it invades the brain's nerve tissue through the blood, causing insufficient supply of nutrients and oxygen, resulting in damage to brain tissue. In severe cases, it may lead to lifelong disability. So we should have good ventilation equipment when welding. To ensure our own safety.

Second soldering brief introduction

Solder materials are indispensable in the production and maintenance work of the electronics industry. Generally speaking, commonly used solder materials include tin-lead alloy solder, antimony-added solder, cadmium-added solder, silver-added solder, and copper-added solder.

The wire solder used in standard soldering operations is called rosin core solder wire or solder wire. Flux is added to the solder. This flux is composed of rosin and a small amount of activator.

The temperature setting during welding operation is very important. The most suitable temperature for welding operations is the melting point of the solder used + 50 degrees. The set temperature of the soldering iron tip should be increased by 100 degrees on the basis of the above temperature due to the size of the welding part, the power and performance of the electric soldering iron, the type of solder and the wire type.

The main solder products are divided into three categories: solder wire, solder bar, and solder paste. Applicable to various electronic welding, suitable for manual welding, wave soldering, reflow soldering and other processes.

The smoke produced by solder wire during welding is caused by the gasification of the flux inside the solder wire when it meets the high-temperature soldering iron. Friends who do this kind of work must ensure a good ventilation environment to ensure their health.
