Is welding harmful to health in electronics factory?

Tin welding is actually lead-tin welding. There is some volatilization during welding. If preventive measures are not taken, it will be inhaled and deposited in the body, which will do great harm to the body.

After lead enters the human body, except a part of it is excreted through feces and sweat, the rest dissolves into the blood after several hours, which hinders the synthesis of blood, leading to anemia, headache, dizziness, fatigue, constipation and limb pain. Some symptoms such as metallic taste in the mouth, arteriosclerosis, peptic ulcer and fundus hemorrhage are also related to lead pollution.

Precautions:

1. Try to use low temperature welding: high temperature will accelerate the oxidation of the welding head and reduce its life. If the welding head temperature exceeds 470℃, the oxidation rate is twice that of 380℃ ..

2. Don't apply too much pressure: Don't apply too much pressure when welding, otherwise the welding head will be damaged and deformed. As long as the welding head can fully contact the solder joint, heat can be transferred. In addition, the selection of suitable welding head is also helpful to heat transfer.

3. Always keep the welding head tinned: This can reduce the chance of welding head oxidation and make the welding head more durable. After use, the temperature of welding head should be slightly lowered before adding new solder, so that the tin plating layer has better oxidation resistance.
