Method for welding cutter head by dropping copper liquid medicine

According to Baidu's procurement, the following are the methods for dropping the liquid medicine from the brazing cutter head:

1. Use solvents to remove copper solder joints: If you need to remove copper solder joints, you can try to use the following solvents:

1. sodium hydroxide solution: sodium hydroxide solution can be used to remove copper solder joints, but its strength is high, so attention should be paid to safety when using it. Please wear gloves and protective glasses before use, and soak the solder joint in sodium hydroxide solution. After waiting for a period of time, the solder joint will loosen and fall off.

2. Potassium hydroxide solution: Potassium hydroxide solution can also be used to remove copper solder joints. Similar to sodium hydroxide solution, you should also pay attention to safety when using it. Soak the solder joint in potassium hydroxide solution, wait for a period of time, and the solder joint will loosen and fall off.

3. Chlorine-containing solution: Chlorine-containing solution can also be used to remove copper solder joints. Soak the solder joint in a solution containing chloride, and after waiting for a period of time, the solder joint will loosen and fall off. Please pay attention to keep ventilation when using, so as not to produce harmful gases.

Second, other physical methods to remove copper solder joints:

Besides using solvents, you can also try the following physical methods:

1. Knock with a copper hammer: put the copper hammer on the solder joint, tap the copper hammer with a hammer, and knock the solder joint loose and then fall off.

2. Use the electrode holder: The electrode holder can cut off and fall off the solder joint, but it should be used safely.

Generally speaking, if the solder joint of copper needs to be removed, solvent is a common method, but it is not safe and needs to be used with extra care. If the solder joint is firm, you can try other physical methods. I hope these methods can solve related problems for you.
