When Brazing copper to copper flux is normally not needed When brazing steel or copper based alloys then the flux is used to help the wetting action (Better flow of the brazing alloy) and to prevent oxidation A typical rod would be Union Carbide 25 M or check out the AWS booklet
What else can I help you with?
Are soldering and brazing fluxes the same?
No, soldering and brazing fluxes are not the same. Soldering fluxes are designed to remove oxides from the metal surfaces being joined during soldering, while brazing fluxes are formulated to clean the joint and promote wetting for the filler metal in brazing processes. Additionally, brazing fluxes can handle higher temperatures compared to soldering fluxes.
What transportation consideration is applied during offensive operation?
Extended supply lines increase delivery and turn around times
Why is extraction a very important part of the brazing hearth?
Extraction is crucial in the brazing hearth because it removes harmful fumes, smoke, and gases generated during the brazing process, ensuring a safe working environment for operators. Effective extraction also helps maintain the quality of the brazed joints by preventing contamination from airborne particles. Additionally, proper ventilation aids in temperature control, which is essential for achieving optimal brazing results. Overall, extraction systems contribute to both safety and product integrity in brazing operations.
Can you remove brazing from steel?
No, once steel has been brazed, the brazed joint cannot be removed without damaging the base metal. The brazing material becomes metallurgically bonded to the steel during the brazing process. If the brazed joint needs to be removed, the only way is to cut or grind it off, which will alter the original piece.
Why is a lap joint better than a butt joint for brazing purposes?
A lap joint is generally better than a butt joint for brazing because it provides a larger surface area for the brazing material to adhere to, enhancing the strength of the joint. Additionally, the overlapping design allows for better alignment of the parts and can help to minimize gaps, which is crucial for achieving a strong, leak-proof bond. This configuration also allows for more effective heat distribution during the brazing process.

Your consultants are asking you to pass nitrogen through copper pipes while brazing to prevent oxidation inside the pipes. These pipes are for refrigerant. Is this a regular practice?
AnswerPumping nitrogen through refrigerant piping during brazing is an excellent practice. The reason is that nitrogen helps to prevent the buildup of oxide scale on the inside of the pipes during the brazing process. Refrigerant is a natural cleaning agent, and as it is being pumped through the pipes it will pick up the scale and contaminate the refrigerant. It is possible that this will damage to the compressor.
Drugs are applied on the skin during?
Drugs are applied to the skin during inflammation or infection.
Time critical ORM is used?
Used when there is little time, little complexity, or low risk. Often used during the execution phase of an operation where an unplanned change occurs and must be managed. It's easily applied to off-duty situations.
How many soldiers were injured during Operation Barbarossa?
3,542,837 Soldiers were wounded during Operation Barbarossa.
What materials are used in brazing?
Brazing typically involves the use of filler metals such as silver, copper, aluminum, or nickel alloys, which have a melting point above 450°C (842°F). The base metals being joined can include steel, copper, brass, and aluminum. Flux materials are often used to prevent oxidation and improve the flow of the filler metal during the process. Additionally, a heat source, such as a torch or furnace, is required to achieve the necessary temperatures for brazing.
Does a diesel engine produce carbon monoxide during operation?
Yes, a diesel engine does produce carbon monoxide during operation.
