Types of Brazing Flux
Borax-Based Fluxes
Borax, or sodium borate, is a traditional flux component known for its effectiveness in dissolving metal oxides. Borax-based fluxes are commonly used in brazing ferrous and non-ferrous metals, excluding aluminum.
Fluoride-Containing Fluxes
These fluxes incorporate fluorides to enhance their activity, making them suitable for brazing metals with tenacious oxides, such as stainless steel and nickel alloys. However, they require careful handling due to their corrosive nature.
Phosphorus-Containing Fluxes
Phosphorus acts as a self-fluxing agent when brazing copper to copper, eliminating the need for additional flux. However, when joining copper to other metals, an external flux is necessary to ensure joint integrity.
Aluminum Brazing Fluxes
Specialized fluxes are formulated for aluminum brazing due to the metal's rapid oxidation and the stability of aluminum oxides. These fluxes often contain chlorides and fluorides to effectively remove aluminum oxide layers.
Types of Dotting Machine
Vibro Peen Marking Devices
These devices are versatile and capable of marking different metal materials. Vibro peen marking systems utilize a vibrating stylus made of carbide that helps create permanent, precise markings that ensure traceability and legibility.
Pneumatic Dot Peen Marking Devices
Pneumatic marking devices are used to mark metal surfaces or parts. As a result, pneumatic dot peen devices are best used in casting, stamping, forging, rolling mills and other applications. These devices create permanent marks that secure a product’s identity, which can help prevent theft in various industries.
Advantages of Dotting Machine
Versatility
A dot peen marking machine can be portable, which is ideal for marking large part batches, frames, or other large products. For marking and engraving small to medium-sized parts, the machine can be attached to a column base. This can be done quickly and efficiently, allowing you to integrate it into a line for mass production as well.
Longevity
This style of marking makes numerous impressions using a stylus to deform the material. The mark is permanent and will be readable for the life of the part. This method is increasingly popular for bicycles, aircraft parts, and VINs on vehicles.
Data Storage
Datamatrix has significant capacity allowing for up to 2335 alphanumeric or 3116 numeric characters in 1 cm² surface. This type of code also provides a reliable and readable mark, even with up to 20% deterioration.
The Role of Brazing Flux
Oxide Removal
Flux chemically reacts with existing oxides on the metal surfaces, dissolving them to expose clean metal.
Oxidation Prevention
By forming a protective barrier, flux prevents further oxidation during the heating process.
Enhanced Wetting
Flux promotes the smooth flow and adhesion of the filler metal to the base metals, ensuring a robust joint.
Brushing: Applying flux directly to the joint area using a brush ensures targeted coverage.
Dipping: Smaller components can be dipped into a flux solution for uniform application.
Pre-Mixed Paste: Some fluxes are available as pastes combined with filler metal powders, allowing for precise placement.
Ventilation: Ensure adequate ventilation in the workspace to avoid inhaling fumes generated during brazing.
Protective Equipment: Wear appropriate personal protective equipment (PPE), such as gloves and safety glasses, to prevent skin and eye contact.
Proper Storage: Store fluxes in labeled, sealed containers away from moisture and incompatiblesubstances.
Applications for Dotting Machine
Forging Industries
Forging industries utilize Dotting Machine machines to put identifying marks on different products, such as structural steel, iron castings and forged products that are sent away for heat treatment or finishing. Forging companies use dot peen marking as a backup method to transfer part numbers.
Rolling Industries
Rolling industries utilize Dotting Machine machines to place identification marks on rolled metal sheets. While other types of marking systems can be used in these industries, dot peen marking is the preferred method. These machines help rolling industries easily transfer information onto the product surface without leaving signs of impressions.
Casting Industries
You can use Dotting Machine machines in the casting industry to put identification marks on castings, which is ideal for making it easier to identify specific components during production cycles or marking components to prevent theft. Dot peen marking systems can draw part numbers or logos on castings.
Purchasing Industries
Dotting Machine places identifying markers on raw metal materials that are moved to factories from vendors and suppliers for additional processing. These markings assist manufacturers with delivering catalogs, receipts and purchase orders so they can look up orders and prevent errors.
Stamping Industries
The stamping industry uses many metal parts and metal-forming processes. In this industry, steel dies hit blanks repeatedly until you achieve your desired shape. Sometimes, these blanks are pressed from ingot or sheets at high pressures, which can cause them to have uneven markings or distortions.
