Cooking Pots

An application of brazing in the food industry is the cooking pots. The cooking pots made of stainless steel are provided with an aluminum compensating base for uniform heating. The base part is brazed with the stainless steel part. Brazing provides leak proof, clean and smoother joints.


Brazing Process
The most suitable brazing process for the cooking pots is induction brazing. Other useful processes are flame brazing and furnace brazing.

Brazing Alloys
Aluminum based brazing alloys are used for brazing the base of cooking pots. The constituent elements are :

• Major Constituents: Aluminum and Silicon
• Other Constituents: Iron, Copper, Manganese, Magnesium, Zinc, Titanium
• These type of alloys are good for brazing of aluminum and low alloyed aluminum alloys. It is also good for brazing aluminum to stainless steel. It is also applied in brazing of sandwich bottoms, heating elements and radiators.

Spectacle Frames

Stainless steel spectacle frames are another example of brazing applications. The frames of stainless steel spectacles are very slim and thin so the joining of different component require a lot of attention and care.


Brazing Process
Induction brazing is considered the most suitable brazing process for the joining of these frames. It provide clean, smooth and strong joints. Other brazing methods like flame brazing can also be used.

Brazing Alloys
Silver brazing alloys are best for brazing the stainless steel spectacle frames. Silver is the primary constituent of these alloys, constituting more than 60% by weight. Copper is the second most major constituents with almost 30% by weight. Tin is also used constituting around 10%. Other elements present in lesser amount are aluminum, bismuth, cadmium, phosphorous, lead and silicon.

Alloys having these composition are suitable for brazing any steels, copper and copper based alloys and also for nickel and nickel based alloys. These alloys are well suited for brazing under protective atmosphere or under vacuum.

Bracket

Brazing is used in the joining of bracket on a mouth brace. It involves an aluminum oxide stainless steel brazed connection.


Brazing Process
Furnace brazing is used for its brazing. Pure argon atmosphere is used during the brazing.

Brazing Alloys
Silver brazing alloys are mostly used for this purpose. Its main constituents are silver and titanium is also present in it. The other constituents present in lesser extents are aluminum, cadmium, bismuth, phosphorous and silicon.

Ice Cream Scoop

Brazing has also found applications in the food industry. One of its application is ice cream scoop. The ice cream scoops are made of stainless steel and brass. Among all other metal joining processes, brazing provides extremely smoother, clean and strong joints so they are preferred over others processes.


Brazing Process
Flame brazing or induction brazing are the two most suitable brazing processes for joining the ice cream scoops. Either of them can be chosen according to choice and ease of operation.

Brazing Alloys
Silver brazing alloys are used for brazing the stainless steel/ brass ice cream scoops. Silver, copper, zinc and tin are the main constituents of these brazing alloys. Aluminum, cadmium, bismuth, phosphorous. Lead and silicon are also present in lesser amount.

These silver based brazing alloys have excellent flow characteristics. They can be used for brazing any steels, copper and copper based alloys as well as for nickel and nickel based alloys. Its typical application are found in automotive and electrical industry.

Surgical Instruments

The different instruments used in surgery are also an important example of application of brazing. Various surgical instruments, such as scissors, forceps, knives, scalpels, dissecting pins, cell scraper, etc are manufactures using the brazing process. Most of these instruments are made of different types of steel, such as stainless steel, carbide steel, mild steel, etc.





Brazing Alloys
Since most of the surgical instruments are made of some kind of steel so silver brazing alloys are most suitable for them. Silver is the primary constituent element in these alloys and occupy more then 60% by weight. Copper is the second main constituent element after silver, occupying almost 25% by weight. Other important constituents are manganese, nickel, and indium. Smaller amounts of aluminum, bismuth, cadmium, phosphorous, lead, and tin are also present.

Brazing Process
Induction heating is mostly used for brazing the surgical instrument. The most important factors to be kept in mind during the brazing of surgical instruments are cleanliness, smooth joints, and strength. Induction brazing provides all these features so it widely accepted. Other brazing methods, which are also used are flame brazing, furnace brazing and torch brazing.

Pots with Spouts

Another application of brazing in the food industry is the pots with spouts. They are made of stainless steel. The spout is a separate part and brazed with the main pot.







Brazing Process
Flame brazing is used for the brazing of pots with spouts.

Brazing Alloys
Silver based brazing alloys are considered the best for brazing the stainless steel pots. Its constituents are as follows:

• Major Constituents: Silver, Copper, Tin
• Other Constituents: Aluminum, Bismuth, Cadmium, Phosphorous, Lead, Silicon
• These alloys can be used for brazing any type of steels, copper and copper based alloys, nickel and nickel based alloys. It can be used for brazing with flame or induction brazing procedures.

Distributors

Copper pipe distributors are another good example of brazing application. In the distributors a lot of copper to copper joints are needed. Brazing provides an efficient method of joining.


Brazing Process
For the brazing of copper pipe distributors, flame brazing is the most suitable process. Flame brazing provides clean, smooth and uniform joints.

Brazing Alloy
Since the metals to be joined are copper so copper based brazing alloys are the best for joining them. The constituents are:

• Major Constituents: Copper, Silver, Phosphorous
• Other Constituents: Aluminum, Bismuth, Cadmium, Lead, Zinc.

Copper Pipe Connections

Brazing is considered the most efficient metal joining process because of its excellent joining properties. It provide clean, smooth and uniform joints. The necessity of these type of joints are high in demand in a number of industries. A large number of metallic products require uniform heating and bondings, which are fulfilled by the brazing processes.


Brazing of copper pipes is such an example of brazing applications. Copper pipes and tubes are used in different field and sectors. Brazing provides the reliable joints, which are gas-tight and pressure-tight.

Brazing Alloys
Copper based brazing alloys are used for the brazing of copper pipes. They are suitable for this purpose. Apart from copper other main constituents are silver and phosphorous. Certain other elements are also present in these alloys though to a lesser extent are aluminum, bismuth, cadmium, lead, zinc. Due to the presence of phosphorous in the alloys there is no need of additional flux.
