Passivating Stainless Steel

Passivation by definition of the ASTM A 967, is taking out the surface iron in a metal with an acid solution. In addition, passivation is also process of making something no longer chemically active, it is instead passive. The result of this is the passive surfaces of the material will become resistant to many reactions, even corrosion.

Types of Metals

Many metals like titanium and aluminum are for the most part able to pacify themselves. The oxygen in the air reacts to the atoms in the metals, creating a bed of oxide. For these certain metals, iron is left behind on the surfaces.

So, for these particular metals in order to pacify them, the iron must be removed from the surface. To do this, a simple acid solution is applied to the metal.

passivation lab

In addition, stainless metals as well as corrosion resilient metals can also generate rust as a result of the steel alloys they contain. In these types of metals which include, nickel and chromium, they must be left to react to the oxygen in the air in order of the oxide layer to form.

Passivation Layer

This layer will offer another level of protection from the rust forming on the corrosion resilient and stainless metal surfaces. Other parts of the alloys in these specific metals can linger behind on the upper layer of the repressed steel. This is an essential component in protecting the remaining steel from corrosion.

This process can be ruined through the different mechanical processes the steel can go through, and once this happens, the outer layer will be susceptible to rusting once again. This is where the passivation process comes in.

Passivation Process

During this process in the ending step of making stainless steels, the surface iron would be removed rendering the reaming steel to be rust resistant. On the contrary, any exposure to chlorides, will cause chemical damage to the metal’s passive layer. Ocean salt water, bleach and salt are very damaging to the stainless steel.

The preferred acid to use for eliminating the iron in the metal is citric acid. This is due to the overwhelming safety precautions that citric acid poses as opposed to nitric acid. The atomic level of nitric acid kills the iron in the metal, but due to it’s acidity it also harms the other components in the alloy as well.


While getting rid of all of these elements that the nitric acid has removed as well, the waste product from it becomes toxic, causing danger to those who handle it. On the other hand, citric acid safely removes only the iron on the metal.


The only draw back is the metals contain lots of carbon or sulfur. These parts will remain on the surface of the metal posing as a sticky substance for sulfide and the carbon turns dark, mimicking the look of rust. In order to fix these problems, just remove the sulfur and the carbon with an alkaline mixture beforehand, and then you may remove the iron with the citric acid.

Blue colored or straw colored oxides can deposit themselves on stainless steel as a result of soldering or welding. A simple fix is to clean it with a scrubbing cleanser before using it.

5 Things You Need to Tell an RF Welding Professional for an Assessment

If you’re considering radio frequency welding services for your product, you should make sure it’s the right heat sealing process for you by taking it in for assessment at the hands of an RF welding expert.

To get an accurate assessment, there are certain details you should provide for an industry expert.

What is the Product’s Intended Function?medical RF welding

The very first thing you should tell an RF welding expert is the functionality of your product. What is it designed to do?

Radio frequency welding is strong, but if a product is intended to contain compressed air under high pressure over 30 psi, RF welding may not be the best sealing option. Heavier fabrics will need to be used for products designed to withstand abrasion as well, and a specific rating may be required for materials in certain industries with strict standards.

What is the Size of the Product?

Another important factor that will determine if your product is right for RF welding is the size of the product being welded. The larger the product, the more difficult it will be to successfully form a strong seal.

If your product is too large, it may require a much more extensive welding service than radio frequency welding.

What is the Configuration?

RF welding is designed to handle two-dimensional product configurations, whereas three-dimensional configurations may require more complex sealing methods, depending on the materials.

Make sure your product configurations are made with RF-sensitive materials such as vinyl prior to considering this service on three-dimensional products.

What is the Application?

The application of your product plays a huge part in determining whether or not RF welding is the appropriate sealing method. Again, this ties into the materials required by the specific industry in which the product will be used.

Are Any Drawings Available?

One last item that can significantly help with the RF welding process is a drawing or series of drawings that detail your product layout. This could help the expert decide on the best way to approach the RF welding process. CAD type drawings are the most ideal.

Many places accept other types of drawings as well, though, so CAD drawings aren’t always necessary. Some places accept DXF or DWG files, for example.

If you keep these five major factors in mind when considering radio frequency welding for your product, an expert will not only be able to determine whether the process is right for your product or not, but also be able to suggest another more suitable sealing process.

Ultrasonic Welding Technique

Ultrasonic welding involves the use of high frequency sound energy to soften or melt the thermoplastic at the joint. Parts to be joined are held together under pressure and are then subjected to ultrasonic vibrations usually at a frequency of 20, 30 or 40kHz.

The ability to weld a component successfully is governed by the design of the equipment, the mechanical properties of the material to be welded and the design of the components.welding info

Since ultrasonic welding is very fast (weld times are typically less than 1 second) and easily automated, it is a widely used technique.

In order to guarantee the successful welding of any parts, careful design of components and fixtures is required and for this reason the technique is best suited for mass production.

Ultrasonic Welders

An ultrasonic welding machine consists of four main components: a power supply, a converter, an amplitude modifying device (commonly called a Booster) and an acoustic tool known as the horn (or sonotrode). The power supply changes mains electricity at a frequency of 50-60Hz, into a high frequency electrical supply operating at 20, 30 or 40kHz.

This electrical energy is supplied to the converter. Within the converter, discs of piezoelectric material are sandwiched between two metal sections. The converter changes the electrical energy into mechanical vibratory energy at ultrasonic frequencies.

The Process

The vibratory energy is then transmitted through the booster, which increases the amplitude of the sound wave. The sound waves are then transmitted to the horn. The horn is an acoustic tool that transfers the vibratory energy directly to the parts being assembled, and it also applies a welding pressure.

The vibrations are transmitted through the workpiece to the joint area. Here the vibratory energy is converted to heat through friction – this then softens or melts the thermoplastic, and joins the parts together.

Plastic Joining

Benefits of the process include: energy efficiency, high productivity with low costs and ease of automated assembly line production. The main limitation of the process is that the maximum component length that can be welded by a single horn is approximately 250 mm.

This is due to limitations in the power output capability of a single transducer, the inability of the horns to transmit very high power, and amplitude control difficulties due to the fact that joints of this length are comparable to the wavelength of the ultrasound. Ultrasonic vibratory energy is used in several distinct assembly and finishing techniques as described below:


The process of generating melt at the mating surfaces of two thermoplastic parts. When ultrasonic vibrations stop, the molten material solidifies and a weld is achieved. The resultant joint strength approaches that of the parent material; with proper part and joint design, hermetic seals are possible. Ultrasonic welding allows fast, clean assembly without the use of consumables.


The process of melting and reforming a thermoplastic stud to mechanically lock a dissimilar material in place. Short cycle times, tight assemblies, good appearance of final assembly, and elimination of consumables are possible with this technique.


Embedding a metal component (such as a threaded insert) in a preformed hole in a thermoplastic part. High strength, reduced moulding cycles and rapid installation with no stress build-up are some of the advantages.


Mechanically capturing another component of an assembly by ultrasonically melting and reforming a ridge of plastic or reforming plastic tubing or other extruded parts. Advantages of this method include speed of processing, less stress build-up, good appearance, and the ability to overcome material memory.

Spot Welding

An assembly technique for joining two thermoplastic components at localised points without the necessity for preformed holes or an energy director. Spot welding produces a strong structural weld and is particularly suitable for large parts, sheets of extruded or cast thermoplastic, and parts with complicated geometry and hard-to-reach joining surfaces.


The use of ultrasonic energy to slit and edge-seal knitted, woven and non-woven thermoplastic materials. Smooth, sealed edges that will not unravel are possible with this method. There is no “bead” or build-up of thickness on the slit edge to add bulk to rolled materials.

Textile/Film Sealing

The use of ultrasonic energy to join thin thermoplastic materials. Clear, pressure-tight seals in films, and neat, localised welds in textiles may be accomplished. Simultaneous cutting and sealing is also possible. A variety of patterned anvils are available to provide decorative and functional “stitch” patterns.

Typical Ultrasonic Welding Applications

Ultrasonic assembly is the method of choice for many applications in the automotive, appliance, medical, textile, packaging, toy and electronics markets, among others. The basic advantages of ultrasonic assembly – fast, strong, clean and reliable welds – are common to all markets. However, each market has specialised needs that they rely on ultrasonic assembly to meet.

Appliance In this high-volume market, hermeticity, strength and also cosmetic appearance are important. Applications include: steam iron, pump housing, vacuum cleaner wand, and dishwasher spray arm.
Automotive Hermetic seals in applications such as lenses, filters and valves. Other applications include: glove box door, instrument cluster, air diverter and mass airflow sensor.
Business “Clean” assemblies with reduced particulate matter are produced on information storage discs. Other applications include the assembly for ribbon cartridges, and audio and video cassettes.
Consumer Precision radio frequency welding, staking and forming operations are used in the manufacture of the Swatch®.
Electrical Multiple staking and inserting applications are often automated for high-volume production requirements with consistent reliability. Applications include: terminal blocks, connectors, switches (e.g. toggle, dip, rotary quick and diaphragm), and bobbin assemblies.
Medical Non-contamination and the ability to be operated in a clean room are as important as the strength of the weld. Reliable, repeatable assemblies for critical life-support devices are produced with new capabilities in process control. Applications include: arterial filter, cardiometry reservoir, blood/gas filter, face mask and IV spike/filter.
Packaging From aseptic packages to toothpaste tubes, the ability of ultrasonic assembly to seal through product contamination in the joint area is a major advantage. In addition to good cosmetic appearance, ultrasonic assembly provides tamper-evident seals for blister packs. Applications include: condiment dispenser, blister package, juice pouch, juice carton and plastic coated paper cups.
Toys In this highly competitive industry, the elimination of adhesives, screws and solvents, or other consumables is a bonus added to strong, safe, flash-free assemblies.

How Exactly Does Radio Frequency Sealing Work?

The radio frequency sealing process is not new, with manufacturers having used the process for over 60 years in order to create strong, durable products. However, in spite of its age, this technology is as reliable as it ever was. The process is also referred to as RF welding/sealing, dielectric sealing or high frequency welding.

How the Process Creates Strong Seals

Radio frequency sealing uses electromagnetic waves to heat two similar or dissimilar materials, which excites their polar molecules and causes them to rearrange, fusing together the two melted materials as heat is generated. The materials used in the process must have a polar molecular structure in order for it to work, which includes common plastics like polyurethane and PVC, as well as other polymers such as Nylon, EVA, PET and several ABS plastics.


The equipment involved in the process includes a table press and tooling dies. The two material surfaces are held on the table press that puts pressure on them. Then the electromagnetic waves travel through the narrow space between the die and table where sealing occurs. The combination of pressure and generated heat causes the materials to then melt and fuse together, forming a seal that is ultimately as strong or even stronger than the original materials.

The presence of a buffer is needed to facilitate the process, as it provides some electrical resistance to the radio frequency energy and prevents the process from putting holes in the material.

Fabricating Tough Plastic Products

Many industries rely on radio frequency sealing because of the strength of the bond the process creates. The medical, military and government industries use this process in many of their products, along with many other industries. Inflatable bladders for liquid containment and industrial curtain walls are simply a couple of the important products that use RF welding in their construction.
