Induction welding is a technology that uses electromagnetic induction to heat the workpiece.
An induction coil generates a high-frequency electromagnetic field. In conductive materials, this electromagnetic field causes resistive heating induced by the currents, in order to obtain fast and precise welded joints.
Induction welding or brazing is an industrial process used to weld ferromagnetic or electrically conductive components by inducing eddy currents in the material through the application of external magnetic fields. It is a quick, effective, precise, repeatable, non-contact method. A range of temperatures can be used, from 100°C to 3000°C (212-5432°F), for brief or extended heating periods. A study of the placing, construction using aluminum oxidizes, and forced cooling with chillers are required to run continuous welding cycles at a high frequency. Our expertise enables us to integrate induction welding systems into our assembly and testing lines.

Laser welding is an industrial process used to weld two polymer or metal components using the ability of lasers to deliver enormous quantities of concentrated energy to a point in a very short time (nanoseconds). This technology provides a high power density, which results in small heated areas with rapid heating and cooling. The size of the laser beam can vary from 0.2 mm to 13 mm (0.008 - 0.5"). The smaller dimensions are used for welding metals with high melting points. The depth of penetration is proportional to the power supplied, but it also depends on the position of the focal point: penetration is the greatest when the focal point is close to the surface of the piece to weld. An imbalance in the focal point instead makes certain special types of heating possible that are required to execute specific tinplate welding applications.
This type of technology yields enormous advantages: fast working speeds, minimal heat input, excellent solder appearance, preset penetration depth, and extremely high mechanical solder strength.
The process is also excellent for brazing. Camas's expertise enables us to integrate laser welding systems into our assembly and testing lines.

Ultrasonic welding is an industrial process used to weld thermoplastic materials. The edges are fitted between a fixed-shape mold (anvil) and a sonotrode, which creates ultrasonic vibrations and is connected to a transducer.
Through molecular vibrations created by ultrasound frequencies, heat is generated to melt the material and achieve an excellent weld. The shape of the welded joint is crucial. Its purpose is to concentrate the energy in order to allow for a very rapid ultrasonic welding cycle. Size and shape are adjusted depending on the application and material to join. If the welding joint is less than 6mm (0.23") from the area that contacts the sonotrode, it is called near-field welding; when farther away it is referred to as far-field welding.
Since the project is not reversible, this technology provides permanent assembled systems.
This makes it the ideal technique for commonly used disposable products or single-use item, e.g. in the biomedical field. Our expertise enables us to integrate ultrasonic welding systems into our assembly and testing lines.

Hot plate welding is ideal for assembling injection, rotation, blown, extruded, and vacuum molded pieces. A simple and intuitive principle makes it possible to execute easy, inexpensive, consistent, and completely waterproof welds with impressive mechanical strength. Thermoplastics are melted through direct contact with a heated plate and electronically regulated temperature. One of the essential parameters is the pressure applied when welding the thermoplastics, along with the correct temperature setting. A hot plate shaped to replicate the geometry of the two parts to weld is placed between the two parts. The two opposing sides of the press push the two parts against the hot plate until the heat softens the surfaces, reaching the melting point of the plastic.
When this point is reached, the hot plate is removed and the two parts are pressed together until the weld cools and solidifies, creating a permanent joint. The pressure applied when welding thermoplastics is one of the fundamental parameters, along with the correct temperature setting, which ranges from 250 and 350°C (482-662°F). The pieces to be assembled are held in their respective placings and the hot plate welding cycle runs automatically. It is managed by setting the heating and cooling times.

TIG (Tungsten Inert Gas) or GTAW (Gas Tungsten Arc Welding) is an arc welding process that uses a non-consumable tungsten electrode protected by inert gas. The process can be performed with or without a filler metal. It is based on a torch fitted with a tungsten electrode around which the shielding gas flows. This gas is directed to the weld puddle through a ceramic outlet. The torch moves weld puddle as it travels along the joint, and if filler metal is needed, the rod of filler material is moved at the same time to keep its tip constantly within the arc, and thus within the protection of the gas. TIG welding is especially well suited when very thin pieces are to be welded, even as thin as tenths of a millimeter (0.004"). However, it cannot weld pieces thicker than a few millimeters (0.04", 2-3 mm or 0.078-0.11", for steels) with a single pass. Therefore, in general, it is not used for pieces thicker than 5-6 mm (0.19-0,23"). Because of its low productivity, it is often used to make the first pass on a weld. The filling is performed later with more efficient processes. Due to its characteristics, the process can be used in any position, for continuous welds or spot welding. This process is not recommended in open areas, because even a light breeze can disperse the shielding gas.
