Product Description

Brazing
Brazing is the process of joining two pieces using heat and a filler material that melts at a temperature above **7 ºC (**0 ºF) and below the melting point of the parts to be brazen.
The filler material used in brazing varies depending on the parts being joined. The most commonly used alloys are phosphor copper, silver, nickel and cobalt, aluminium, silicon, copper, copper-zinc and magnesium.
The reason for this process between parts of the same or different materials is to create a permanent bond high strength, simplify mechanical operation and adopt simple production techniques, always compatible with the demands of mass production, among others.
There are different methods of heating for brazing, for example the flame, oven, infrared, laser and induction. Brazing by induction has a number of advantages over these other methods.
 Induction heating advantages:
Improved process efficiency
Fast and localized heat
Automated process
Temperature control
Energy saving
Less oxidation
Possibility of brazing in vacuum or atmosphere
Creation of clean joint, precise and controllable
Clean and technologies
The process eliminates the distortion and other undesirable metallurgical changes in different regions of the work pieces
Some of the industries related to this process are household, medicine, aerospace, railway and automotive.
Heating
Pre-heating
This is the heating used before processes like galvanizing lines, certain welding processes, deposits of some materials and cable extrusion among others.
Post-heating
This is the heating used afterwards processes such as cross-linking polymers, draining zinc, paint drying and curing resins and cable among others.
Heat staking
When a structural component is produced from a thermoplastic material, it is possible to heat a piece of metal to a temperature above the plastic flow point and insert it.
The process of joining metal to plastic requires a fast, precise and repeatable heating to prevent quality defects (melted or burnt plastic overflow).
To realize this process, several methods can be used, such as gas, electrical resistance or induction.
Induction heating advantages:
Improved process efficiency
Localized, constant and precise heating
Temperature control
Energy saving
Possibility of integration into production lines
Best quality and yield/performance
Pollution free, fast and secure technology
Improved working environment
Industries related to these processes are food industry, cable, shipbuilding and aerospace.
Welding
Welding is the process of joining two metals where the base material is elevated to a high temperature to exceed its melting point and in which, using its liquid state, are mixed to form a union of the fusion of all parties involved including a filler material if exists.
There are different forms of heating for welding, such as flame, contact at low or high frequency, TIG, MIG or MAG, and induction. However, all welding processes operate in very similar ways.
Given the characteristics of continuous process in tube production, induction welding presents a number of advantages over the other techniques already mentioned.
Induction heating advantages:
Energy saving
No physical contact and less maintenance.
Minimizes the time of heating. Therefore it reduce oxidation and decrease production time.
Easier cleaning processes afterwards
Reduces the heat affected area
Reduced risk causing a more pleasant work environment than conventional methods.
Possibility to automate welding processes which leads to an easier implementing and repetitive process.
A related industry to this process is tube and pipe.
