The main characteristic of GALVANIZED STEEL is the zinc coating that protects and makes it more beautiful. First of all, zinc does not rust and protects the steel from the oxidation process when in contact with air. In second place, less steel is consumed and when it is used less raw material is needed. Stronger and safer structures are built using less metal. In addition, galvanizing does not require long-term care and maintenance.
Of this type of steel, it stands out that it prevents corrosion, for that reason galvanized steel sheets are usually applied for the elaboration of electrical appliances, construction materials or structures. Of this type of steel, we can point out that it prevents corrosion, for that reason galvanized steel sheets are usually applied for the elaboration of electrical appliances, construction materials or structures. LASERCOMERCIAL brings you a solution for welding galvanized steel: using the laser welding technique .
For years, many industries has had different options for welding between two or more pieces. Like different industries, over the years it has undergone changes which has allowed the emergence of new alternatives such as laser welding . Which allows you to do the same function, but with different processes and with better results. Even so, many people or companies for reasons of distrust to innovate do not know or are in doubt as to which alternative is the correct or the most appropriate. That is why we will start by talking about the old techniques or methods that can perform the same function as laser welding, but with some disadvantages. There are techniques such as spot welding or arc welding that are usually applied to this type of material.
This technique practically consists of heating one of the two parts to a temperature close to that of fusion and then applying pressure between them. This system works when the material is heated with electric current between two electrodes and it is these two that carry out the pressure of these two pieces. But during this process we can find the following inconveniences:
Fusion process whose function is the union of two or more metals forming the shape of an arc together with the electrode, hence the name. The pieces are placed at high temperatures through the use of a potential differential and intensity value of a determined electric current. As disadvantages when using arc welding we can highlight the following:
In summary, we can conclude that the welding of galvanized steel using old or traditional welding alternatives can become a problematic process. The zinc coating melts at 450ºC and in doing so generates gases that create bubbles that create porosities and incorrect welds in poor condition. It requires a treatment of the metal and an almost obligatory contribution of material for the welding to be in good condition.
That is why laser welding is used as a method to cover the disadvantages of spot welding since it is not necessary to consider the dispersion of electricity.
To solve these problems and many more adversities that traditional welding methods pose, there is laser welding and LC-WELD equipment . LaserComercial’s laser welding represents a great innovation in the metal sector as it speeds up and makes the process very profitable, as well as improving the quality of the welds, leaving a fine and aesthetic welding line .
Laser welding is a fast method and does not require a great deal of experience to be used. It gives incredible results even on those metals that, with traditional methods, are more difficult to weld.
