Spot welding
Spot welding that securely joins any materials of any thickness
Spot welding is used on many parts of a vehicle body. The technique of spot welding is becoming more and more complex as cars now use high tensile materials. Keylex is especially proud of its technique of slag-free welding, which contributes to realizing a clean environment inside the plant.
In addition, we have adopted 20R electrodes, which eliminate the need for changes of welding guns, and to ensure the welding quality, we have developed tip monitors, which automatically monitor the dressing condition of electrode tips.
Resistance seam welding
Making fuel tank highly air-tight
We have been manufacturing steel fuel tank with the technique of resistance seam welding.
With the 3D seam welding technology, which synchronizes with robots and welding machines, we can provide high-quality products in high-speed such as saddle type 3D products required for FR and 4WD cars.
Laser welding
Laser welding that accomplishes innovation in production process
By applying the results of research and development in the remote laser welding, which has become increasingly popular for improving the rigidity of vehicle bodies, our innovative production technology has achieved shortening process time to 1/20 on the filler pipe which requires high air-tightness (compared to MIG brazing).
Laser cleaning
To resolve the joining defects
At the time when joints the different materials such as metal (steel, etc.) and
aluminum (self-piercing rivets, etc.), and locally removed the coated film on the
surface of materials.
Now, we are developing our technologies to resolve the joining defects that
occur during the assembling process.
Aluminum joining
Aluminum joining technology that achieves high quality of appearance
Aluminum requires more advanced technology compared to steel.
We are particular about appearance and working on developing and improving friction spot joining and arc welding technologies.
Friction spot joining
In addition to welding strength and quality stability, we have been developing welding tools internally and utilizing them for mass production to make welding appearance beautiful and car owners to be pleased.
MIG welding
We have realized MIG welding of aluminum, which is more difficult than that of steel, in an automated line using robots.
