If you want to weld or connect two materials with a diameter less than a one-tenth millimeter, the best method is the so-called dot or point welding. This type of welding is very similar to the one used in welding tubes; however, point or dot welding utilized a laser to ensure that the small threads of materials are seamlessly joined.
While it is true that traditional welding has long been used to weld gold, copper, and tin, this method is incapable of joining materials with a diameter equals to one-tenth of a millimeter. But, if you really want to join different materials with a diameter equals to one-tenth of a millimeter, you must integrate the laser technology in the welding process.
Another setback of using traditional welding is that it cannot weld copper to stainless steel or copper to titanium. Much more if you want to join into titanium or tin to stainless steel. In other words, it is tough to weld two different metals. The only way to weld dissimilar metals such as steel and copper is by integrating laser technology to the dot welding.
With the power of the laser, you can easily weld two dissimilar metals, even if they have a diameter as small as one-tenth of a millimeter, in no time. However, you must be very careful about doing dot laser welding. Always remember that dot laser welding deals on the metal’s micro coil; hence, it must always be précised. The dot laser welding needs to finely overlap the micro coils of the subject materials (materials to be joined) even if their respective diameters are as minute as one-tenth of a millimeter. Aside from making sure that the micro-coil of the metals are finely overlapped, the dot laser welding must also draw the micro-coil very near to each other to ensure that there will be no welding gap.
Due to the delicateness and sensitivity of joining micro coil of different metals, dot laser welding is definitely not a no-brainer. It takes thorough training to perfect this process. In fact, dot laser welding has a narrow tolerance and requires a very high temperature. And since the dot laser welding is considered as a micro-welding technique, the use of a microscope is recommended in carrying out this procedure. The use of a microscope will ensure that the laser will perfectly hit the intended welding spots.
Indeed, we can benefit a lot from micro-welding techniques. A lot of our appliances and gadgets are actually made out of different micro-welding procedures. Even the oven toaster is built using the micro-welding technique. If you try to turn on your oven, you will see that the heater is color orange and definitely it was not made of copper since copper cannot withstand extreme heat. Steel is actually used in the oven’s heater, intuitively attached using a laser welding.
We must be thankful for the advancement of micro-welding, for it makes our life more comfortable. We can fix our gadgets and appliances and even make them appear like brand new using micro-welding techniques! But don’t get overwhelmed, though! Always remember that only a trained and well-versed person is capable of carrying out this revolutionized welding procedure. Thus, if you want to get the best out of micro-welding techniques, always consult an expert first!
