Traditional welders do not weld very small pieces together. Micro welders can join 0.2″ or 5mm thick to pieces as thin as .0003″ or 0.007 mm. There are many sorts of welders in the market that can give you very fine joints. For micro spot welding, you can use the pulse arc welders or the laser welders or the capacitive discharge welders. These are commonly used in the production of components of the small devices we use daily. Jewelry is also made using the micro welder.

With laser welding, the collimated light is used to join two metals together using fusion. Some joints may be tough to reach and this type of welding is perfect for such joints. If you want an automated welding process, the laser welding systems will do the job well. It is used for edge welding very much like pulse arc welding. It also adds material through a fill wire and can also join parts together without the addition of materials.

Sometimes in some pieces, the deep holes are required and with laser, you can push metals away to create empty spaces or holes. The best thing about laser welding is that the amount of heat you use is highly focused so it does not affect the surface of metals to be joined. The entire piece does not heat up and neither will your hand when you have the metal in it while welding. Some metals are highly sensitive to heat and change their appearance. For these types of metals, the laser welding systems are perfect. Other types of welding processes can damage such heat-sensitive materials and deform appearance. The process is used in many applications.

Fiber lasers are used for welding very small parts by manufacturers in the engineering, medical and electronics industries. While in automotive and aerospace industries these lasers weld much thicker materials. The process is also very economical as there is little or no wastage and little energy is used during the welding process. For precise discharge of energy, the Pulsed Micro TIG welding process is used for mold and dies repair.

This high precision type of welding discharges plasma that makes tiny welds just like the ones you can get with lasers. It too is used for edge welding. There are five types of welded joints, butt joint, corner joint, lap joint, tee-joint and edge joints. Welding the edges allows for strong and precise welds. The tungsten electrodes are the most suitable for the job. After the heated electrode contacts the surface, it is removed from it. The weld surface heats up to melt after the electrode transfers heat to it. Heating and melting take place from outside to inside. Pulse arc welding can also be used to add more materials to the joint to give it stronger. This type of process is used for melting and fusing together two parts without any filling materials.

Sometimes due to some reasons, there can be gaps between the two parts. Pulse arc welding can be used to seal the gaps between the two parts. The welding process is short and peak currents are used to quickly make the molten. This type of bonding is cost-efficient as the use of energy is low. There is a low risk of thermal damage to subject parts. There is no deformation of parts either as is the case with other types of welding.

Spot welding which is also called resistance welding is yet another low-cost welding option when you want to join small parts of metals together. The work pieces are subjected to contact with one negative and one positive electrode. The two electrodes in a way squeeze the work pieces and after the pressure is applied the current is released thus creating a weld spot.

The modern types of equipment also monitor the heat used during the welding process. The ideal setting prevents damage to the material and lets you achieve strong joints. Much like in laser welding, the process is used for small parts. You can fix the parts in a proper arrangement for components. The weld setting allows you to get consistent results time over again. This allows for mass production of parts efficiently. Most heat-sensitive parts remain safe during the welding process.

Like with any other type of production, the process parameters have to be set well. This way you can ensure your production line is going to give you profits and not losses. With substandard welding set ups the chances of making profits are bleak as you will have a lot of wastage. The best thing to do is to contact an expert and see the type of micro spot welders that are best for your application. The right equipment with the right settings will help you take the welding projects to the next level. The demand for fine welds is on the rise as a lot of consumer products are shrinking in size. So choose the right micro spot welders with the help of the experts in the field or outsource all your welding jobs to them.
