Micro welding is a specialized fabrication process that transforms raw metals into intricate parts and components with unparalleled strength and durability. Whether you're a seasoned welder or just starting out, it's essential to understand the different micro welding processes available and the applications they're best suited for. Here's a closer look at five of the most common micro welding methods.
Chapter 01 / 05
Gas Tungsten Arc Welding (TIG)
TIG welding is ideal for welding thick stainless steel and other non-ferrous metals. The process uses a fixed tungsten electrode that creates a precise and intense arc to melt the metals together. TIG welding requires a high level of skill and precision to achieve strong welds, making it a popular choice for welding delicate, non-ferrous metals.
Chapter 02 / 05
Gas Metal Arc Welding (MIG)
Also known as inert metal gas welding, MIG uses a shielding gas and wire electrode to heat and join the metals. The process requires a constant voltage and direct-current power source, as well as shielding gas to protect the weld from air contaminants. MIG welding is a versatile process that's ideal for welding a wide range of metals.

Shielded Metal Arc Welding (SMAW)
Also known as stick welding, SMAW is one of the oldest micro welding methods. The process uses a replaceable stick electrode as filler material and creates an arc when the electrode contacts the base metal. The filler material melts, creating a weld that joins the metals together. SMAW is cost-effective and straightforward to use, but it releases spatter that requires cleaning.
Chapter 04 / 05
Flux Cored Arc Welding
Flux core welding is a gasless MIG welding process that uses a semi-automatic weld and a flux that creates gas shielding around the weld. This method is cost-effective and commonly used for repairing heavy equipment, making it an excellent choice for welding thicker metals.
Chapter 05 / 05
Percussion Welding
Percussion welding is a unique micro welding process that's ideal for joining dissimilar metals. The process generates a high-temperature arc, followed by a rapid, low-pressure motion that bonds the metals together. Percussion welding is commonly used in the medical device, automotive, and aerospace industries due to its precise and fast welding speeds.
Each micro welding process offers its advantages and disadvantages, making it essential to choose the right one for your specific application. Whether you're welding delicate electronics or heavy-duty equipment, the right micro welding process can make all the difference in the quality and reliability of your finished product.

What is percussion welding?
A heat-plus-impact process for joining metals.
An electric arc supplies the heat, then a rapid mechanical movement forces the two materials together, forming a full metallic bond with no filler.
Do I need filler metal, solder or flux?
No. There's no filler, solder or flux, and no electrodes to wear out.
That means cleaner joints, less waste, and no consumables to buy.
How do I know if my materials can be welded?
Start with the Parameter Finder or the weld schedules table.
