In some processes ( for example, arc welding ), electric current is directly applied to the workpiece.
The electrodes employed for twin-carbon arc welding are approximately of the same diameter as the workpiece thickness.
In open-air applications, such as construction and outdoors repair, shielded metal arc welding is the most common process.
Although spot welding does not generate UV light as intensely as arc welding, eye protection is nevertheless required.
Among those who collaborated with the company were Karol Adamiecki and the pioneer of arc welding StanisBaw Olszewski.

This process is being replaced by gas metal-arc welding, mainly because of the availability of inexpensive inert gases.
FCAW was first developed in the early 1950s as an alternative to shielded metal arc welding ( SMAW ).
