🧑🏭Principles for choosing tungsten welding wire 🧑🏭
⚡️ Tungsten electrodes are welding electrodes used for argon (TIG) welding. There are several types, which can be identified as follows:
🔴 Red (WT20)
Used for welding general metals. Do not use with aluminum or magnesium.
The tip must be sharpened before every use.
Suitable for Direct Current (DC) only.
🔵 Blue (WL20)
Can be used with Direct Current (DC) and Alternating Current (AC).
The electrode tip should be sharpened before use.
Suitable for welding a wide range of metals such as stainless steel, silver, nickel alloys, titanium, and brass.
⚪️ Gray (WC20)
Used with Direct Current (DC) and requires sharpening before use.
Ideal for low-current welding, thin materials, and automatic welding.
Suitable for metals such as steel, stainless steel, nickel alloys, and titanium.
💚 Green (WP)
Best suited for aluminum welding.
Made of pure tungsten and should not be sharpened to a pointed tip when used for aluminum welding.
💛 Gold (WL15)
Used with Direct Current (DC).
The key advantage of gold-tipped tungsten is that it is environmentally friendly and can replace red (WT20) tungsten electrodes.
Highly versatile—suitable for welding steel, stainless steel, aluminum, and titanium.
