Replacement parts for CO2 welding torches

Tungsten welding rods are essential materials in metal welding, each type offering unique properties based on its color. These include gold, red, gray, and green rods, each suitable for different applications such as DC and AC welding, aluminum welding, or situations requiring stable and consistent arcs. Choosing the right welding rod ensures optimal welding performance and safety for the user.

Types of Joint and Weld Positions (According to AWS / ISO / EN / DIN)

Components of a symbol including Reference, Line, Arrow, Weld Symbols, Dimension & Other Data, Supplementary Symbols, Finish Symbols, Tail and Other Specifications

The topics can be summarized as follows.

The image above shows how a welder qualification is structured according to EN ISO 9606-1 and the different types of certificates that are possible.

Metal welding is the process of joining two pieces of metal by using heat to melt and fuse them together, sometimes with the addition of a filler metal. It creates a strong, continuous bond and is widely used in construction, manufacturing, and repair work.

Shielded Metal Arc Welding (SMAW), also known by other names such as Manual Metal Arc Welding (MMAW), Covered Electrode Welding, Stick Electrode Welding, Electric Arc Welding, and Process 111 Welding (MMA).

Tungsten Arc Welding with Gas Shielding (TIG) or other names such as TIG Welding (Tungsten Inert Gas), WIG Welding (Wolfram Inert Gas), Process 141 (TIG) (ISO 4063-1978), and Argon Welding."

Gas Metal Arc Welding (GMAW) or other names such as MIG (Metal Inert Gas), MAG (Metal Active Gas), Metal Shielding Gas (MSG) welding, Process 131 (MIG), Process 135 (MAG), and CO2 welding.

Flux-Cored Arc Welding (FCAW), also known as Flux-Cored Wire Welding, and the welding process 136.

Shielding Gas according to AWS A5.32 is a type of gas used in relation to welding coverage. It is available in both gaseous and liquid storage forms, and is used for arc welding processes—whether manual, semi-automatic, automatic, machine-assisted, or robotic systems. During welding, the gas must be in a purely gaseous state (not liquid) when used for shielding purposes.
