WHAT IS ARC WELDING?
Atomic hydrogen welding is a process produced by an electric arc between two tungsten electrodes in a hydrogen atmosphere. The hydrogen gas is dissociated in the arc; when it comes into contact with the metal, it recombines, releasing significant amounts of heat.
Carbon Electrode Welding
Carbon arc welding uses a non-consumable electrode, made of carbon or graphite, to establish an arc between itself and the workpiece or another carbon electrode.
It should be noted that the electrode erodes easily and produces carbon monoxide (CO) gases.
Metal Electrode Welding
In metal electrode welding, an electric arc is struck between the pieces to be joined and an electrode that serves as filler material to create the joint.
Metal electrode welding is the most commonly used method in metal structure construction.
Uses and Applications of Electric Arc Welding
Electric arc welding is used across various industries, such as in the manufacturing of metal parts and structures, pipe systems, tanks, and for repairing steel structures damaged by erosion and corrosion.
Electric Arc Welding Machines
Advantages of Electric Arc Welding
- Electric arc welding is a fast fabrication process that does not require curing times.
- High operating efficiency for machining applications.
- Deep weld penetration.
- Much lower distortion.
- Suitable for indoor or outdoor use.
- Cleaning and surface preparation is simple and quick.
- When properly executed, the mechanical strength of the weld joint exceeds that of the base material.
- High deposition rates (over 45 kg/h).
- Minimal ultraviolet light and fumes compared to shielded metal arc welding (SMAW).
- Consumables are easy to transport and require less storage space compared to those used in concrete construction.
- Requires less manual labor than other construction processes.
- Metals of different cross-sections can be joined.
- Joints can be easily repaired.
- Welds that fail quality requirements can be removed and re-welded.
- There are compact machines that can be carried and operated by a single person.
- The arc is always covered by a flux shield, so there is no risk of weld splatter.
