Argon welding is a type of electric arc welding, only with a non-consumable electrode and another principle of protecting the weld pool. An arc is ignited between the workpiece to which the mass is attached and the tungsten electrode. It does not melt, but the arc temperature is sufficient to melt the edges of the metal. Oscillations of the electrode can be controlled by the weld pool by adjusting the welding speed, seam width, penetration depth.
Argon welding is one of the more efficient welding processes. Argon welding was first used to weld bullet casing to form the required weld seam, and was later used for welding of aircraft structures and welding stainless steel sheets. Argon welding can be performed with or without an additional electrode. It has a higher operating temperature, and a faster welding speed, but it is also more difficult to control.
Mobile manufacturing, machining, and welding together are considered as important advantages in today’s production processes. Mobile welding is one of the key features for the success of modern fabrication technology. For example, mobile welding can be applied to a wide range of applications: melting and welding of silicon wafers to form semiconductor chips and the production of ultrasonic welding to weld weld sensors to the wires.
On the other hand, welding welding requires a very high input voltage and a high frequency of the current. This makes mobile welding more expensive than welding over an electric arc. Mobile welding can be used to weld discrete parts such as sliding safety gates and mining gaskets, but most mobile welding equipment is used for welding heavy machinery or industrial welds with materials such as steel and iron.
Mobile welding equipment consists of the mobile equipment for the operation of an arc, a welding machine with the mobile equipment for welding the weld, and a welding jacket. There are two types of mobile welding equipment for welding components: induction welding and wireless welding.
Induction welding can be performed at frequencies of up to 80 kHz. However, the efficiency and the distance can only be limited. Usually, the parts and materials are transported to the weld workbench, and then they are brought over to the welding machine and attached. The most common parts of a mobile welding machine are weld balls, weld stand, welding discs, welding plates, electrical wires, electrode tools and welding tools.
Wireless welding was introduced in 2007 and is a relatively new phenomenon in the welding market. Wireless welding is mainly used to weld metals to make them more compact and reduce their weight. To work with wires, the device needs to be connected to the power supply and operated by electric signals. When the wire is removed from the connector, the radio signal is released and the magnetic flux that attracts the wire is gone. A laser beam is then used to weld the wire to the weld stand.
Today, a new type of welding equipment is emerging from the industry. It is called welding wire electrification. The main aim of the new welding wire electrification equipment is to shorten the operational time of welding by eliminating the use of an external electrical power supply. When the mobile welding equipment is plugged into the welding wire, the current is only generated inside the welding wire. The main difference between this technology and current welding is that the metal is not directly exposed to the electrical energy. It is more accurate and economical than wire welding.
