Abstract

The invention relates to the technical field of electrowelding, in particular to a water-cooled TIG welding rotating arc sensor. The water-cooled TIG welding rotating arc sensor is used for large-current TIG automatic welding. The sensor comprises an external fixed shell, a middle conductive rod and an internal conductive rotating device. The fixed shell is composed of an end cover, a speed measurement chamber, a power chamber, an eccentric chamber, a bottom cover and a cold water chamber which are arranged from top to bottom. An optical coded disc in the speed measurement chamber is connected to a hollow shaft through set screws. A photoelectric sensor is placed on an opening of the speed measurement chamber. A power device is mounted in the power chamber. An eccentric block is mounted in the eccentric chamber. The cold water chamber is mounted on the lower portion of the base cover. A welding device is mounted at the bottom of the hollow shaft. According to the water-cooled TIG welding rotating arc sensor, the water-cooled cooling manner is adopted for a welding gun, the use range of the rotating arc sensor is broadened, protective gas passes the hollow conductive rod, and therefore the mass of the sensor is reduced, and welding is facilitated.

Description

technical field [0001] The invention relates to the field of electric welding technology, in particular to a water-cooled TIG welding rotary arc sensor, which is used for high-current TIG automatic welding. Background technique [0002] Tungsten argon arc welding, TIG welding for short, also known as non-melting inert gas tungsten shielded welding, is a modern welding method. It is a welding method that uses the arc heat generated between the tungsten electrode and the workpiece to melt the base metal and filler wire (if filler wire is used) under the protection of inert gas. During welding, the shielding gas is continuously ejected from the nozzle of the welding torch, forming a gas shield around the arc to isolate the air, so as to prevent its harmful influence on the tungsten electrode, molten pool and adjacent heat-affected zone, so that high-quality welds can be obtained. Although TIG welding has shortcomings such as shallow penetration, high cost, and low efficiency, ...
