The pipeline automatic welding system adopts embedded computer technology, and the parameter control is completed by the software control system, which realizes the precise control of welding voltage, welding current, walking speed, wire feeding speed, shielding gas control and other parameters. A remote control system based on mobile Internet has been established, which can realize remote welding parameter monitoring and equipment fault diagnosis.
Output/Capacity:
We have 3 automated production lines, with an annual production capacity of more than 10,000 welding machines, more than 100 automatic internal welding machines with double gun sets, and more than 1,000 single gun automatic welding machines. It has all kinds of testing equipment such as three-coordinates, and has environmental laboratories, research and development laboratories, and welding process rooms

Manual/semi-automatic + automatic welding groove process (traditional standard groove):
Process method 1:
1. Cellulose electrode, argon arc welding, semi-automatic solid wire, RMD metal powder cored wire for bottoming
2. Filling: Fully automatic gas shielded flux core or solid core welding wire filling. Covering surface: DPS-500A+A-300N
3. Welding wire: 1.0mm solid wire, 1.2mm gas shielded flux cored wire for filling and covering surface
4. Gas: base 100% CO2 or 80% Ar+20% CO2, fill the cover surface with 80% Ar+20% CO2
Process characteristics: The equipment configuration is simple, which is twice that of the traditional welding rod.
Automatic welding groove process:
Process method 2:
1. Automatic welding, bottoming, filling and capping are integrated, there is a gap between the counterparts, and gaskets are needed: ceramic or steel gaskets on the back; no gaps and gaskets are needed for the counterparts: a layer is welded after the back is cleaned: DPS-500A+A-300N
Welding wire: 1.2mm gas shielded solid core welding wire with bottom filling and covering surface, high efficiency and low cost.
Gas: 70%CO2+ 30%Ar
Process characteristics: simple equipment configuration, high welding efficiency, 3 times that of traditional welding rods
Groove processing requirements: relatively standardized
Suitable working conditions: automatic welding of lower pressure pipelines such as water pipelines and municipal pipelines
Application:
Pipeline automatic welding (all positions upward welding):
Automatic pipe welding (all-position downward welding):
Inner ring seam welding of large pipe:
