Welding wire is a metal wire welding material used as a filler metal or both as a conductive material.
In gas welding and tungsten gas shielded arc welding, the welding wire is used as a filler metal;
In submerged arc welding, electroslag welding, and other consumable gas shielded arc welding, the welding wire is not only a filler metal, but also a conductive electrode. The surface of the welding wire is not coated with anti oxidation flux
Tensile Strength:

LM001, LM414, LM414N, LM430, LM462, LM491, LM504, LM509, LM535, LM551, LM552, etc. (general diameter: 2.4mm-4.0mm
Axis welding robot:
The workstation consists of an arc welding robot, a welding power supply, a welding gun wire feeding mechanism, a rotary dual station positioner, a fixture, and a control system.
This workstation is used for welding various workpieces based on a rotating shaft (with several cantilevers on top).
Multiple types of rotating shafts can be automatically welded within the same workstation by using different fixtures. The current welding position accuracy is very high. Due to the use of a dual station positioner, while welding, other stations can disassemble workpieces, greatly improving efficiency.
Technical indicators:
Shaft diameter: Ф 10-50mm, length 300-900mm, welding speed 3-5mm/s. The welding process adopts MAG mixed gas shielded welding, and the displacement machine rotates with a displacement accuracy of 0.05mm.
Widely used for high-quality and high-precision welding of various workpieces with rotating shafts,
Application:
suitable for industries such as :power, electrical, mechanical, and automotive.
If manual arc welding is used for shaft welding, the labor intensity of workers is extremely high, the consistency of the product is poor, and the production efficiency is low, only 2-3 pieces per hour.
After adopting an automatic welding workstation, the production can reach 15-20 pieces/hour, and the welding quality and product consistency are also greatly improved.

Maintenance:
A: Daily inspection and maintenance
1. Wire feeding mechanism. Including whether the wire feeding force distance is normal, whether the wire feeding duct is damaged, and whether there are abnormal alarms. 2. Is the gas flow normal. 3. Is the welding gun safety protection system functioning properly. (Prohibit turning off welding gun safety protection work) 4. Check if the water circulation system is working properly. 5. Test TCP (it is recommended to develop a testing program and run it after each shift handover)
B: Weekly inspection and maintenance
1. Scrub each axis of the robot. 2. Check the accuracy of TCP. 3. Check the residual oil level. 4. Check if the zero position of each axis of the robot is accurate. 5. Clean the filter screen behind the welding machine water tank. 6. Clean the filter screen at the compressed air inlet. 7. Clean the impurities at the welding gun nozzle to avoid blocking the water circulation. 8. Clean the wire feeding mechanism, including the wire feeding wheel, wire pressing wheel, and wire guide tube. 9. Check the hose bundle and wire guide hose for damage and breakage. (It is recommended to remove the entire hose bundle and clean it with compressed air) 10. Check whether the safety protection system of the welding gun is normal and whether the external emergency stop button is normal.
C:Monthly inspection and maintenance
1. Lubricate each axis of the robot. Add white lubricating oil to shafts 1-6. Oil number 86E006. Add butter to the red grease fittings on the RP positioner and RTS track. Oil number: 86K007 3. Add gray conductive grease to the blue oil nozzle on the RP positioner. Oil number: 86K004 4. Add lubricating oil to the needle bearing of the wire feeding wheel. (A small amount of butter is sufficient) 5. Clean the gun cleaning device and add lubricating oil to the pneumatic motor. (Normal engine oil is sufficient) 6. Clean the control cabinet and welding machine with compressed air. 7. Check the cooling water level in the welding machine water tank and replenish the coolant in a timely manner (pure water with a little industrial alcohol is sufficient). 8. Perform all weekly inspections except for completing items 1-8.
