Water heater tanks Welding Seam Tracking
The application of seam tracking in the welding of water heater plates
in the household appliance industry
The plates used in the home appliance industry are very thin, and most of the raw materials are made of stainless steel.
The processes used include argon arc welding, laser welding and other processes.
The use of these processes requires high precision in the front-end process.
At present, most manufacturers use trimming and other processes to process the workpiece again.
Even this does not meet the requirements of the welding process.
During the welding process, workers are required to manually and continuously adjust manually,
which results in low efficiency and If it is a laser welding process, then the light generated by the laser will burn to a certain extent to the eyes.
Production problems
The inner tank of the water heater is completed by the butt splicing or splicing of the head and the inner tank body.Since the manual pairing cannot ensure that the head and the inner tank are coaxial, the pairing deviation occurs;
The different press-fitting pressures on the welding table cause the left and right positions of the welding seam to shift;
or the asymmetry of the press-fitting leads to the tilt of the workpiece cylinder,
which will also cause the welding seam to deviate from the set position of the welding gun.
The occurrence of assembly and clamping deviation requires manual adjustment of the welding torch,
and manual adjustment means that it is difficult to improve production efficiency.
Solutions
The cylinder welding seam tracking system developed and produced by ATINY can be adapted to automatic welding equipment
to realize automatic and integrated production, with high output, low labor intensity and less labor,
which can greatly improve the production efficiency of water heater enterprises.
Its flexible and user-friendly design meets the requirements of modern manufacturing for multi-variety, mixed-flow mass production.
The steel cylinder welding seam tracking system independently developed by ATINY has been widely used in the pressure vessel manufacturing industry,
and is suitable for welding production links to replace manual operations!
The cylinder welding seam tracking system can complete circular seam automatic welding,
laser real-time tracking, and complete welding with high quality.
Realization principle
The laser welding seam tracker collects the welding seam information of the inner tank of the water heater in real time in front of the welding gun.
The collected seam information is sent to the PLC for data processing.
The PLC then controls the actuator through these data to realize the real-time correction function.
Features
| Real-time tracking, no pre-scanning required; | The tracking accuracy is between 0.1mm-0.5mm; |
| Horizontal and vertical two-way tracking; | Support gas shielded welding, argon arc welding, laser welding and other welding types; |
| Support the prediction function of tracking trajectory; | Support automatic tracking of circular splicing narrow welds; |
| Support anti-arc and anti-spot welding functions; | Tracking feedback control frequency: 20-100 times/s; |
| Support real-time display and remote control of images; | Support track playback function. |
| ATINY steel cylinder welding seam automatic tracking system is actually applied to the welding of water heater inner tanks, which can replace manual welding to solve the problem of welding deviation in circumferential seam welding. At the same time, it can realize single-sided welding and double-sided forming. |
