Catastrophe failure: laser welding point “blindness”, production line urgent
On 5 march 2025, in a production workshop at a precision manufacturing enterprise in zhejiang, an anomaly occurred suddenly in a zhejiang 3000-w fibre-optic laser welding equipment - the operational interface showed a normal laser output, but the location of the welding point** was not indicated by red light**, resulting in the inability of workers to pinpoint the welding path. This equipment is the core equipment for the enterprise to process new energy vehicle battery components, with a daily average capacity of up to 5,000 units, and sudden breakdowns have brought the workshop to a standstill, with millions of orders at risk of renewal。
The initial screening of the technical supervisor, zhang zhang, found that the red light indicator system for the equipment lasers was completely non-functional, but that the main light power test was normal. Because of the lack of specialized testing tools, the team was unable to determine the cause of the failure: was the fibre-optic coupling damage? Red light module failure? Or is it internal? One minute and a second later, the head of the workshop made an emergency call to the 24-hour hotline of shanghai chaibo。
Sixteen years of experience: "emergency" in shanghai response
At 9. 47 a. M., the "emergency worksheet" process** was launched as soon as the shanghai postings service received a call for help. Based on an in-depth understanding of the laser device, the technical team quickly identified the possibility of failure:
1. **aging of red light diodes** (often in high frequency equipment)
2. **fritilation or contamination of optical beams** (caused interruption of red light transmission)
3. ** control panel signal anomaly** (modules need to be calibrated or replaced)。
At 10. 30 a. M., a senior engineer, chen ji, drove to the scene with a special kit containing the red light module of the original plant ** with a laser head of 3,000 w,** a high-precision fibre-optic beam** and a full-scope test instrument. At the same time, the rear technical team uses remote systems to access historical running data of the equipment, analyse the malfunction logs in advance and provide data support for on-site maintenance。

2-hour hypervelocity restoration: precision diagnosis + scientific process
** 12. 15 on-site diagnosis**
When chen arrived, he first checked the red light transmission path using the ** fibre-optic end detector** and found a clear dim sign at the end of the beam (figure 1) and initially determined that ** the internal refractive imbalance resulting from the ageing of the fibre-optic line**. For further verification, he removed the laser head casing and scanned the red light module with ** infrared thermal imager** to exclude the possibility of circuit overheating; the red light output strength was subsequently detected through **photopower **, with a value of only 18 per cent of the standard value, confirming that the beam was not working。
**13:00 replacement of fibre optics**
- ** step 1**: shut down the power supply of the equipment, release the remaining electricity and ensure operational safety
- ** step 2**: dismantling old fibre-optic wires, using ** dustless + high purity alcohol** clean fibre-optic interfaces
- ** step 3**: installation of new fibre-optic beams for pre-cuting, calibration of the radial congenerity with ** laser calibration **
- ** step 4**: resealed laser head, electrocuted to test red light output。
**14:05 functional validation**
Red light indicator precision recovery, further implementation of weld quality test** *: continuous welding on 2 mm stainless steel plate, with an average welding level of 98. 7%, with equipment power stability fully compliant with iso 9013。

From crisis to trust: customer value deep down
"it took only 4. 5 hours to get back to work!" the head of the workshop, wang, lamented that “shanghai exchange not only solved the problem but also helped us to optimize the equipment maintenance programme”. The potential risk of a decrease in cooling system pressure was additionally identified in the " laser head health testing report " ** submitted by chen ji team on site, and it was recommended that fibre-optic beams be replaced every 2,000 hours, reducing the failure rate by 70 per cent。
Behind this maintenance case are three central advantages of shanghai:
1. **technology database support**: accumulation of over 100,000 cases of laser equipment maintenance data to achieve troubles-species positioning
2. ** supply chain network of spare parts**: the six main storage centres throughout the country guarantee four hours for commonly used accessories
** precautionary maintenance concept**: from “facing” to “risk prevention”, extending the life cycle of equipment for clients。

As fibre-optic laser equipment moves in the direction of high power and high integration, the demand for “zero stoppage” services** becomes even more urgent. Shanghaixa redefined the standards for industrial services by constructing a three-dimensional system of services called "intelligence diagnosis + regionalization rapid response + data processing". As the maintenance logs of the enterprise record: “every emergency rescue is a test of technological deposition; every single minute of output saving is creating real value for the client。
