Customer Request

The client’s core demands are: to introduce advanced laser technology to achieve full-process traceable management of parts, while upgrading pre-weld pretreatment processes to ensure welding quality from the source and drive green upgrading of the production process.
 
Tangshan Kaiyuan Automatic Welding Equipment Co., Ltd. (hereinafter referred to as “Kaiyuan”), as a leading domestic welding solution provider, has long been committed to providing high-quality welding equipment and technical services to the manufacturing industry. To continuously improve product quality and production efficiency, Kaiyuan, while continuously optimizing welding processes, has set its sights on the deep application of high-value-added laser technology in the equipment manufacturing sector.
 
In its existing production system, Kaiyuan faces the following core challenges:

Product traceability system urgently needs improvement: The welding equipment produced by Kaiyuan covers a variety of parts, from heavy frames to precision sensors, with many product types and complex batches. Traditional marking methods (such as labels and steel stamps) are prone to wear and falling off during long-term use and under harsh working conditions, making full-process traceability from production, quality inspection to after-sales difficult, and constraining quality management efficiency.
 
Pre-weld pretreatment process needs upgrading: The key to welding quality lies in the cleanliness of the base material surface. Traditional pretreatment methods (such as chemical cleaning and mechanical grinding) have the following pain points:
 
Chemical cleaning: Uses reagents such as acids and alkalis, producing waste liquid pollution, not meeting green production requirements, and residues may affect welding quality.
 
Mechanical grinding: Easily damages the base material surface, and it is difficult to evenly remove oxide layers and oil stains, leaving cleaning dead corners, which occasionally leads to defects such as weld porosity and slag inclusion.
 
Need to enhance brand image and product added value: As an industry benchmark enterprise, Kaiyuan hopes to further improve the standardization and aesthetics of product marking, and enhance product brand recognition and market competitiveness through clear, long-term, and professional marking.

Solution

Based on Kaiyuan’s exploration needs for high-value-added laser technology, we tailored an integrated quality improvement solution of laser marking + laser cleaning for them. This solution deeply integrates the laser marking machine and laser cleaning machine into Kaiyuan’s production system, achieving full-process optimization from parts marking to pre-weld treatment.

I. Laser Marking: Giving Products Long-term Identity Markings

The laser marking machines we provide have achieved high-precision, long-term marking and coding for Kaiyuan’s core welding equipment parts:
 
Full-category adaptability: Whether for heavy frames (carbon steel, alloy steel) or precision sensors (stainless steel, aluminum alloy), the laser marking machine can achieve high-contrast QR codes, serial numbers, and brand LOGOs on their surfaces. The marking depth is controllable, wear-resistant, and corrosion-resistant, ensuring clear readability throughout the product’s full life cycle.
 
Full-process traceability: Through interfacing with the enterprise’s MES system, the marking information of each part is bound in real time with production batches, quality inspection data, and assembly records. From raw material warehousing, production and processing, quality inspection to finished product shipment, and then to after-sales maintenance, the entire process is traceable, greatly improving quality management efficiency and problem response speed.
 
Brand image enhancement: Clear, standardized, and aesthetically pleasing laser markings have replaced traditional labels or steel stamps, significantly enhancing the professionalism and brand image of Kaiyuan’s products and strengthening end users’ trust in product quality.

II. Laser Cleaning: Safeguarding Welding Quality

The laser cleaning machines we provide have played a key role in Kaiyuan’s pre-weld pretreatment process:
 
Non-contact, non-damaging cleaning: Laser cleaning uses a laser beam to instantly strip away pollutants such as oxide layers, oil stains, and rust from the base material surface. The entire process requires no contact with the workpiece surface, generates no mechanical stress, and does not damage the substrate. It is especially suitable for parts with high surface quality requirements, such as precision sensors and thin-walled parts.
 
Dead-corner-free cleaning with uniform results: The laser beam can accurately act on surfaces of complex shapes, including weld grooves, channels, and dead corners that are difficult to handle with traditional methods, ensuring uniform and consistent cleaning results. The cleanliness of the base material surface after cleaning meets welding process requirements, providing ideal metallurgical bonding conditions for subsequent welding.

Ensuring welding quality from the source: By removing pollutants, laser cleaning greatly reduces the incidence of defects such as weld porosity, slag inclusion, and lack of fusion, significantly improving the stability and consistency of welding quality. Client feedback shows that after adopting laser cleaning, the first-pass welding yield increased by more than 15%.
 
Green and energy-saving: Laser cleaning requires no chemical reagents, produces no waste liquid or waste gas, and causes no dust pollution, aligning with Kaiyuan’s strategic direction of advancing green production.

Satisfaction

After the laser marking machine and laser cleaning machine were put into use at Tangshan Kaiyuan Automatic Welding Equipment Co., Ltd., the client highly praised the equipment’s performance and the overall cooperation.

Significantly Improved Traceability Efficiency: Feedback from the production management department shows that after the laser marking machine went online, parts traceability efficiency increased by more than 50%. Information that previously required manually flipping through paper records to find can now be quickly obtained simply by scanning a QR code, significantly accelerating the response speed to quality issues.

Stable and Controllable Welding Quality: The head of the welding workshop stated: “After the laser cleaning machine was put into use, the weld porosity rate dropped significantly, and the stability of welding quality achieved a qualitative leap. Workpieces that previously needed repeated grinding can now meet standards with a single weld, and production efficiency has improved simultaneously.”
 
Brand Image Upgrade: The marketing department fully affirmed the brand image improvement brought by laser marking. “Now when customers see the clear, standardized laser markings on our products, they have greater trust in the professionalism and quality of the products, which is very helpful for our market promotion.”
 
Green Production Implemented: The company’s EHS (Environment, Health, Safety) department highly recognized the chemical-free and pollution-free characteristics of laser cleaning, believing that the solution provides strong support for Kaiyuan to achieve its green manufacturing goals.
 
Client evaluation: “This cooperation is not just an equipment purchase, but a deep integration of laser application solutions with the equipment manufacturing production system. What you provide is not just a beam of light, but an integrated quality improvement solution covering marking traceability and cleaning pretreatment. We are honored to cooperate with such a professional team.”
 
The successful case of Tangshan Kaiyuan Automatic Welding Equipment Co., Ltd. introducing laser marking machines and laser cleaning machines fully demonstrates the deep value of our laser application solutions in the equipment manufacturing field. From part identity marking to pre-weld cleaning pretreatment, what we provide is not just individual machines, but integrated solutions that help clients achieve quality improvement, efficiency optimization, and green transformation.
