Case Study: 20% Cost Reduction For An Excavator Chassis Project Via LS Manufacturing Technical Intervention
A customer who was dealing with fatigue cracking in a Q690 high-strength steel chassis made by one of the global players in construction machinery. We showed our professionalism in custom heavy machinery parts fabrication by redesigning welding strategy and stress simulation and developing light-weighted members with drastic performance enhancement.
Client Challenges
Main beam weld area test found 3-5mm fatigue crack appeared in 800 hours heavy load test, delay the project, the 15mm Q690 excavator chassis was produced by world famous construction machinery manufacturer.
Enlarged the weld was impossible (increased the weight of chassis 10%, 15%) to require, failed to meet the design requirements, needed heavy metal fabrication technology professionals to support.
Client Core Needs: Finish fatigue cracking, need to finish the 1200 hours heavy-load test successfully, and reduce weight 5%, cost, and deliver 45 days.
LS 製造ソリューション
Professional engineering team of us examined this problem and drew the conclusion that welds quality was unreasonable and the stress was accumulated heavily was the reason that caused fatigue crack. From this solution, we put forward a three-step method to address the problem.
<オル>結果と値
The chassis successfully completed 1200 hours of intense testing after its installation because it showed no cracks which fulfilled all design specifications. The following results describe the specific outcomes of the study:
<オル>This case demonstrates that we can solve the core pain points of heavy machinery parts through process optimization, structural improvement, and stress control. You can submit your project requirements to receive customized technical solutions and precise cost estimates if your equipment parts face similar issues. The solution process enables cost reductions while improving efficiency for your organization.
How To Evaluate The Robotic Welding Capabilities Of a Custom Sheet Metal Service Provider?
Overall quality of huge-volume orders depends on the offline programming feature of 6 axis robotic welding station. Parameterization through digitalization is the prerequisite to ensure the quality of welding joins has achieved continuous quality of welding order(Quality of order and working efficiency).
Core Indicators for Evaluating Robotic Welding Capabilities
Apart from a number of other investment criteria, this three indicators are critical for assessing the robotic welding strength of a custom sheet metal service provider, which also indicate the degree of their advanced technology level and magnitude of their local supply requirement.
- Process capability index (Cpk): A robotic welding Cpk should be 1.33. Cpk of our welding station is 1.45, which is better than the industry standard. This shows our welding quality is stable.
- Offline program capability: Provide the ability to program complex parts offline, reducing programming time by 60%. Programming a 6M weld can be accomplished in 2 hours.
- Skill for Laser vision tracking system: The laser vision tracking system can automatically compensate the error of the laser position, and the maximum tracks precision is 0.1mm.
Comparison of Robotic Welding and Manual Welding
Compared with manual welding, robotic welding has advantages of higher consistency quality, higher production efficiency and lower cost. It is mostly suitable for processing of large-size heavy machinery parts, and brings great increase to industrial sheet metal welding efficiency and reduce sheet metal welding cost.
| Evaluation Indicators | Robotic Welding | Manual Welding | Advantages of Robotic Welding |
| Cpk Value | ≥1.33 | ≤0.8 | Higher Stability |
| Welding Efficiency | 8-10 meters/hour | 3-4 meters/hour | 2-3 times Efficiency Improvement |
| Weld Defect Rate | ≤0.01% | ≥1.5% | Significantly Reduced Defect Rate |
| Labor Cost | $200/day | $350/day | 43% Cost Reduction |
