The platform type laser welding machine, with the structural advantages of a fixed worktable and a precision displacement system, is particularly suitable for batch welding of small and standardized components such as chainsaw silencers, balancing efficiency and stability.
1、Core Process Design
In response to the characteristics of the 0.5-2mm stainless steel shell, circular weld, and multi partition splicing of the chain saw muffler, the platform laser welding adopts the following configuration:
2、Key process parameters
| Parameter item | Standard settings | Function Description |
| Laser power | 800-1500W (stainless steel) | Ensure a penetration depth of 0.5-1.2mm to avoid burning through thin walls |
| Welding speed | 3-6m/min | Reduce heat input at high speed, deformation ≤ 0.3% |
| Spot defocus amount | -0.5mm (under surface) | Obtain wide welds to improve sealing performance |
| Shielding gas | Argon gas (flow rate 20L/min) | Prevent high temperature oxidation, weld glossiness Ra ≤ 6.3 μ m |
| Tool positioning method | Pneumatic clamping+positioning pin | Repeated clamping error ≤ 0.03mm |
3、Actual application value
A certain chain saw accessory factory adopts platform laser welding for:
Efficiency: The single shift production capacity has been increased to three times that of traditional processes, and the welding cycle has remained stable at 6 seconds per piece
Quality: The qualification rate of muffler airtightness testing (0.3MPa air pressure) has increased from 85% to 99.7%
Cost: Eliminating manual polishing (saving 0.3 yuan per piece), saving 120000 yuan in annual consumables costs
Platform laser welding, with its high cost-effectiveness, easy operation, and stable production capacity, has become the preferred solution for mass production of mufflers in small and medium-sized chain saw enterprises, especially suitable for the processing of products with high standardization.
