For stainless steel sinks, weld quality directly determines the product’s appearance and durability. A uniform, smooth weld can enhance product value, while discolored (blackened) or deformed welds may undermine brand value and sales volume.
Recently, a local stainless steel kitchenware manufacturer in Vietnam, which had long been plagued by weld defects from traditional argon arc welding, reached out to our ANTISHICNC team via Google, hoping we could provide them with a suitable solution.
The sinks are typically made of 0.6–1.2mm stainless steel sheets. However, traditional TIG welding often leads to the following problems:
- The weld area is prone to blackening and oxidation, which affects the appearance;
- High heat input causes sheet deformation, requiring subsequent correction;
- Manual grinding is needed after welding to remove the oxide layer and slag, taking about 20–30 minutes of post-processing per unit;
- High overall cost and low efficiency, with a product pass rate of only about 85%, putting the manufacturer at a disadvantage in competing for export orders.
We recommended our 4-in-1 laser welding machine AT-1500W to this Vietnamese client, as it perfectly aligns with their needs and significantly boosts processing efficiency.
| Highly efficient and flexible operation | The lightweight welding torch enables mobile and all-around welding operations, allowing a single operator to achieve precise welding. |
| Superior weld quality | For 0.8mm stainless steel sheets, the weld width is controlled within 0.3–0.5mm, featuring a smooth surface that requires no grinding. The self-cleaning function rapidly eliminates oxidation discoloration, eliminating the need for secondary polishing. |
| Significant improvement in benefits | The processing time per unit has been reduced from 45 minutes to 18 minutes, representing an efficiency improvement of approximately 60%. Monthly polishing costs are cut by nearly $5,000, with the product pass rate rising to over 95%. |
The AT-1500W 4-in-1 laser welding machine integrates four functions—welding, cleaning, cutting and derusting—in one, and is suitable for the entire processing flow of sinks. Through precise laser energy control, it effectively reduces the heat-affected zone and prevents sheet deformation and weld oxidation. ANTISHICNC also provides full-cycle technical support, including installation training, process debugging and operation guidance. Even novice operators can get up to speed quickly after a short period of training.
