III. Welding Capabilities & Quality Standards
Our welding services prioritize structural strength, dimensional stability, and consistent repeatable quality. The following specifications reflect the key performance factors that buyers rely on when evaluating welding service providers.
1. Welding Standards Compliance
All welding processes adhere to ISO 3834, AWS D1.1, or EN ISO 9606 standards, as required by the project scope or customer technical drawings.
2. Supported Welding Technologies
We offer MIG welding, TIG welding, Shielded Metal Arc Welding (SMAW), and robotic welding. The selection of welding method is determined based on factors such as required strength, surface appearance, heat input control, and material type.
3. Dimensional Accuracy Assurance
Fixture-based positioning ensures an assembly precision of ±1.0mm for most welded frames. For applications requiring tighter tolerances, custom fixtures can be used to achieve higher alignment accuracy.
4. Distortion & Warpage Control
We implement multiple distortion control measures, including precise heat input management, staggered welding sequences, preheating procedures, interpass cleaning, and calibrated clamping fixtures, to minimize deformation and warpage of workpieces.
5. Weld Penetration & Strength
For visible components, we guarantee a uniform weld appearance. TIG welding is exclusively used for applications with high cosmetic requirements. Optional weld grinding and polishing services are available to meet specific surface finish demands.
6. Production Capacity & Scalability
Our production capabilities cover various order scales: Prototype (1-20 sets), Small Batch (50-500 sets), and Mass Production (500+ sets). For mass production orders, we utilize dedicated fixtures and optimized welding parameters to ensure efficiency and consistency.
7. Quality Inspection Protocols
Standard inspection methods include visual inspection, dimensional measurement, and fillet size verification. Upon customer request, we also provide non-destructive testing (NDT) services such as Penetrant Testing (PT), Magnetic Particle Testing (MT), and Ultrasonic Testing (UT).
