- Considerations: Not ideal for thin metals. Difficult with non-ferrous metals like aluminum.
2. Gas Welding
- Welding Effect: Smooth, slow weld with good control over heat input.
- Suitable Steels: Carbon steel, alloy steel, stainless steel.
- Post-Processing: Minimal, may need cleaning.
- Cost: Moderate.
- Considerations: Not ideal for high-strength steels. Difficult to weld very thick sections.
3. Resistance Welding
- Welding Effect: Fast, strong welds with minimal deformation.
- Suitable Steels: Low-carbon steel, stainless steel.
- Post-Processing: Usually none.
- Cost: Moderate to high, but offers fast, automated processes, reducing labor costs in large-scale production.
- Considerations: Not suitable for thick materials or high-alloy steels.
4. Spot Welding
- Welding Effect: Creates localized weld points, typically for sheet metals.
- Suitable Steels: Low-carbon steel, stainless steel.
- Post-Processing: None.
- Cost: Low.
- Considerations: Best for thin sheets. Difficult with thick or high-alloy steels.
5. MIG/MAG Welding (Metal Inert/Active Gas)
- Welding Effect: Clean, fast welds with good penetration.
- Suitable Steels: Carbon steel, alloy steel, stainless steel, aluminum (with modifications).
- Post-Processing: Minimal, requires cleaning for aesthetics.
- Cost: Moderate.
- Considerations: Requires shielding gas. Not ideal for outdoor welding.
6. TIG Welding (Tungsten Inert Gas)
- Welding Effect: Precise, high-quality welds with excellent control.
- Suitable Steels: Stainless steel, carbon steel, alloy steel, aluminum.
- Post-Processing: Minimal, may need cleaning.
- Cost: High, but offers unmatched precision for critical applications like aerospace or medical industries.
- Considerations: Slow process, requires high skill. Difficult on thick materials.
7. Laser Welding
- Welding Effect: Extremely precise welds with minimal heat distortion.
- Suitable Steels: Stainless steel, carbon steel, high-strength steel, alloy steel.
- Post-Processing: None or minimal.
- Cost: High, but reduces post-processing costs and is ideal for high-precision projects like electronics and automotive industries.
- Considerations: Expensive equipment. Not suitable for thick materials without multi-pass welding.
8. Solid-State Welding
- Welding Effect: Produces strong bonds without melting the material.
- Suitable Steels: Carbon steel, alloy steel, stainless steel.
- Post-Processing: Usually none.
- Cost: High, but delivers stronger, more durable welds without heat-related issues, suitable for high-performance applications.
- Considerations: Requires precise control. Not suitable for very thick or brittle materials.
Our Testing
We use destructive and non-destructive testing to ensure welds are defect-free, meet stress and deformation standards, and have proper HAZ properties.
- Visual Inspection: Identifies visible defects like cracks, undercut, and porosity.
- Ultrasonic Testing (UT): Uses sound waves to detect internal flaws such as cracks and voids.
- Radiographic Testing (RT): X-ray testing reveals internal defects like gas inclusions and lack of fusion.
- Magnetic Particle Testing (MT): Uses magnetic fields to detect surface and near-surface defects in ferromagnetic materials.
- Dye Penetrant Testing (PT): Dye highlights surface cracks or defects, used for non-magnetic materials.
- Destructive Testing (DT): Measures weld strength and toughness by applying mechanical stress, ensuring real-world durability.
