How to Select the Right Welding Technique for Custom Metal Fabrication

Choosing the appropriate welding technology is crucial for ensuring the strength, precision and durability of custom metal fabricated parts. As a professional OEM equipment and steel structure manufacturer, Jiaxing Dingshi Machinery Manufacturing Co., Ltd delivers high-quality welded components to various industries using advanced welding technologies. Below are key factors to consider when selecting the proper welding method.

1. Material Type and Thickness

Different metal materials require different welding processes:

• Carbon steel and low-alloy steel: Typically use MIG (GMAW) or stick welding (SMAW), suitable for structural components.
• Stainless steel: TIG (GTAW) or laser welding ensures clean, corrosion-resistant welds.
• Aluminum and non-ferrous metals: Pulse TIG or MIG welding effectively reduces heat distortion.

Jiaxing Dingshi operates over 50 welding machines, including laser welding and robotic welding systems, capable of processing various materials from thin sheets to thick steel plates.

2. Production Volume and Efficiency Requirements

• Mass production: Robotic MIG or spot welding improves efficiency and ensures consistency.
• Small-batch, high-precision processing: TIG or laser welding provides better control accuracy.

We are equipped with automated welding solutions to flexibly handle both small custom batches and large OEM orders.

3. Joint Design and Strength Requirements

• Butt joints and high-load components: Submerged arc welding (SAW) or multi-pass MIG welding ensures deep penetration.
• Thin sheets and precision welding: Laser or TIG welding minimizes heat distortion.

With our 30kW laser cutting machines (plate/pipe), we ensure precise joint preparation before welding.

4. Post-Weld Surface Treatment Needs

For painting or anti-corrosion requirements, Jiaxing Dingshi provides shot blasting, sand blasting and spray painting services to enhance product durability and appearance.

5. Industry Standards and Certifications

We comply with ISO, AWS and CE welding standards, ensuring reliability for applications in construction machinery, agricultural equipment and industrial steel structures.
