Engineering-First Review
We check your joint design, fit-up, and distortion risk. We also review inspection needs. You get clear feedback before we start welding
Controlled Quality & Documentation
We follow set procedures and record key checks. Visual testing is standard. We add NDT support when your project needs it.
Reliable Delivery
Fixtures and stable settings keep our output consistent. This reduces rework and makes lead times predictable.
What Is Metal Welding?
Before picking a process, it helps to know what welding must do for your part. This includes its strength, shape, and finish. Metal welding joins two or more parts using controlled heat, pressure, or both. For custom work, the goal is a strong joint. But we also need stable dimensions, a consistent look, and reliable performance. This means controlling the fit, heat, distortion, and inspection from the beginning.
At Yonglihao Machinery, we offer several welding methods. We use MIG (GMAW) for efficient production and general projects. We use TIG (GTAW) for thin parts, clean looks, and tight control. For heavy-duty or outdoor jobs, we can use stick welding (SMAW). We may use spot welding for thin sheet metal parts, based on the material stack and access. For high-volume, repetitive work, robotic welding improves consistency if parts and fixtures are controlled.
We often make fillet welds, butt joints, lap joints, and plug or spot joints. We also create pipe and tube welds based on your drawing. Our deliverables can include standard visual inspection (VT) records. We also provide NDT reports (PT/MT/UT/RT) if you specify them. Material certificates (MTC/COC) are available when our suppliers provide them. We can also supply part photos or checkpoint details for first article approval.
Types of Welding Methods
Different weld methods solve different problems. Use this guide to match your material, thickness, and quality goals.
MIG Welding (GMAW): MIG uses a continuous wire and shielding gas. It is often best for thicker metals, good cost, and fast work. We control fit-up and use stable settings. This reduces spatter, rework, and appearance issues.
TIG Welding (GTAW): TIG uses a tungsten electrode and filler wire if needed. It works well for thin materials and visible seams. It is also good for joints that need precise control. We use set prep and cleaning routines to protect the weld’s quality and look.
Stick Welding (SMAW): Stick welding is useful for some heavy-duty and outdoor jobs. It is less affected by wind than gas-shielded methods. We use it only when it matches the job’s access and quality needs.
Robotic Welding: Robotic welding is great for repetitive, high-volume parts. It provides a consistent travel speed and repeatable position. For these projects, fixture accuracy and part consistency are key.
Spot Welding: Spot welding joins thin sheets with heat and pressure. It is common in sheet metal work where speed matters. We check the sheet stack-up, access, and electrode setup during our review.
Materials Used in Metal Welding
The material grade affects heat input, distortion, and the final look. Here are common metals we weld. Final feasibility depends on the grade, thickness, and joint design.
Aluminum (e.g., 5052, 6061): Lightweight and resists corrosion. Good for brackets, frames, and housings. We control cleanliness, heat, and distortion on thin sections.
Stainless Steel (e.g., 304, 316L): Chosen for corrosion resistance in tough environments. We manage contamination risk and support seams where the finish is important.
Carbon Steel / Mild Steel (e.g., A36, Q235): Common for structural parts and industrial frames. We plan the fit-up and welding sequence to keep large parts stable.
Copper & Brass (project-dependent): Used for conductive or thermal parts but needs careful heat control. We review the drawing and functional goals before confirming the method.
Quality System & Weld Control
Quality comes from controlled steps, not from luck. This is how we keep welds consistent on every order.
Requirement Review: We confirm material, joint type, key dimensions, and inspection needs. If details are missing, we suggest options with clear cost and risk trade-offs.
WPS-Driven Welding: For qualified work, we follow defined procedures. This reduces variation in penetration, bead profile, and the heat-affected zone.
Fit-Up and Distortion Control: We use fixtures, tacking, and weld sequencing to reduce warping. For tight assemblies, we add checks before the final weld.
Auditable Inspection: Visual inspection (VT) is standard. When specified, we support NDT with defined steps. We provide records that match your requirements.
Traceability and Documentation: We can keep key build information like material certificates and inspection records. This helps support repeat orders.
