Our Welding Techniques
We utilize different welding techniques to suit different materials and project needs. Our engineers will choose the optimal process for your part’s material, thickness, and design. Here is an overview of the main welding methods we offer:
Metal Inert Gas (MIG) welding uses a continuously fed wire electrode that melts and becomes part of the weld joint. A shielding gas is used to protect the molten metal. MIG welding is highly versatile and is one of the most widely used welding processes. It is efficient for welding mild steel, stainless steel, and aluminum alloys. MIG is ideal for larger welds or higher-volume production because it’s fast and produces strong welds with minimal cleanup.
Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW), uses a non-consumable tungsten electrode to create the arc. We often add a separate filler metal by hand. TIG welding is a more precise process and is perfect for thin-gauge metals or projects requiring fine, clean welds. This method produces controlled, high-quality weld beads and is especially suited for aluminum and stainless steel parts that need a superior finish. TIG welding offers the high level of precision for sheet metal assemblies, making it great for detailed work.
Spot welding (a type of resistance welding) joins metal sheets by pressing electrodes on two sides of the sheets and passing an electric current through them. The resistance heats the metal and fuses the sheets at that spot. Spot welding is fast and cost-effective for connecting sheet metal parts, often used instead of rivets or screws. It is ideal for thin metal sections like sheet metal enclosures or automotive panels because it creates strong joints with minimal distortion. We use spot welding to quickly assemble parts such as brackets and panels with precision and repeatability.
Arc welding, commonly known as stick welding, is a traditional process that uses a flux-coated consumable electrode (a “stick”) to carry the electric arc. The intense heat melts the electrode and the base metal, forming a weld pool that solidifies into a strong joint. The flux coating on the rod burns and creates a gas shield and slag to protect the weld from contamination. Stick welding is valued for its simplicity and versatility – it works well on heavy steels and is often used for structural fabrication and repairs. This method is handy for welding thicker steel sections or for on-site construction work where other methods might not be practical.

resistance spot welding machines. This extensive setup allows us to weld everything from thin 20-gauge sheet
metal to heavier plate components with precision.
Quality is our top priority. We have a team of certified and experienced welders. Every weldment we produce
undergoes thorough inspection and testing to ensure it meets design specifications and structural integrity
requirements. Our commitment to quality helps ensure each part is welded accurately to perform reliably in
its intended application.
Welding Applications
We provide welding services for a wide variety of parts and assemblies. Below are some typical applications and use cases for our sheet metal welding services in China:
Brackets and Mounting Components
Small metal brackets, supports, and mounts that require sturdy welded joints for strength. We weld brackets used in equipment, vehicles, and appliances to ensure they can support loads and stay firmly attached.
Frames and Structural Supports
Welded frames, chassis, and structural frameworks for machines or enclosures. We join tubing, channels, and profiles into rigid frames (for example, machine bases, racks, or vehicle frames) that maintain alignment and durability.
Enclosures and Cabinets
Sheet metal enclosures, cabinets, and boxes (for electronics, appliances, etc.) that need smooth, continuous welds. Our spot and TIG welding capabilities let us assemble panels into finished housings with a clean appearance and strong seams.
Custom Assemblies and Weldments
Complex welded assemblies such as tanks, containers, fixtures, or machine parts. If your project involves multiple pieces that must be joined (from simple two-piece weldments to multi-component structures), we have the skills to fabricate it.
(These are just a few examples – if it’s made of metal, we likely can weld it!)
Materials We Weld
Our welding services cover a range of metals commonly used in sheet metal fabrication. We have experience working with:
including mild/carbon steel (cold-rolled or hot-rolled) and high-strength steel. Steel is versatile and widely used; we weld steel parts for many industries.
popular for medical, food, and chemical equipment due to its corrosion resistance. We TIG-weld stainless steel to preserve its strength and finish.
lightweight and used in electronics, automotive, and aerospace components. Our team is skilled in MIG and TIG welding aluminum, which requires careful control to avoid warping.
such as copper, brass, and other alloy sheets or components. These require special care (for example, brass and copper conduct heat quickly), and our welders adjust techniques accordingly.
If you have a specific metal or alloy not listed here, just ask – we can likely accommodate it. We will choose the appropriate welding method and settings to achieve a strong bond for the material you provide.

Project Workflow: From Design to Delivery
We manage your project every step of the way, ensuring a smooth process from the initial idea to the finished product. Here’s how a typical project unfolds:
Design & Quotation
You share your part designs or concepts with us (we can work with CAD drawings or even sketches). Our engineering team reviews the design for manufacturability and suggests improvements if needed. We then provide a detailed quote, including the welding approach, cost, and lead time. We want to make sure we understand your requirements fully at this stage.
Fabrication Preparation
Before welding, we fabricate the individual components of your part. This can include laser cutting, bending, or machining sheet metal into the required shapes. We keep tight tolerances during cutting and forming, so pieces fit together correctly for welding. The better the prep, the better the final weld!
Welding & Assembly
Next, our skilled welders assemble the pieces and weld them according to the project specifications. We choose the appropriate welding technique (MIG, TIG, spot, or arc) based on the material and design. During this stage, fixtures or jigs might be used to hold parts in place, ensuring accuracy. If your project requires other assembly steps (like inserting hardware or combining welded sub-assemblies), we handle that too. After welding, we can grind or polish the welds if a smooth finish is needed.
Finishing Processes
Many projects require finishing after welding. We offer in-house basic finishes and work with partners for special finishes. This can include powder coating, painting, plating, or anodizing to protect the metal and give it the desired appearance. For example, a welded steel enclosure might be powder coated for durability. We make sure any finishing is done without compromising the weld integrity.
Quality Inspection & Delivery
.Finally, we perform a thorough inspection on the welded assembly. Our quality team checks that dimensions are within spec, welds are sound, and the finished piece meets all requirements. Once approved, we carefully package your parts to prevent damage in transit. We then arrange delivery to your location. And we work to deliver parts timely. You can touch with us to support you until your parts are safely in hand.
