Manual, Laser, and Robotic Welding of Sheet Metal Parts

Masion uses laser equipment and robotics for welding. These options allow us to handle complex projects with different quantities and specs. We use manual welding for small processes. On the other hand, laser or robotic welding is frequently used in large quantities. Our every process complies with quality standards. We can deal with various types of metals. These may include stainless steel, aluminum alloys, brass, zinc alloy sheets, copper, carbon steel, and more.

We’re using conventional welding processes, i.e. TIG, MIG, etc. Generally, we conduct visual inspections and use special solutions to check for quality issues in welding. These may include incomplete welding or welding leaks. Additionally, we can perform stretch tests, X-ray examinations, ultrasonic testing, and other inspections based on customer requirements. It allows us to deliver high-quality and high-standard sheet metal parts to your hands.

We’ve 20 robotic welding machines and 3 laser welding devices. These all can meet the requirements for large-scale production of sheet metal parts. Moreover, they guarantee the precision and efficiency that manual welding cannot replace. Robotic welding application is typically reserved for significant projects and large quantities of sheet metal components. While they increase production efficiency. Robotics welding can handle the welding of complex-shaped sheet metal parts and operate continuously for 24 hours. Therefore, it is specifically suited for large quantities and similar types of sheet metal components.

You can learn some tips for sheet metal design from this article. Understand the need, importance, and why the sheet metal design is crucial to play a key role in diverse industries. 

This guide allows you to create good sheet metal parts. We will start with the basics then discuss design best practices. Sounds exciting? Let’s delve in deeper to uncover facts.

Frequently Asked Questions

A: In the fabrication of sheet metal cabinets, we mainly process aluminum, carbon steel, stainless steel, and galvanized steel. For other sheet metal stamping or laser cutting, we can also process titanium alloy, brass, copper, and other materials.

A: The thickness of materials we commonly process for sheet metal cabinets is generally below 6mm, often dealing with sheet metal thicknesses of 1-4mm. For other sheet metal parts, we can process thicknesses below 20mm. If you have particularly thick materials, we can also discuss this as we use other processes such as plasma cutting and flame cutting to process thicknesses up to 300mm.

A: We generally have technologies such as robotic feeding, and robotic welding, and also imported NCT Amada stamping equipment, bending machines, HSG laser cutting, etc. As a vertically integrated sheet metal manufacturer, we internally handle stamping, cutting, bending, welding, riveting, surface coating, assembly, packaging, and all other sheet metal processing technologies, capable of handling all your sheet metal processing needs.

A: Feasibility Study Report: We perform computer simulations on sheet metal drawings to ensure the accuracy of the drawings and production. If any unreasonable aspects are found, we will assist you in making adjustments and modifications.
1. Material Inspection: We first trace the materials using a QR code and check the material report to ensure the accuracy and consistency of the material grade and batch number.
2. Production Process Error Prevention: Using color codes or markings to identify the production of different parts, such as automotive sheet metal left and right parts, to prevent confusion.
3. Jigs and Fixtures, Mould Error Prevention: Error prevention designs are applied to jigs, fixtures, or molds to avoid processing mistakes or incorrect orientation. Processing can only proceed if the material is placed correctly.
4. Automatic Monitoring: Our progressive die stamping uses monitoring systems to watch over the molds. If a problem occurs, it will automatically alarm and stop the machine.
5. Quality Inspection: First Sample Inspection: Before the production of sheet metal parts, we confirm that the dimensions of the first piece meet the drawing requirements, then use a first sample inspection tag for comparison with later parts.
6. Process Inspection: Our quality department personnel regularly inspect production process dimensions and keep records to ensure consistency and accuracy in manufacturing. Final Inspection: After sheet metal parts are processed, we measure every dimension, visually inspect the appearance, and also perform other functional tests, such as pressure resistance testing, gravity testing, waterproof testing, etc.
7. Quality Inspection Report: We have inspection reports for all inspections, which are kept for traceability. If there’s an issue with sheet metal parts, we can ultimately trace back to which step the problem occurred.
