Spot Welding Explained ｜ How It Differs from Conventional Welding in Industrial Production

Spot welding (resistance spot welding) is a fast and reliable method to join thin sheet metals, especially in automotive and appliance production lines. Learn how it works, how it differs from MIG/TIG welding, and why Siam Daiso excels in robotic spot welding. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ ■ What Is Spot Welding? Spot welding is a resistance welding method that joins two or more metal sheets using pressure and electric current at specific contact points. How it works: - Copper electrodes press against both sides of the sheets - A high current passes through the contact area - Heat generated by resistance melts the metal locally - The molten metal solidifies under pressure, creating a strong weld "spot" This process is completed in milliseconds, making it highly suitable for high-volume automated production. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ ■ Key Advantages of Spot Welding - ✅ Very fast cycle time—perfect for mass production - ✅ No filler wire or shielding gas required → lower costs - ✅ Easy integration with robotic welding arms - ✅ Clean appearance—weld is often hidden inside sheets - ✅ Reliable and repeatable quality in automated lines ■ Limitations of Spot Welding - ❌ Not suitable for thick materials (>3mm) - ❌ Electrodes must access both sides of the workpiece - ❌ Less effective on metals with very low resistance (e.g., aluminum) - ❌ Lower overall strength than full seam welds in some cases ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ ■ Spot Welding in the Automotive Industry In automobile manufacturing, spot welding is widely applied to assemble car body panels, frames, and substructures. Robotic spot welding systems ensure: - Faster cycle times - Consistent weld quality - Reduced human error Spot welding is often combined with pressing and EDP coating (Electro-Deposition Painting) in an integrated production line. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ ■ Recommended Manufacturer: Siam Daiso Industries Co., Ltd.

Understanding Press Machines｜How Metal Dies Work in Industrial Manufacturing

Discover the role of press machines and metal dies in sheet metal forming. Learn the types of presses, die functions, and key benefits for mass production. Plus, meet a leading expert in automotive metal pressing. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ 1. Introduction: Why Are Press Machines Important? Press machines are essential equipment in industrial metalworking, particularly for sheet metal forming. These machines apply high force to metal sheets through a specialized tool called a die to cut, bend, or shape them into desired forms. Pressing is a high-speed, repeatable process widely used in automotive, electronics, and appliance industries. It allows mass production of metal parts with high precision and consistent quality. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ 2. How Does a Press Machine Work? A press machine works by transferring force from a mechanical or hydraulic system to a metal die, which then forms the sheet metal into a specific shape. The basic components include: - Press Machine Frame: Generates and controls the pressing force - Metal Die: Custom-designed tool for shaping or cutting - Workpiece (Metal Sheet): The raw material to be formed ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ 3. Common Types of Press Machines 3.1 Mechanical Press Uses a flywheel and crankshaft system to deliver fast, repetitive force ✅ Best for: High-speed production of small metal parts 3.2 Hydraulic Press Uses hydraulic fluid pressure for slower, controlled movement ✅ Best for: Forming thick or complex parts with high precision 3.3 Servo Press Powered by a servo motor, allowing programmable motion profiles ✅ Best for: Complex forming tasks requiring fine control and energy efficiency ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ 4. What Is a Metal Die? A die is a precision tool installed in the press machine. It defines the final shape and dimensions of the metal part. Dies are made from hardened steel and precisely machined using CNC and EDM. Common Types of Dies: - Blanking Die – Cuts out flat shapes from sheet metal - Bending Die – Forms angles or curves - Forming Die – Shapes metal into 3D contours - Progressive Die – Performs multiple steps in a single stroke across different stations ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ 5. Advantages of Pressing with Dies - ⚙️ High production speed - ⚙️ Uniform product quality - ⚙️ Cost-effective in large volumes - ⚙️ Easy integration into automation lines - ⚙️ Suitable for complex geometries with tight tolerances ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ 6.
