Molds are of vital importance in industrial production. However, issues such as wear and cracks occur frequently. How should one choose the right welding repair technology? As a leading brand in the field of mold welding equipment, San Laser. This article will provide a detailed introduction to the most common mold repair welding methods and offer professional solutions.

1. Laser Welding: The First Choice for High-Precision Repair
Applicable Scenarios: Precision injection molds, die-casting molds, molds with high surface finish
Advantages:
✅ Ultra-high precision (error < 0.1mm), suitable for the repair of tiny cracks
✅ Small heat-affected zone, reducing the risk of mold deformation
✅ Compatible with automation, and can be used with robotic arms for batch repair

0. Tungsten Inert Gas Welding (TIG): A Universal Welding Solution
Applicable Materials: Stainless steel, aluminum alloy, copper alloy, etc.
Advantages:
✅ High welding strength, suitable for molds that bear high stress
✅ Widely available equipment and relatively low operation threshold
✅ Capable of repairing large-area damage
Expert Tips:
• The preheating temperature needs to be strictly controlled (for example, H13 steel needs to be preheated to 300-500℃)
• Pulse TIG welding is recommended to reduce thermal deformation

0. Cold Welding Technology: A Special Solution without Thermal Deformation
Applicable Scenarios:
• Thin-walled molds (such as electronic connector molds)
• Heat-treated molds (to avoid secondary annealing)
Advantages:
✅ Welding at room temperature, without thermal stress
✅ No need for subsequent processing, saving time
Disadvantages:
❌ The bonding strength is relatively low (about 60-70% of the base metal)
❌ Only suitable for the repair of non-stressed parts

0. Other Emerging Technologies
4.1 Friction Welding
• Heat is generated through mechanical friction, suitable for the welding of dissimilar metals
• Typical case: Repair of mold inserts
4.2 Electron Beam Welding (EBW)
• Carried out in a vacuum environment, suitable for aerospace-grade molds
• Expensive equipment, limited to high-end fields

0. Why Choose San Laser's Welding Equipment?
• Low operation difficulty: The optical path movement direction can be remotely controlled through a three-axis operating lever, saying goodbye to manual adjustment of the optical path.
• Proprietary technology: The split operation design allows you to frequently adjust parameters at a distance of up to 4 meters.
• Global service: Provide 24-hour remote technical support.

In recent years, laser welding machines have become increasingly popular with metal product manufacturers. Because like laser cutting, many advantages of laser welding are being recognized and utilized to produce better quality products with higher production efficiency and lower costs. Laser welding technology is a versatile and cost-effective method for joining metal materials.

The application of laser mold welding technology in the lithium battery industry is experiencing rapid growth, driven by advancements in precision manufacturing and the increasing demand for high-performance energy storage solutions. Below is a comprehensive analysis of its development trends:

Technological Advancements and Precision Requirements

Laser welding has become indispensable in critical battery manufacturing processes, such as welding battery tabs, cell casings, safety valves, and cooling plates. Its advantages—including minimal heat-affected zones, high repeatability, and reduced material deformation—ensure structural integrity and safety of lithium batteries. For example, laser welding enables continuous sealing of safety valves, enhancing production efficiency while maintaining consistency in large-scale manufacturing.

Market Expansion and Industry Growth

The global lithium battery laser welding market is projected to grow at a compound annual growth rate (CAGR) of [X]% from 2024 to 2030, fueled by the booming electric vehicle (EV) sector. By 2025, China’s EV market alone is expected to exceed RMB 160 billion, with laser welding playing a pivotal role in battery module assembly. Leading manufacturers, such as Han's Laser and HGTECH, are expanding their R&D investments to develop specialized equipment for high-speed, automated production lines.

Policy Support and Sustainability Trends

Government initiatives promoting carbon neutrality and green manufacturing are accelerating the adoption of laser welding. Policies emphasizing energy efficiency and reduced emissions align with the technology’s eco-friendly attributes, such as low energy consumption and zero pollutant emissions. Additionally, standardization of laser welding processes is improving quality control across the supply chain.

Challenges and Future Directions

Despite its advantages, challenges remain, including high initial equipment costs and the need for skilled operators. Future trends focus on integrating AI and IoT for real-time monitoring, adaptive welding parameters, and predictive maintenance. Innovations in fiber laser technology (e.g., quasi-continuous and continuous lasers) are expected to further enhance welding speed and flexibility for complex battery designs.

In summary, laser mold welding machines are poised to dominate lithium battery manufacturing due to their precision, scalability, and alignment with global sustainability goals. Their application will continue to expand as EV adoption rises and manufacturing processes evolve toward higher automation and intelligence.
