Principle: TIG welding uses argon as a shielding gas to heat the metal welding joint through an arc to form a weld. It can provide strong welding strength.

Applicable scenarios:suitable for welding thicker metals, especially in jewelry designs that need to withstand greater forces, such as large jewelry or accessories with frame structures.

3. Resistance welding

Principle: Resistance welding passes current through the metal contact points, and heat is generated due to resistance, which melts and combines the metals in the contact area.

Applicable scenarios:suitable for small and high-volume production, such as welding chains, earrings and other small components, especially in mass production, which can significantly improve efficiency.

4. Soft soldering

Principle: The solder used in soft soldering has a low melting point (usually below 400°C), and the solder is melted by heating to combine the metals.

Applicable scenarios:Suitable for simple repair work, preliminary assembly of jewelry or temporary connection, but not suitable for high-strength occasions.

In practical applications, the above jewelry welding technologies have their own advantages and disadvantages and applicable scenarios. Laser welding is widely used in high-end jewelry projects for its precision and beautiful welds; argon arc welding is suitable for welding thicker metals; resistance welding is suitable for efficient small-piece production; and soft welding is an ideal choice for temporary and simple welding. Choosing the right welding technology can not only improve work efficiency, but also ensure the quality and beauty of the final product.
