Injection mold parting lines and corners are critical areas that directly affect product quality and mold performance. Laser welding provides a high-precision, low-heat-input repair method for restoring worn, cracked, or damaged mold surfaces without compromising dimensional accuracy. This blog explores how laser welding works for mold repair, its advantages over traditional welding methods, and why it is widely used in precision mold maintenance industries.

Continuous laser welding and pulsed laser welding are two common laser processing modes used in industrial applications. Continuous laser welding delivers a steady energy output for high-speed and deep penetration welding, while pulsed laser welding provides controlled energy bursts for precision work and heat-sensitive materials. This article explains how each process works, their key differences, and typical applications, helping users understand when to choose continuous laser welding or pulsed laser welding in real production environments.

A keyhole in laser welding is a vapor-filled cavity created when a high-energy laser beam melts and vaporizes material. This process enables deep penetration and efficient energy absorption, making it essential for high-strength and precision welding applications. In this guide, we explain how keyholes form, why they matter, key factors affecting stability, common welding defects, and the differences between keyhole and conduction welding.
