The Dangers of Spatter!
Laser welding is a welding technique that uses a laser beam to join metals or thermoplastics. During the welding process, molten material from the weld pool often ejects. This ejected material, known as laser weld spatter, can cause weld defects such as incomplete fill, undercuts, pits, pores, or blowouts, effectively damaging the weld.
What is spatter during laser welding?
Weld spatter is composed of tiny droplets of molten metal on the weld surface. During laser welding, the laser beam forms a weld pool on the surface. As the temperature changes, the molten alloy vaporizes at the molecular level. These gases escape through bubbles of spatter. These bubbles spread the molten metal droplets across the surface, forming spatter.
What causes laser weld spatter?
There are many factors that contribute to laser weld spatter, including material properties, weld design, welding parameters, and equipment conditions.
?? Excessive laser weld spatter? Not only does it affect aesthetics, it can ruin your entire production line!
In traditional laser welding, spatter is often overlooked, but its harmful effects go far beyond simply being a "dirt" problem:
? Spatter can make welding appear less professional. The welder must either make corrections or redo the entire weld. Both actions waste additional work time and reduce productivity.
?
Spatter can lead to poor surface quality. As material diffuses from the molten pool, this process creates holes or voids. These voids weaken the surface strength and reduce the durability of the weld.
? Equipment contamination and malfunction. Molten metal from spatter often deposits on laser welding machine components, affecting machine operation and even causing failure.
? When molten material bubbles up, contaminated gases are released. Inhaling these gases can cause health problems, such as respiratory issues. The high temperature of the molten material can cause severe burns to the welder's skin and eyes.
?? Our equipment solves spatter problems at the source!
??? Two lasers (fiber and semiconductor) form a ring. The middle ring is the fiber energy, which has different functions. The outer ring prevents spatter, preheats the semiconductor fiber, and welds. The combination of the two ensures full penetration while reducing spatter, increasing speed and penetration depth, and is adaptable to weld deviation.
?? Dual-layer gas shielding structure: The primary gas protects the weld pool, while the auxiliary gas removes spatter, eliminating any escape.
??? High-strength protection design: Multiple isolations are implemented for the optical path, lens, and sensor areas, extending weld life by 90%.
?? More aesthetically pleasing welds: Reduced spatter and smoother welds, especially suitable for industrial pipes.
