4 Narrow Gap Filler Welding

Compared with traditional welding methods, laser welding has significant advantages-low heat input. Fast welding speed. Small heat affected zone. And small thermal deformation. In recent years, laser welding has been widely used in the automotive industry. shipbuilding industry. The nuclear power industry, aerospace industry. And other high-tech industries are becoming more and more widely used. Applications in daily hardware and other life-related fields have begun to grow rapidly.

Among them, for the two applications of improved weld formation and narrow gap filler wire welding, we use actual application cases to see the effect of laser filler wire welding.

The laser not only needs welding wire, but also needs to melt the base metal and form a small hole effect peculiar to laser deep fusion welding on the base material to form a deeper molten pool. The welding wire component, and the base metal metal component fully mixed. So, the element composition of the mixed molten pool, its proportion. And quality are relatively different from those of the welding wire and the base metal. Therefore, according to the performance defects of the base metal itself. And a suitable welding wire can select to be added to the welding process. so as to be on a micro level. Purposefully improve the crack resistance, fatigue resistance, corrosion resistance, wear resistance and other aspects of the weld.

In addition, laser filler wire welding use for multi-stack welding. Because it can achieve deep fusion welding with small hole effect, can achieve full fusion of the upper and lower welding passes, and avoid serious defects of unfusion. So it has welding Capability for large thickness joints.
