The hand-held laser welding machine is small in size and easy to operate. Many people feel that the role is exaggerated, and they feel that there are many welding materials that cannot be welded. In fact, hand-held laser welding machines can weld a wide range of materials. The following briefly introduces several materials that can be welded by hand-held laser welding machines.
Stainless steel: It is important to know that the expansion coefficient of stainless steel is very high, and a slightly larger heat-affected zone during welding may cause serious deformation of the stainless steel. However, the heat-affected zone of the hand-held laser welding machine is very small, the welded stainless steel will not be deformed, and the weld seam is smooth and beautiful.
Carbon steel: Preheat carbon steel before welding, and pay attention to heat preservation after welding, which can effectively avoid cracks.
Aluminum-aluminum alloy: This metal is a highly reflective material and is prone to porosity problems when welded. Compared with other welding materials, as long as you pay attention to the welding parameters when using the hand-held laser welding machine, you can also obtain welds with good performance.
Handheld laser welding machines can also be used for welding between dissimilar metals.
