What materials can be welded by a handheld laser welding machine?

Laser welding system is an advanced welding process. The welding seam is deep and narrow, and the welding seam is bright and beautiful. Heat input is minimal. Due to the high power density, the melting process is extremely fast, the heat input to the workpiece is extremely low, the welding speed is fast, and the thermal deformation is small. During the weld formation process, the molten pool is continuously stirred and the gas is easily discharged, thereby producing a pore-free weld. The cooling rate after welding is fast, which can easily refine the weld structure, and the weld has high strength, toughness and comprehensive performance.

Laser welding of metal is one of the important links in laser material processing technology. Many factories now have welding requirements, but technically they still use the old traditional welding methods. After using the laser welding system, the labor costs, work efficiency and product quality of many companies have been greatly improved, so it has been recognized by many factories.

Facing the emergence of new products, many companies currently adopt a wait-and-see attitude, wondering whether they can meet their own needs. Today, let’s talk about what materials can fiber laser welding machine weld?

1.Stainless steel

Stainless steel has a higher thermal expansion coefficient. When welding, overheating is prone to occur. When the thermal shock area is slightly larger, serious deformation problems will occur. In addition, stainless steel has a relatively low thermal conductivity, high energy absorption and melting efficiency, and good, smooth and beautiful solder joints after welding.

2.Carbon steel

Ordinary carbon steel can be welded directly using a handheld laser welding machine. The effect is comparable to that of stainless steel welding, and the heat-affected area is smaller. Preheating is required before welding, and insulation is required after welding to eliminate stress and avoid cracks.

3 mold steel

The handheld laser welding machine is suitable for welding all types of mold steel, and the welding effect is very good.

4. Aluminum and aluminum alloys

Aluminum and aluminum alloys are highly reflective materials. Weld pools or roots may appear during welding. Compared with the previous metal materials, aluminum and aluminum alloys have higher requirements. However, as long as the laser welding parameters are selected appropriately, welds with mechanical properties comparable to those of the base metal can be obtained.

5. Copper and copper alloys

Copper conducts heat very well. Weakness and local melting are prone to occur during the welding process. Typically, copper materials are heated during the welding process to assist in the welding process. What I’m talking about here is thin copper material. Direct welding, due to its concentrated energy and fast welding speed, has less impact on it due to the high thermal activity of copper.

6. Welding between dissimilar materials

The handheld laser welding machine can weld between a variety of dissimilar metals, such as copper-nickel, nickel-titanium-titanium, copp

er-titanium-titanium-molybdenum-copper-copper, low carbon steel-copper, etc. Laser welding can be performed under gas or temperature conditions.

Most friends who have not been exposed to laser welding systems will think that they can only weld stainless steel, but compared with other welding equipment, laser welding machines have a very wide range of applications. Applicable materials include carbon steel, mold steel, alloy steel, stainless steel, titanium, nickel, tin, copper, aluminum, chromium, gold, silver and other metals and their alloys.

Laser welding machines are widely used in the welding of common welding materials in the kitchen and bathroom industry, home appliance industry, advertising industry, mold industry, stainless steel products industry, stainless steel engineering industry, door and window industry, handicraft industry, household products industry, furniture industry, auto parts industry, etc.
