What materials can be welded by a handheld laser welding machine?
Hand-held laser welding machine is a non-contact welding equipment. Bogong laser hand-held laser welding machine adopts the latest generation of fiber laser and is equipped with double wave hand-held laser welding head.
It has the advantages of simple operation, beautiful welding seam, fast welding speed and no consumables.
It can perfectly replace the traditional argon arc welding and electric welding processes in the welding of thin stainless steel plates, iron plates, aluminum plates and other metal materials.
Next, let me introduce the materials that can be welded by the hand-held laser welding machine.
1.Stainless steel plate
The thermal expansion coefficient of stainless steel is high, and it is easy to overheat during welding. When the heat affected area is slightly large, it will cause serious deformation problems,
and the heat generated by the hand-held laser welding machine during the entire welding process is low,
coupled with the relatively low thermal conductivity, high energy absorption rate and melting efficiency of stainless steel, a well-formed, smooth and beautiful weld can be obtained after welding.
2.Carbon steel plate
Ordinary carbon steel can be directly used handheld laser welding machine to weld, the effect is comparable to stainless steel welding, and the heat effect area is smaller,
but in the welding, high carbon steel, relatively high residual temperature, so the need for preheating before welding, welding heat preservation to eliminate stress, avoid cracks.
Here it can be said that cold welding machine, medium and high carbon steel can use cold welding with cast iron wire slow welding or repair, focus on temperature control, temperature control, temperature control,
cold welding machine in the heat residual after welding is more excellent than hand-held laser welding.
3.Die steel
The hand-held laser welding machine is suitable for welding various types of die steel, and the welding effect is very good.
4. Aluminum and aluminum alloys
Aluminum and aluminum alloys are highly reflective materials, and there may be porosity problems in the molten pool or at the root during welding.
Compared with the previous metal materials, aluminum and aluminum alloys have higher parameter requirements, but as long as the selected welding parameters are appropriate ,
a weld with comparable mechanical properties to the base metal can be obtained.
5. Copper and Copper Alloys
The thermal conductivity of copper is very strong, and it is easy to cause incomplete penetration and partial fusion during welding.
Usually, the copper material is heated during the welding process to assist welding. Here I am talking about copper thin materials.
Hand-held laser welding can Direct welding, because of its energy concentration, fast welding speed, and the high thermal conductivity of copper have less effect on it.
6.Welding between dissimilar materials
The hand-held laser welding machine can be performed between a variety of dissimilar metals, such as copper-nickel, nickel-titanium, copper-titanium, titanium-molybdenum, brass-copper, low-carbon steel-copper, etc.
Laser welding can be performed under any conditions (gas or temperature).
