Some details about hand-held laser welding machines

Jan 18, 2022

The handheld laser welding machine replaces the previous fixed optical path with a hand-held welding gun, which is flexible and convenient, and has a longer welding distance.

1. What materials can the hand-held laser welding machine weld?

Most friends who have not been exposed to laser welding will think that hand-held welding can only weld stainless steel, but compared with other laser welding equipment, hand-held welding machines are widely used, and the applicable materials include stainless steel, aluminum, iron, galvanized sheet, cold Rolled sheets, titanium alloys and other metals. It is widely used in kitchen and bathroom industry, home appliance industry, advertising industry, mold industry, stainless steel product industry, stainless steel engineering industry, door and window industry, handicraft industry, household goods industry, furniture industry, auto parts industry, etc.

2. Under what circumstances is filler wire welding required?

Generally, when the welding seam is less than 0.5 mm, no wire welding is required, and the size of the welding seam cannot exceed the welding wire. The current maximum diameter of the welding wire is 1.6 mm, so there are still certain requirements for the welding seam of the material.

3. How to choose the laser power according to the material thickness?

Laser welding machines generally have powers of 1000W, 1500W, and 2000W. 1000W can weld materials within 2 mm, 1500W can weld materials within 4 mm, and 2000W can weld materials within 6 mm.

4. How to deal with the deformation of the hand-held laser welding machine during welding?

With the continuous development of the industrial industry, the requirements for welding are getting higher and higher. While the welding market is expanding, the technology is also improving. To meet the requirements of the contemporary industrial industry, it is nothing more than high welding efficiency, good welding effect, and strong welding. , beautiful. In a word, meet the welding requirements. But it is very difficult to be able to do it without any flaws. Now, a problem encountered by laser welding equipment is unavoidable, that is welding deformation!

Deformation of the weld during welding is a common welding phenomenon. It is easy to deform in the common traditional welding process. Is there such a problem only in traditional welding? Will this problem not occur when welding with a hand-held laser welding machine? It will too! But relatively speaking, the hand-held laser welding machine is only slightly deformed, and it is impossible to say that it will not deform at all. The deformation of hand-held laser welding can be adjusted to alleviate the degree of deformation. Let's first analyze the reasons for a wave of handheld welding deformation:

1. Excessive power; high power will also cause deformation of the welding material.

2. The welding speed is too fast;

3. The material is too thin;

4. The operation method is wrong.

How to reduce the degree of deformation:

1. According to the material requirements, adjust to the appropriate power for welding;

2. The welding speed is uniform;

3. Avoid welding materials that are not within the scope of hand-held welding;

4. Preliminary training is required before operation.
