HOGI Hand-held welding machine

Many stainless steel products need to be connected by welding during the production and processing process. Generally, argon arc welding or traditional spot welding machines are used to complete the connection. Although these equipment can meet the needs of production, there will be a lot of welding left in the welding process. Defects such as: undercut, incomplete penetration, dense pores, cracks, etc. Not only greatly reduces the firmness of the joint, but also becomes a source of corrosion for crevice corrosion. In addition, there are certain requirements for the welding technology level of the welder, and the welding cost is not low. After the welding is completed, a series of subsequent processing such as grinding is required, resulting in a very low overall welding efficiency.

In recent years, with the popularization of laser welding technology, people have put forward higher requirements for the processing efficiency of laser welding machines, and handheld laser welding machines have emerged at the historic moment. The handheld laser welding machine is a new generation of laser welding equipment, which belongs to non-contact welding. The operation process does not require pressure. Its working principle is to directly irradiate a high-energy intensity laser beam on the surface of the material, and through the interaction of the laser and the material, The material is melted inside, and then cooled and crystallized to form a weld.

Hand-held welding machine

The hand-held laser welding machine fills the gap of hand-held welding in the laser equipment industry, subverts the working mode of the traditional laser welding machine, and replaces the previous fixed optical path with a hand-held type. It is flexible and convenient, and the welding distance is long. It also makes laser welding to be operated outdoors. possible.

Application fields of handheld laser welding machine

Hand-held welding is mainly aimed at laser welding of long-distance and large workpieces. It overcomes the limitations of the worktable’s stroke space. The heat-affected area during welding is small, and it will not cause work deformation, blackening, and traces on the back. The welding depth is large. It is firm and fully melted. It can not only realize thermal conduction welding, but also continuous deep penetration welding, spot welding, butt welding, stitch welding, sealing welding, seam welding, etc.

Laser welding

This process overturns the working mode of the traditional laser welding machine. It has the advantages of simple operation, beautiful welding seam, fast welding speed, and no consumables. It can weld thin stainless steel plates, iron plates, galvanized plates and other metal materials below 6mm. , It can perfectly replace traditional argon arc welding, stainless steel plate, iron plate, aluminum plate and other metal materials welding.

Hand-held laser welding is mainly aimed at the fixed position of large and medium-sized sheet metal, cabinets, chassis, aluminum alloy door and window frames, stainless steel wash basins and other large workpieces, such as inner right angle, outer right angle, and flat weld welding. The heat affected area during welding is small, and the deformation is small. Moreover, the welding depth is large and the welding is firm. Widely used in the 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, homeware industry, furniture industry, auto parts industry, etc.

Advantages of handheld laser welding machine

1. Wide welding range: The handheld welding head is equipped with 5m-10M original optical fiber, which overcomes the limitation of workbench space, and can be welded outdoors and long-distance welding.

2. Convenient and flexible to use: Hand-held laser welding is equipped with movable pulleys, which is comfortable to hold, and can adjust the station at any time. It is free and flexible, and is suitable for various working environment scenarios.

3. A variety of welding methods: welding at any angle can be realized: overlap welding, butt welding, vertical welding, flat fillet welding, internal fillet welding, external fillet welding, etc., and can be used for various complex welded workpieces and large workpieces with irregular shapes Welding, to achieve any angle welding. In addition, it can also complete cutting, welding and cutting can be switched freely, just change the welding copper nozzle to the cutting copper nozzle, which is very convenient.

4. Good welding effect: Hand-held laser welding is hot-melt welding. Compared with traditional welding, laser welding has higher energy density and can achieve better welding results. The welding area has little thermal influence, is not easy to deform, blackish, and has a back surface. The problem of traces is that the welding depth is large, the melting is sufficient, and it is firm and reliable. The welding seam strength reaches or exceeds the base metal itself, which cannot be guaranteed by ordinary welding machines.

5.The welding seam does not need to be polished: after traditional welding, the welding point needs to be polished to ensure smoothness and no roughness. The hand-held laser welding precisely reflects more advantages in the processing effect: continuous welding, smooth and no fish-scale patterns, beautiful and no scars, and less follow-up polishing procedures.

6. Welding without consumables: the welding operation in most people’s impression is “left hand goggles, right hand clamp welding wire”. But with the handheld laser welding machine, the welding can be easily completed, which reduces the material cost in production and processing.

7. With multiple safety alarms, the welding tip is only effective when the switch is touched when it touches the metal. The light is automatically locked after the workpiece is removed, and the touch switch has body temperature sensor. The safety is high to ensure the safety of the operator during work.

8. Save labor cost: Compared with arc welding, the processing cost can be reduced by about 30%. The operation is simple, easy to learn, and quick to get started. The technical threshold of operators is not high. Ordinary workers can take up their posts after a short training, which can easily achieve high-quality welding results.

Comparison of handheld laser welding machine and argon arc welding

1. Energy consumption comparison: Compared with traditional arc welding, the handheld laser welding machine saves about 80% to 90% of electric energy, and the processing cost can be reduced by about 30%.

2. Welding effect comparison: Laser hand-held welding can complete dissimilar steel and dissimilar metal welding. The speed is fast, the deformation is small, and the heat-affected zone is small. The weld seam is beautiful, smooth, no/less porosity, and no pollution. The handheld laser welding machine can be used for small open parts and precision welding.

3. Follow-up process comparison: low heat input during laser hand-held welding, small deformation of the workpiece, and beautiful welding surface can be obtained without or only simple treatment (depending on the requirements of the welding surface effect). The handheld laser welding machine can greatly reduce the labor cost of the huge polishing and leveling process.

Expansion function: add mechanical arm application

HOGI laser hand-held laser welding machine is equipped with mechanical arm application, which has the following advantages:

1. Compared with hand-held welding, the welding effect is better, the speed is stable, the welding surface is heated evenly, and the consistency is higher.

2. Welding methods are more diverse, which can realize welding of special shapes such as round, triangle, and square, and welding on the cover and surface of various columns such as cylinders and square columns.

3. Simple tooling can realize one-time positioning and repeat automatic welding, further reducing the dependence of welding on labor.
