Why are more and more people choosing 2000W laser welding machines?

In the process of production and processing, many stainless steel products need to be connected by welding, usually using argon arc welding or traditional spot 2000W laser welding machines to complete. Although these equipment can meet the needs of production, but in the welding process will leave many welding defects, such as edge biting, incomplete welding, dense pores and cracks. It not only greatly reduces the fastness of the joint, but also becomes the corrosion source of crevice corrosion. In addition, the welder's welding technology level has certain requirements, welding cost is not low. After welding, a series of subsequent processing such as polishing is required, resulting in very low overall welding efficiency.

In recent years, with the popularization of laser welding technology, people put forward higher requirements for the processing efficiency of laser welding machine. In view of the traditional welding process of some difficulties, and traditional welding enterprises faced with professional welders, heavy environmental pollution, high cost difficulties, our company specially launched the fourth generation of hand-held laser welding machine, such as

The handheld laser welder uses the latest generation fiber lasers and is equipped with a self-developed swing welding head. It has the advantages of simple operation, beautiful weld, fast welding speed and no consumables. Used for welding STAINLESS steel, iron, galvanized sheet and other metal materials, can perfectly replace the traditional argon arc welding, resistance welding process. Widely used in cabinet kitchen and bathroom, stair elevator, shelf, oven, stainless steel doors and Windows guardrail, distribution box, stainless steel home and other industries of complex irregular welding process.

The characteristics of hand - held laser welding machine

(1) Fast welding speed, 2 ~ 10 times faster than traditional welding. One machine can save at least 2 welders a year.

Simple operation, high electro-optical conversion efficiency, low energy consumption, simple and easy to learn. Ordinary workers in the absence of professional welding master, after a short training can be on duty.

(3) The weld is smooth and beautiful, which reduces the subsequent polishing process and saves time and cost.

The wiggle welding joint developed makes up for the shortcomings of small laser solder joints, expands the tolerance range of processed parts and weld width, and obtains better weld lines.

⑸ Welder parts without deformation, no welding scar, welding firm.

[6] Laser welding has less consumables and long service life.

It's safe and environmentally friendly. The nozzle is only effective when touching metal, and the touch switch has temperature sensing.

Welding case analysis of mandarin duck pot

Yuanyang pot is a small metal piece commonly used in household kitchenware. Due to its special sealing performance requirements, after welding must ensure good sealing performance, no leakage, uniform and beautiful weld.

Conventional resistance welding

Resistance welding is a method of heating the workpiece to molten or plastic state by the resistance heat effect generated by the current flowing through the contact surface and adjacent areas of the workpiece, so that the metal is bonded. Resistance welding includes spot welding, seam welding, projection welding and butt welding. As shown in Figure 3, there are four problems in using traditional resistance welding to weld mandarin duck kettle:

(1) Slow welding speed. It takes three minutes to weld a 35-cm diameter, 9cm high Yuanyang pan.

The welding effect is general. After welding, the weld color is yellow or black, which needs to be polished in the later stage.

(3) the heat affected zone is large, and the base metal is deformed after welding.

(4) poor sealing, resistance welding is the spot welding of the workpiece, so some points are not very uniform, resulting in poor sealing.

Hand held laser welding machine welding

The hand-held laser welder can weld materials through the hand-held welding head, as shown in Figure 4. The hand - held welding head is light, flexible and easy to operate. It can meet all kinds of internal fillet welding, external fillet welding, lap welding, flat spot welding and all kinds of Angle welding. When used for welding mandarin duck kettle, it has the following four advantages:

(1) Fast welding speed. It only takes one minute to weld a 35cm diameter and 9cm high Yuanyang pan.
