Application of Laser Welding Automotive Field

Metal automotive laser welding machine have become increasingly common. The market prospects of handheld lazer weldings are getting better and better. Hand lazer welders are fast in efficiency, save labour, and are simple to operate. Inexperienced people can easily operate.

What is metal laser welding?

Metal Laser welding machine is also often called metal laser welding, energy negative feedbacklaser handheld welder, laser welding machine, automotive laser cutter, laser cold welding machine, laser argon welding machine, laser welding equipment, etc. According to its working method, it can often be divided into laser mold welding machine (manual laser welding equipment), automatic laser welding equipment, jewelry lazer welder, laser spot welding machine, optical fiber transmission fiber laser welder, galvanometer welding machine, handheld welding machine .The special laser welding equipment includes sensor welding machine, silicon steel sheet laser welding equipment, keyboard laser welding equipment.

What are the types of laser welding?

Industrial laser welder machine is a new type of welding method. It is mainly aimed at welding thin-walled materials and precision parts. It can realize spot welding, butt welding, stitch welding, sealed welding, etc., with a high aspect ratio, small weld width, and small heat-affected zone. , Small deformation, fast welding speed, smooth and beautiful welding seam, no need or simple processing after welding, high welding seam quality, no air holes, precise control, small focus spot, high positioning accuracy, easy to realize automation.

How does the metal laser welding machine operate?

The metal laser welding equipment usually does not use filler solder, so the fit gap between the parts is less than 15% of the thickness of the finest part. All parts of the parts must be relatively clean. Parameters and components can control the heat input during welding and the shape of the solder joints. Heat conduction mode welding, penetration welding, and small hole welding are performed, respectively.

What is laser welding used for?

Metal laser welder is mostly used in the car body structure, the precision requirements are relatively higher, the welding process is improved, and the noise and vibration during driving are reduced.

  1. Body welding:

The automatic laser welding is widely used in the assembly and connection of stamping parts. Including laser welding of the roof cover, laser welding of the trunk lid and laser welding of the frame;
Laser welding of body structural parts (including doors, body side frame and pillars, etc.).

The reason for using laser welding is to improve the strength of the body and solve the problem that it is difficult to implement conventional resistance spot welding in some parts.

  1. Tailored welded blanks with different thicknesses:

The use of unequal-thick laser tailor-welded blanks in body manufacturing can reduce the weight of the body, reduce the number of parts, improve safety and reliability, and reduce production costs;
