Wobble-3: The unstoppable killer of electric welding and argon arc welding

Lasermach LFWW-Series Handheld Fiber Laser Welding Machine is a new type high-power, high-end continuous welding tool which adopts a high-quality fiber laser source to produce a fiber optic beam.
After transmission processing, the light is focused on the workpiece to achieve continuous welding. It avoids the thermal strain caused by high heat production and reduces drastic the post-processing jobs. It is high ecological and is environmentally friendly, pollution-free and greatly improving the joint strength and quality of welding.
Replacing the old thermal welding systems with a hand-held type fiber laser gun, not only facilitates the welding of molds, advertising characters, kitchen utensils, doors and windows, etc., but also makes laser welding possible in outdoor operations, which indicates that the traditional welding of electric welding, argon arc welding, etc. will be definitively be replaced by fiber laser welding.
Laser beam welding (LBW) is a material-joining technique that applies laser radiation to melt the base material and create the welding joint. Laser beam welding process is related to other traditional welding methods, such as electron beam welding (EBW), tungsten plasma arc welding (PAW), or inert gas tungsten arc welding (TIG).
Laser beam welding applies a high power industrial laser to create a narrow and deep melt pool between the parts to be welded. Laser is a highly concentrated heat source that can be easily automated and installed on industrial welding cells or mounted in a handheld gun like our wobble-3, providing high welding speeds for many industrial applications.
Nevertheless, factors such as the laser beam quality or the processed materials have a great influence on the resulting geometry, microstructure, and residual stress distribution. Therefore, final results are directly dependent on the process input parameters, which means that process parameters must be carefully selected for achieving the desired quality.

WOBBLE-3: We offer best of both worlds in ONE machine!

Two Classes Of Fiber Laser Welding For Different Product Design Needs In ONE Machine

Autogenous Welding: 

  1. Materials are joined without the addition of extra materials which requires the highest level of fixturing and joint preparation. Since no material is added, it is necessary for the materials to be welded to remain in intimate contact during the welding process. Any significant separation of the materials can result in an unacceptable weld profile or complete failure of the welded joint. Wobble-3 prevent this to happen!
  2. Fixturing to ensure consistent fit-up of the weld joint is a key to successful fiber laser welding. An important benefit of fiber laser is welded joints with exceptional cosmetic appearance. In some cases, these welds are almost perfectly blended with the surrounding material. Depending on the fixturing and joint fit-up, some welds may have small amounts of concavity (which may not be acceptable for product designs that require fatigue properties similar to those of the base material) or convexity. Again Wobble-3 avoid this problems!

Additive Welding:

Material is added to the weld joint usually in the form of metallic wire or powder. Three reasons for adding material to the weld are:

  1. Joint fit-up: By adding extra material, the joint becomes more tolerant to joint mismatch. Acceptable welds may be produced from joints with less than perfect fit-up.
  2. Weld geometry: Addition of filler metal is used to control the shape and size of the weld. Maintaining a crown (convex surface of the weld) creates a reinforcement which is important for joints requiring mechanical strength and fatigue life in the overall product’s design performance.
  3. Dissimilar metals: Filler metal is added to facilitate welding of dissimilar metals and alloys which are otherwise metallurgically incompatible.
Laser welding uses high-energy laser pulses to locally heat the material in a small area.
The energy of the laser radiation diffuses into the material through heat conduction,
and the material is melted to form a specific molten pool.
It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts,
which can realize spot welding, butt welding, stack welding, sealing welding, etc.
The welding speed is fast, no treatment is needed after welding, and the quality of the weld is high.
The weld can be precisely controlled, small focus spot, high positioning accuracy, easy to automate.

Laser welding provides an efficient and stable process due to its high precision and fast production rate which has many applications in the electronics and automotive industry.

Traditionally, laser welding is done with a fixed welding head with a higher power laser having lower beam quality to give acceptable weld widths as single mode beams are too sharp leading to very narrow weld profiles.

In contrast wobble welding (or oscillation welding) is where a high beam quality laser is used with a galvo scan-head to rapidly oscillate the focal spot.

This method of welding enables much easier control of weld parameters such as weld width and depth of penetration which can lead to a more efficient welding process.

Visual comparison of projections during fiber laser welding

Welding with a laser beam reduces spark projections by 95 percent

Wobble: This new fiber laser welding technology reduces molten metal (spatter) by 95 percent or more. While traditional welding with very high projection levels can lower the quality and speed of the welding, new low-projection fiber laser technology with wobble, increases the quality and productivity of high-power fiber laser welding for industrial applications such as steel processing, automotive production and electrical equipment installations.
