Advanced tailoring laser welding technology is a cutting-edge process that has revolutionized manufacturing. This innovative technology uses a laser to precisely join metal parts together, creating strong, high-quality welds that are as durable as they are beautiful.

The process involves using a high-powered laser beam focused on the surface of the metal parts, causing them to melt and fuse together. Unlike traditional welding methods, which can be slow and imprecise, laser welding has many advantages that make it ideal for a wide range of applications.

One of the main advantages of laser welding is its ability to form strong, uniform welds with minimal distortion. The laser beam is highly focused, allowing precise control of the amount of heat applied to the metal part. This helps minimize warping or distortion, resulting in strong and aesthetically pleasing welds.

In addition to precision and accuracy, laser welding is also very efficient. The process is fast and can be automated, allowing high-volume production with minimal labor costs. This makes it ideal for manufacturers looking to increase productivity and reduce costs.

Another benefit of laser welding is its versatility. It can be used to join a variety of metals, including steel, aluminum and titanium, making it ideal for a variety of applications in industries such as automotive, aerospace and medical device manufacturing.

In addition, laser welding has many environmental benefits. The process produces the least amount of waste and has a lower carbon footprint than traditional welding methods, making it a more sustainable option for manufacturers looking to reduce their environmental impact.

The following is an introduction to the three laser tailor welding technologies provided by SO LUCKY:

1. Thermoforming laser tailor welding technology

The hot forming laser tailor welding technology improves the performance of the body steel plate and reduces the production cost by combining hot stamping steel plates of different thicknesses and grades.

2.Laser Tailored Coil-- Unique Laser Tailored Welding Technology (TWC)

Tailor Welded Coil (TWC) is a unique product for innovative lightweight construction of car bodies that extends the benefits of Tailored Welding technology to the coil-fed mode of operation. TWC offers laser welding with the same advantages as Tailored Blanks Coils, steel coils of different thicknesses, grades and coatings can be combined, and coil feeding operations such as progressive die, roll forming and blanking can be realized.

Laser Tailored Coil Production Process

4

To produce tailor-welded coils, two or three steel coils of different grades, thicknesses or coatings are welded together. The individual slit coils are first uncoiled and leveled on different machines. This is followed by edge preparation. These processing steps guarantee performance and the highest quality in particular. Then the slitting steel coil is laser welded in two welds. According to the user’s requirements, the laser tailor welded coil can be recoiled, or it can be cut to a certain length on a shearing machine. Benefits for users: 30% reduction in production costs.

Material introduction

*Laser tailor welding coil width can reach 2.200mm

*Can simultaneously weld up to three slit coils with widths from 50mm to 1.750mm and thicknesses from 0.6mm to 3.0mm

*Can process carbon steel and stainless steel

Features

* Body shop: side members, roof and crossmembers

* Exhaust Technology: Exhaust Shell

*Chassis technology: integral subframe

* Seat technology: side rails, backrest

3. Short seam continuous tailor welding system (SWC)

Due to the concept of modern car bodies, there is an increasing demand for laser welded blanks with short weld seams. These tailor welded blanks are usually designed for thermoforming applications or specially designed for trucks, WISCO Laser Technology has developed a new Conti system to provide customers with the best solution.

Application

The continuous tailor welding system for short welds is especially suitable for: short welds, narrow blanking width, thicker specifications, optimal blanking plate level mismatch

It is flexible, easy to access and easy to maintain. The well-known advantages of the Conti system, such as high productivity and flexibility, are still the Highlights of the new machine concept.

System R&D Goals

* Welding length 100-600mm

* Raw material plate width 120-1250mm

*Plate thickness max.4.0mm (*=depends on tailor welded blank geometry)

* After optimization, the rear end alignment of the welded plate

*All functions switch automatically

*Optimized the hot wire welding system configuration

* Optimized cleaning and maintenance access to make it faster

*Compact “container size” for easier transportation

*Excellent production capacity

*High flexibility

Advanced custom laser welding technology offers a range of advantages, making it ideal for manufacturers looking to improve the quality and efficiency of their production processes. Its precision, speed, versatility and sustainability make it an attractive choice for a wide range of applications, from high-volume production to specialized custom manufacturing. As the technology continues to develop, it could find wider use, changing the way manufacturers approach soldering and metal joining.
