In the field of welding, even the most beautiful weld seam is just a "vase" if its strength does not meet the requirements. Whether it is bridge steel structure, shipbuilding, or heavy machinery, the strength of welds directly determines the survival of the structure. Guanghong Yueda Laser Handheld Welding, with the ultimate performance tested by a 15 ton press, declares to the industry that the true welding king must withstand the dual tests of "strength" and "efficiency".

The essence of weld strength is the ability of the welded joint to resist external damage. Obtaining high-strength welds is not an easy task. Multiple factors such as welding process methods, welding materials, base metal properties, welding joint forms, and welding defects can all have an impact on it。

How to check the welding quality? After welding, welding products are not completely worry free. Sometimes, even if strict inspections are conducted before and during welding, new defects may still occur due to the changing conditions during use. Therefore, quality inspection of finished products is a key step in ensuring product quality。

There are various methods for inspecting finished products. Usually, inspection is mainly carried out from two aspects: appearance and non-destructive testing. Visual inspection can visually detect defects such as undercutting and porosity on the surface of the weld seam; Non destructive testing utilizes advanced technologies such as radiographic testing and ultrasonic testing to accurately detect defects inside the weld seam. In addition, physical inspection methods can deeply determine the problems inside the weld seam by measuring technical parameters such as temperature, pressure, and resistance.

Under ultimate load, there is no crack propagation or plastic deformation in the weld area, and the fracture surface is located in the base metal area. This result not only reflects the reliability of D70 laser handheld welding performance, but also demonstrates Guanghong Yueda's commitment to "zero compromise on industrial safety".

Double wire feeding: widening the weld bead and strengthening the bearing capacity

Guanghong Yueda D series laser handheld welding innovatively adopts an internal and external dual wire feeding collaborative system, targeting industry pain points directly. Simultaneous fusion of two welding wires, filling large gap welds in one go to avoid welding repairs and reduce material waste. Significantly widen the width of the weld bead, increase the height of the weld stack, and enhance the tensile and shear resistance.

Both the inner and outer wire feeders are compatible with wire reels with a maximum diameter of 300mm (15kg stainless steel, 20kg carbon steel), ensuring that more welding tasks can be completed in the same amount of time, doubling efficiency.

Turbo mode, with a sudden increase of 10% in penetration depth

The Guanghong Yueda D70 laser handheld welding can achieve a single pass penetration depth of up to 7mm. In critical welding scenarios that require ultra-high strength, the Turbo mode can be activated with just one click, instantly increasing the penetration depth by 10% and breaking through the traditional laser welding penetration limit. At the same time, the use of small core diameter and high brightness technology ensures that the laser continuously outputs high-quality and stable beams with constant power, eliminating weld defects such as incomplete penetration and easily meeting the requirements of thick plate welding.

Balancing Quality and Efficiency: Redefining Productivity

The Guanghong Yueda D series laser handheld welding not only wins with strength, but also deeply integrates "usability" into its genes: Level 2 minimalist UI, 7-inch intelligent touch screen, 0.48kg ultra light welding gun, 5-minute beginner speed, making complex processes "one click direct"; The four in one integrated design (laser, welding gun, wire feeder, gas cylinder) balances portability and efficiency, achieving "zero threshold" high-strength welding, and increasing the daily welding volume of a single machine by at least three times compared to traditional welding equipment.

In the industrial field where weld strength determines structural safety, the Guanghong Yueda D series laser handheld welding achieves dual improvement of product quality and efficiency through technological innovation, interpreting a profound understanding of the essence of welding. We are committed to making every weld a strength imprint that transcends the times and making welding an art. Choosing Guanghong Yueda Laser Handheld Welding is not only about choosing a device, but also about choosing a life commitment to engineering quality.
