Rapid Growth and Global Leadership
China's hardware industry has consistently maintained a rapid growth trend. After years of accumulation and steady growth, it has now risen to an important position in the world of hardware products, becoming the top producer globally.
Technological Innovation Driving Change
Technological innovation, as the core driving force for the development of the hardware industry, is leading the industry out of the traditional, single-form hardware product model. It is ushering in a new era that emphasizes more humanized designs, clever combinations of materials and colors, and the perfect integration of function and form. Lightweight, thin, short, and small new hardware products have become the new fashion trend in the hardware field.
Enhanced Aesthetics in Daily Life Hardware
Hardware products closely related to our daily lives are increasingly showcasing exquisite and fashionable styles. Take sofa legs as an example. This indispensable furniture accessory not only serves a practical function but also incorporates the essence of decorative art. The materials of sofa legs are diverse, including solid wood, metal, acrylic, plastic, and alloy, each with its own characteristics.

Diverse Sofa leg Designs
Sofa legs come in a variety of shapes, such as single-hole spherical, single-hole bar-shaped, and various styles like American, vintage, modern, and European, meeting the aesthetic needs of different consumers. All these changes are inseparable from continuous technological advancements. By precisely controlling process parameters such as output power, laser irradiation time, and welding temperature curves, various types of sofa legs have emerged.
Welding Techniques in the Hardware Industry
Welding, as a manufacturing process that connects metals by heating, high temperature, or high pressure, has various classifications. Based on different standards, it can be divided into fusion welding, pressure welding, and brazing. In the sheet metal industry, basic welding techniques such as manual arc welding, argon arc welding, laser welding, and spot welding occupy an important position.
Manual Arc Welding
Manual arc welding, commonly known as electric welding, is the foundation of welding technology. It uses the heat of the arc between the manually operated welding rod and the workpiece to melt the metal, achieving welding. Its advantages include simple equipment, low cost, strong adaptability, and no need for auxiliary gas. However, it also has notable disadvantages such as high labor intensity, low efficiency, the potential for hydrogen embrittlement in some welding rods, and high skill requirements for welders.

Argon Arc Welding
Argon arc welding builds on the foundation of ordinary arc welding by introducing an argon gas protection mechanism. By using high current to melt the welding material into a liquid state on the base material, forming a molten pool, it achieves metallurgical bonding. The protective role of argon effectively prevents oxidation of the welding material, making argon arc welding suitable for welding stainless steel, ferrous metals, and other furniture legs. Its advantages include dense welding joints, no spatter, high quality; stable arc burning, concentrated heat, high efficiency; the ability to weld in all positions, unrestricted by the workpiece; low electrode consumption, and easy maintenance. However, it also faces challenges such as environmental impact, slow welding speed, and high technical requirements.

Laser Welding
Laser welding uses a focused laser beam as the energy source to bombard the weldment, generating heat to perform welding. Its advantages include fast welding speed, small heat-affected zone, low deformation, and a wide range of weldable materials. However, it also requires precise positioning of the weldment, has limitations on weldable thickness, low energy conversion rate, and expensive equipment, which are aspects to be considered in its application.

Spot Welding
Spot welding is a welding method that uses resistance heat to melt the base material metal to form weld spots. It is mainly suitable for welding thin plate components, with advantages such as short heating time, fast welding speed, simple operation, and high productivity. However, its application is limited by its working space, its unsuitability for welding thicker materials, and its inability to process workpieces requiring sealing.
