Test Material Introduction

1. Stainless Steel

Performance Characteristics: Stainless steel is renowned for its excellent corrosion resistance and mechanical properties, making it widely used in applications requiring high durability and aesthetics. Its excellent weldability makes it a popular choice in engineering and manufacturing, especially in environments subject to extreme conditions.

Application Examples: Stainless steel is widely used in industries such as food processing, chemical engineering, medical equipment, and architectural decoration. In these industries, stainless steel welding requires ensuring a secure joint to prevent material fatigue and wear.

2. Aluminum

Welding Difficulties: Aluminum is relatively difficult to weld, primarily due to its high thermal conductivity and low melting point, which can easily lead to deformation and porosity during welding. Furthermore, the oxide film on the aluminum surface can affect weld quality, so it must be removed before welding.

Comparative Advantages: Despite its greater welding difficulty, aluminum offers advantages over other materials, such as light weight, high strength, and excellent corrosion resistance. It is particularly well-suited for applications in industries such as aerospace, automotive manufacturing, and construction. In these applications, the use of aluminum can reduce overall weight and improve energy efficiency.

3. Carbon Steel

Welding Suitability: Carbon steel is a well-welded material, offering excellent weldability and enhanced strength. Its relatively low cost and wide availability make it a preferred material for many structural and manufacturing applications.

Common Applications: Carbon steel is widely used in building structures, mechanical manufacturing, and piping systems. In these applications, carbon steel welds must ensure strength and integrity to withstand the various stresses of the working environment.

4. Iron

Welding Characteristics: Iron welds well, but special attention must be paid to corrosion issues that may occur during welding. High-quality welding ensures the durability of iron components while reducing failures due to corrosion or wear.

Related Industries: Iron is widely used in construction, heavy industry, and infrastructure construction, often in the manufacture of brackets, frames, and other load-bearing structures. Good welding techniques can enhance the load-bearing capacity and service life of structures.

Test Method

In this test, we used a 6000W handheld laser welder and set different welding parameters for each material to ensure optimal welding results. The specific parameter settings are as follows:

● Power: Depending on the characteristics of the material, the power setting ranged from 3kW to 6kW. For stainless steel and carbon steel, higher power was used to ensure thorough penetration; while aluminum, due to its higher thermal conductivity, required a lower power setting to prevent deformation.

● Welding Speed: The welding speed was adjusted based on the thickness and melting characteristics of each material. Typically, the welding speed for stainless steel and carbon steel was set between 1.5-3 m/min. Aluminum was welded at a faster speed of 3-5 m/min, while iron was welded at a moderate speed of approximately 2-4 m/min.

● Gas Shielding: During laser welding, argon was used as the shielding gas to prevent oxidation during welding. The gas flow rate was set between 10-15 L/min to ensure adequate shielding and avoid weld defects.

Through this series of scientific and standardized testing methods, the performance of the 6KW handheld laser welding machine on different materials can be comprehensively evaluated to ensure its stability and reliability in actual applications. Click here for more information

Test Results

1. Post-weld Cut Surface Quality Analysis

Post-weld cut surface quality analysis revealed that the 6KW laser welder achieved satisfactory welding results on stainless steel, aluminum, carbon steel, and iron. Detailed observation of the weld seams of each material revealed that the stainless steel cut surface was smooth and flat, with no visible pores or cracks, meeting high industry standards. While the aluminum weld surface was generally smooth, some areas showed fine pores, primarily due to aluminum's high thermal conductivity and the presence of an oxide film during welding. In contrast, the carbon steel and iron welded cut surfaces were uniform and flat, with moderate weld widths and no significant defects, demonstrating the superior performance of laser welding.

2. Post-weld Strength Testing

Strength testing of the welded joints further demonstrated the superior weld performance. In the tensile strength test of stainless steel, the joint strength exceeded the standard for the parent material.

The 6KW handheld laser welder achieved weld strengths that met acceptable industry standards for various materials and, in most cases, exceeded the original strength of the parent material, demonstrating the effectiveness and reliability of laser welding technology. Click here for more information
