Square Tube End Sealing Welding Sample with 1500W Automatic Setup

Demonstrating the Welding Effect with a 1500W Setup

In square tube fabrication, end sealing welding is a common process used to close open tube ends for structural integrity and appearance. In this article, we share a sample welding demonstration showing the end sealing result achieved with a 1500W automatic welding setup.

This example is intended to present the welding effect and seam quality under this specific configuration, rather than define a universal power requirement.

Sample Description: Square Tube End Sealing

In this sample, a flat metal plate is welded onto the open end of a square tube, forming a continuous closed seam around the perimeter. The focus of this demonstration is on:

• Seam continuity

• Weld appearance

• Penetration stability

• Overall consistency

The welding process is fully automated to ensure stable movement and repeatable results.

Welding Setup Used in This Demonstration

For this sample display, the welding system is configured with:

• Automatic welding motion

• Stable torch positioning

• Controlled welding speed

• 1500W welding power

Under these conditions, the welding process remains stable and produces a clean, continuous seam suitable for visual inspection and quality evaluation.

Observed Welding Results

As shown in the images and process samples:

• The weld seam is continuous along all four sides

• Penetration is even and well controlled

• Spatter is minimal

• The sealed tube end shows good overall appearance

This demonstrates that, for this specific sample and material setup, a 1500W configuration is capable of achieving a satisfactory welding result.

The actual welding process and results are shown in the video:

Purpose of This Sample Display

The purpose of this sample is to:

• Visually present the welding quality

• Demonstrate seam consistency under automatic welding

• Provide a reference welding effect for similar applications

Actual welding power requirements may vary depending on material thickness, joint design, and production conditions.

Conclusion

This sample welding demonstration shows the end sealing effect achieved with a 1500W automatic welding setup on square tubes. The result provides a clear reference for seam quality and process stability in similar sample or trial conditions.

For specific projects, welding parameters can be adjusted according to actual application requirements.
