In the semiconductor precision manufacturing industry, the welding quality requirements of pipeline systems require process precision far exceeding those of ordinary manufacturing. As the key carrier for gas transportation, cooling circulation and vacuum maintenance, the welding of small-diameter stainless steel pipelines often needs to meet core requirements such as ultra-high cleanliness, strict material control, precision welding technology, non-destructive testing and sealing verification. Manual welding is often limited by the operator's skill level, environmental interference factors and human fatigue, and it is difficult to meet the semiconductor industry's demand for welding quality consistency.
Therefore, we have developed an innovative welding machine specifically for welding small-diameter stainless steel pipes - a split orbital welding machine. Using a self-melting welding method, it is extremely suitable for welding thin-walled stainless steel pipes with a wall thickness between 0.5 and 1.5 mm, ensuring highly consistent weld quality. Furthermore, semiconductor orbital welding machines offer advantages such as full automation, high precision, and traceability. They are core equipment for pipe connection in semiconductor equipment manufacturing, demonstrating irreplaceable value in gas systems, cooling systems, and vacuum pipelines.
The KEPUNI split-type semiconductor pipeline welding machine utilizes a self-programmable and upgradeable Siemens control system with powerful computing capabilities and flexible programming. This allows precise setting of welding parameters based on specific welding requirements and pipeline specifications, enabling customized welding processes. The German orbital welding process precisely controls the track's trajectory and welding speed, ensuring uniform and stable movement of the welding gun during welding, resulting in smooth, uniform, and aesthetically pleasing welds on both the inner and outer surfaces of the pipeline. This process also effectively controls welding heat input, minimizing the heat-affected zone and preventing changes in pipeline material properties due to overheating. This ensures the weld can withstand the high pressures required to meet the stringent requirements of semiconductor pipeline welding.
During the pipeline welding process, the welding gun often generates a lot of heat. If the heat cannot be dissipated in a timely and effective manner, the welding gun will often spark, which will not only reduce the welding quality, but also seriously affect the service life of the welding gun. The double water cooling control system can quickly take away the heat generated by the welding gun by increasing the flow and flow rate of the cooling water, making the equipment run noiseless while greatly improving the temporary load rate of the welding gun, ensuring that the equipment can complete high-intensity and high-quality welding work without frequent shutdowns for cooling, effectively improving production efficiency.
When it comes to welding quality testing, Level 1 flaw detection is a rigorous standard for examining the internal quality of welds. Advanced nondestructive testing techniques, such as X-ray and ultrasonic testing, can accurately detect defects such as pores, cracks, and slag inclusions within the weld. KEPUNI semiconductor orbital welding machines produce reliable welds, ensuring they pass Level 1 flaw detection testing, providing a strong guarantee for the safe operation of semiconductor pipelines.
The split-piece design of the welding gun makes it compact and lightweight, saving significant space and allowing easy one-handed operation, greatly enhancing operational flexibility and convenience. This makes welding operations easy to perform both outdoors and in confined spaces. Furthermore, the KEPUNI split-piece welding gun is not only suitable for welding straight pipes to straight pipes, but also easily handles complex pipe connections such as elbows and tees, demonstrating its strong adaptability and versatility.
With its advanced technology, excellent performance and wide adaptability, KEPUNI split semiconductor orbital welding machine provides a one-stop solution for the precision welding of semiconductor pipelines. It has become an indispensable key equipment in the semiconductor manufacturing industry, helping the semiconductor industry to continuously develop towards higher precision and higher quality.
