Orbital welding machine for tube to tubesheet welding is a high-precision automated welding equipment. The equipment adopts a servo drive system to achieve 360° rotation welding to ensure uniform and defect-free welds. In addition, the orbital welding machine for tube to tubesheet welding is equipped with an intelligent control system that can preset a variety of welding parameters to adapt to a variety of materials such as stainless steel, titanium alloy, and nickel-based alloy.

Our company's automatic orbital tube to tubesheet welding head is programmed automatically throughout the welding process. Simply inputting the pipe diameter and thickness can achieve fully automatic circumferential welding. According to the requirements of the weld, the parameters such as the current size, rotation speed and time of the weld can also be fine-tuned to ensure the realization of high-quality welds. Pure argon is used as a protective gas, and the weld is uniform and beautiful.

During the heat exchanger manufacturing process, the welding of the tube to tubesheet connections is known to be a challenging task. The heat exchanger welding automation machine launched by our company is suitable for the welding needs of various types of heat exchangers such as plate type and shell and tube type. Achieve higher standards in heat exchanger welding by installing a welding automation machine.
