Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically to a welding device and welding method. Background Technology

[0002] A welding device is a device used for welding. An argon arc welding machine is a common welding device. Its specific principle is to pass argon gas around the arc welding area to protect it from air and prevent the welding area from oxidizing. It has been widely used in the field of welding.

[0003] To improve welding efficiency, argon arc welding machines are generally equipped with clamping components to hold the workpieces to be welded. However, for relatively long workpieces, they are prone to collision with the welding components during the clamping process, which can easily lead to damage to the workpieces or the welding components. At the same time, the workpieces are prone to vibration during the welding process, which can easily lead to weld collapse, voids, etc. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention provides a welding device and welding method that can prevent collisions between the workpiece to be welded and the welding assembly, and also prevent vibrations in the workpiece to be welded.

[0005] To solve the above problems, the technical solution provided by the present invention is as follows:

[0007] A support platform, wherein a sliding groove is provided on the support platform;

[0008] A sliding body that mates with the sliding groove;

[0009] Motor 1 connected to the sliding body 1;
