Technical Field

The invention relates to a welding device, in particular to a high-frequency induction brazing device for a metal hose.

Background

In the pipelines of fuel oil, engine oil system, cooling system and brake system of vehicle, the corrugated metal hose can compensate the position deviation of pipeline system caused by installation by its bending and flexibility, and can bear the relative displacement required by normal operation of two end interfaces. The bellows is a core element of the corrugated metal hose, and how to connect the joint is crucial, and the methods for connecting the joint and the metal hose are various, such as soldering, resistance welding, fusion welding, etc.

At present, manual argon arc welding is generally adopted for welding a metal hose and a joint, so that the requirement on workers is high, and the consistency of product quality is poor; on the other hand, the argon arc welding joint and the end face of the metal hose are welded mutually, so that the welding penetration is short, and the pulse resistance is poor. Therefore, how to realize reliable and high-quality welding of the metal hose and the joint is a problem to be solved urgently.
