Problems solved by technology

During the welding and sealing process, whether argon covers the laser welding point on the cladding is one of the key technologies that affect the welding quality. When the existing argon tube is spraying argon, the gas volume is concentrated. The laser welding speed is also fast. Therefore, when the concentrated gas ejected cannot evenly disperse and cover the laser welding points on the cladding, the welding seal is over, resulting in welding black spots at the cladding welding, which seriously affects the cladding. The welding quality of the welding seal is very low, so that the welding yield of the cladding is very low. Once the cladding does not meet the requirements, the welded and sealed cladding that does not meet the requirements will be discarded immediately, which makes the production cost high.

Abstract

The invention discloses a laser welding machine. When a jacket needs to be welded and sealed, the jacket is vertically clamped on a jacket fixture, the position of a nozzle on a bamboo-like pipe is adjusted, so that the nozzle approaches to the jacket on the jacket fixture and is opposite to a laser welding point on the jacket, switches of the laser welding machine and an argon cylinder are opened, a laser emission head aligns to a jacket to be welded and emits laser beams, and the jacket fixture rotates to drive the jacket to rotate, so that the jacket is welded and sealed. The nozzle aligns to the laser welding point on the jacket, a wire mesh wraps a nozzle on the bamboo-like pipe, so that argon sprayed from the nozzle can be uniformly dispersed and covers the laser welding point on the jacket, welding dark spots are effectively avoided, the finished product ratio of welding and sealing of the jacket is greatly increased, and waste of the jacket is avoided, so that production cost is greatly reduced.

Description

technical field [0001] The invention relates to a laser welding machine used for welding and sealing the cladding of radioactive particle sources. Background technique [0002] radioactivity 125 I particle source is widely used in the treatment of clinical tumors at home and abroad because of its advantages of low ray energy, small effective radiation radius, high local control rate, and little damage to normal tissues. 125 The source core prepared by I needs to be loaded into a tubular cladding. The commonly used cladding material is generally titanium, because titanium has good compatibility with human tissue, and the equipment for welding and sealing the cladding is mainly a laser welding machine. During the welding and sealing process, whether argon covers the laser welding point on the cladding is one of the key technologies that affect the welding quality. When the existing argon tube is spraying argon, the gas volume is concentrated. The laser welding speed is also ...
