Activating agent and its application method (CN201210215534.7)》、③《It is a kind of to be swashed for the activating agent of Laser Welding and using it
Photocoagulation method (CN201010528769.2)》.Wherein 1., 2. file for nickel base superalloy, stainless steel, only 3. file
For the Laser Welding of aluminium alloy, the activating agent used by the chlorides such as lithium chloride, sodium chloride, potassium chloride and potassium fluoride, sodium fluoride,
The configuration of the fluorides such as magnesium fluoride forms.Several parts of typical similar papers can be obtained by middle National IP Network (CNKI) search：①《Aluminium alloy
The influence of activating agent and welding parameters on weld depth in AC A-TIG weld》、②《The research of Laser Welding of Aluminum Alloys technology is entered
Exhibition》、③《Influence (English) of the activating agent to 6013 aluminium alloy sheet CO2 laser welding process》.Wherein 1. paper welds for TIG
Connect, oxide active agent and its shortcoming are 2. describe only in paper does not have specific formula and solution, and 3. paper is directed to 6XXX
Series alloys conduct a research, and employ fluoride activities agent.
By patent, paper inquiry it can be found that the research of existing Laser Welding of Aluminum Alloys activating agent is seldom, only 2
Piece Patents/article has done similar introduction, and bioactive agent composition is fluoride that is hypertoxic and polluting, very big to people, environmental pollution.
