Optimization of 304 stainless steel laser welding process based on the fast bees test method

Based on the engineering background of determining the reasonable combination of process parameters in engineers' proofing, a fast bees test method for optimizing process parameters was developed with reference to the ternary bees algorithm. Aiming at the high tensile strength requirement of 304 stainless steel plate in laser welding, the optimization results obtained by response surface method, bees algorithm optimization solution based on the fitting equation of response surface method and fast bees test method were compared. The optimal solutions predicted by the previous two methods were approximately 688 MPa, while the optimal process parameters obtained by the fast bees test method obtain the tensile strength of 734 MPa. The results show that compared with the response surface method, the fast bees test method can reduce the number of tests and avoid the problem of ignoring the different probability density in different regions. The fast bees test method can be used as a test method with low learning cost and emphasis on the result to highlight the test point, which can help engineers quickly obtain a better combination of process parameters in the process of proofing.
