co_2气体保护焊是熔化极气体保护电弧焊的一种。与手工电弧焊、埋弧焊等(渣保护)相比,它具有质量好、抗裂性强、变形小、生产率高、成本低、无渣、明弧、适应范围大、能全位置施焊等特点,有利于实现焊接机械化和自动化。要提高CO_2气体保护焊质量,最关键的问题是取得最佳工艺参数。而对一定厚度的板材,根据采用的焊丝直径,选取最合适的熔滴过渡形式是取得最佳工艺参数的先决条件.现将在实践中摸索出的熔滴过度形式和最佳工艺参数分述于下:
co_2 gas shielded welding gas arc welding is a kind of protection. Compared with manual arc welding, submerged arc welding and so on (slag protection), it has the advantages of good quality, strong crack resistance, small deformation, high productivity, low cost, no residue, bright arc, wide adaptability, And so on, is conducive to the realization of welding mechanization and automation. To improve the quality of CO 2 gas shielded welding, the most critical issue is to obtain the best process parameters. For a certain thickness of the board, according to the diameter of the wire used to select the most appropriate form of droplet transfer is the prerequisite for obtaining the best process parameters are now in practice to explore the excessive drop form and the best process parameters described Under:
