气体保护焊接混合气体自动匹配装置的研究与设计

Research and Design of Automatic Welding Gas Mixer

气体保护焊是目前采用较为普遍的焊接方式,其中尤以混合气体保护焊应用最为广泛。在众多二元、三元混合气体组合中,尤以Ar+CO_2混合气的应用最为普遍,可使焊接效率与质量得到大大提高。因此,研究并设计焊接混合气体自动匹配装置具有重要的实际应用价值。本文主要以Ar+CO_2混合气为例,对气体混合的比例方法进行了研究,并提出了一种基于比例分配法、混配比例可调的气体混配装置设计方案,并在实际产品中予以应用,效果良好。

Gas shielded arc welding is widely used at present. Ar＋CO2 mixture is the most widely used among the many gas mixtures which can be greatly improve the welding efficiency and quality. Therefore, the research and design of welding gas mixer has great value on practical engineering. In this paper, Ar＋CO2 mixture is taken as an example to study the proportion method of gas mixing, and a design scheme of gas mixer based on proportional distribution method and adjustable mixing proportion is put forward. The technology has been used in the product and received good results.
