自动焊接机电源配置对比分析

设备焊接电源形式的配置与比较 众所周知,焊缝质量的关键因素之一是焊接电源的配置。目前围内外有四种电源配置或焊接方法,为了择优选取,我们进行了对比分析。

It is well known that one of the key factors of welding quality is the configuration of welding power. At present, there are four kinds of power supply configuration or welding methods inside and outside the enclosure. In order to select the best, we made a comparative analysis.
(1)CO2气体保护电源(熔化极)利用CO2气体做保护。优点:CO2气体价格低、生产效率高、焊接电流密度大、焊件基体熔池深、熔化效率高、熔敷速度快,生产效率比手工焊高2~4倍,而且抗锈、抗裂性能好;缺点:大电流焊接时,焊接表面成形较差、飞溅较多,焊后需人工除掉粘在工件上的飞溅物。
(1) CO2 gas protection power supply (melting pole) uses CO2 gas as protection. Advantages: low price of CO2 gas, high production efficiency, high welding current density, deep weld pool of weldment matrix, high melting efficiency, fast deposition speed, production efficiency 2 ~ 4 times higher than manual welding, and good rust and crack resistance; disadvantages: when high current welding, poor welding surface forming, more spatter, manual removal of spatter on the workpiece after welding.
(2)MIG气体保护焊(熔化极),利用氩气做保护。优点:焊接熔池深度大、焊接电弧稳定、焊缝成形好、生产效率高;缺点:因保护气体用氩气来实现焊接过程,氩气价格偏高且MIG焊接电源较CO2/MAG焊接电源在价格上贵3~4倍。
(2) MIG gas shielded welding (metal electrode), using argon as protection. Advantages: large welding pool depth, stable welding arc, good weld formation and high production efficiency; disadvantages: because argon is used as shielding gas to realize the welding process, the price of argon is on the high side, and the price of MIG welding power source is 3-4 times higher than CO2 / MAG welding power source.
(3)MAG气体保护焊电源(熔化极)。利用氩气和CO2混合气体保护,其中氩气为80%、CO2为20%.优点:焊接熔池深度大、熔敷效率高、焊接飞溅较小,可获得稳定的焊接过程和美观的焊缝。
(3) MAG gas shielded welding power supply (metal electrode). Advantages: large weld pool depth, high deposition efficiency, small welding spatter, stable welding process and beautiful weld can be obtained.
(4) TIG气体保护电源(非熔化极),利用氩气做保护。优点:由于电极只通过电流加热工件,使工件和焊丝形成熔池故没有飞溅物产生,焊缝成形美观;缺点:电弧熔池深度浅、熔敷率低、生产效率不高。因焊接过程全部采用氩气做保护,价格偏高。
(4) TIG gas protection power supply (non melting electrode), using argon as protection. Advantages: because the electrode only heats the workpiece through the current, so that the workpiece and the welding wire form a molten pool, so there is no spatter, and the weld shape is beautiful; disadvantages: the depth of the arc molten pool is shallow, the deposition rate is low, and the production efficiency is not high. Because the welding process is all protected by argon, the price is on the high side.
