以新能源汽车电池托盘为例,焊缝需兼具高强度与气密性,传统工艺难以满足需求,而TIG与MIG焊接技术为此提供了高效解决方案。 然而,铝合金的焊接却是一项挑战,因其熔点低、导热快、易氧化等特点,对焊接技术提出了极高的要求。 TIG焊凭借其独特的工艺优势,成为了连接铝合金部件的理想选择,本文将带您深入探索TIG焊铝合金的奥秘。 TIG氩焊铝合金焊接基础技巧分享(ac模式氩焊铝合金)_哔哩哔哩_bilibili

该种焊接方法于1936年起源于美国,它可以焊接任何金属,焊接过程非常清洁,几乎没有飞溅,但缺点是焊接效率较慢,在铁道车辆行业,一般做小件焊接或修补使用。 MIG焊接-----熔化极氩弧焊 一般采用直流反接(工件负极性) 直流反接的特点: 熔滴稳定,熔池保护效果好、焊缝成形好、 缺陷少、飞溅少。 现在焊接铝及其合金的方法主要是交流TIG焊和直流MIG焊据多;普通直流TIG焊机通常不是用焊接铝镁等金属;特别是采用正接法,大家都知道该接法的 电弧 特点是没有“阴极破碎”作用,故不适合焊接铝及其合金。

通过我们的分步指南,探索专业的TIG焊接铝材技术。 学习正确的准备、温度控制和焊枪角度,确保每次都能获得完美的铝材焊接效果。

TIG焊接工艺适用于几乎所有金属材料的焊接,尤其是对铝合金、不锈钢和钛合金等高熔点材料的焊接具有优势。 而MIG焊接工艺适用于低碳钢、低合金钢、不锈钢等材料的焊接。 铝合金手工TIG焊操作技巧要领 一、焊接电源要采用交流电源(以前有朋友老问我焊接不锈钢的小氩弧焊机可以焊接铝吗,这个是明确的答复),氩气需要用99.99%的高纯氩。 铝材在汽车应用中的普及让TIG焊接进入一个全新的黄金时代。 优良的机械强度和漂亮的外观让TIG焊接成为专业赛车队、汽车发烧友或业余爱好者进行焊接的首选工艺。
