自动化焊接机械的优点

The advantages of automated welding machinery

　　（1）生产效率高。埋弧焊可以使用较大的电流，电弧的穿透能力较强，焊缝熔深大。埋弧焊热量集中，焊接速度快，生产效率比手工电弧焊提高5-10倍。

(1) High production efficiency. Submerged arc welding can use larger currents, with stronger arc penetration ability and greater weld penetration depth. Submerged arc welding has concentrated heat, fast welding speed, and production efficiency that is 5-10 times higher than manual arc welding.

　　（2）焊接质量高而且稳定。焊接规范可自动控制调整，保持稳定。焊剂保护效果好，防止空气对熔池金属的侵害。加上电流大，熔池金属与渣反应充分，使其成分均匀。埋弧焊焊缝金属质量高，性能稳定，且外表成形美观。

(2) The welding quality is high and stable. Welding specifications can be automatically controlled and adjusted to maintain stability. The flux has a good protective effect, preventing air from damaging the molten pool metal. Combined with high current, the metal in the molten pool reacts fully with the slag, making its composition uniform. The submerged arc welding seam has high metal quality, stable performance, and aesthetically pleasing appearance.

　　（3）节省材料和电能消耗。电弧在焊剂层下燃烧，热量的散失减少，消耗的电能也就减少。另外，中薄板焊接时可以不开坡口，焊丝金属没有飞溅损失，没有焊条头，所以能节省大量焊接金属材料。

(3) Save material and electricity consumption. The arc burns under the flux layer, reducing the loss of heat and consuming less electrical energy. In addition, when welding medium and thin plates, there is no need to make grooves, and the welding wire metal does not have splashing loss or welding rod head, so a large amount of welding metal materials can be saved.

　　（4）改善劳动条件，降低劳动强度。因为电弧在焊剂层下燃烧，焊接时看不见弧光，焊接烟雾也很小，所以，劳动条件得到很大的改善。

(4) Improve working conditions and reduce labor intensity. Because the arc burns under the flux layer, the arc light cannot be seen during welding, and the welding smoke is also very small, so the working conditions have been greatly improved.

　　（5）由于埋弧焊焊接时，电弧区不可见，因此对接头的加工和工件装配要求严格。埋弧自动焊一般要求在平焊位置进行焊接，对于位置狭窄的焊缝及薄板焊缝，采用埋弧焊有一定的困难。

(5) Due to the invisible arc zone during submerged arc welding, strict requirements are placed on the processing of joints and the assembly of workpieces. Automatic submerged arc welding generally requires welding to be carried out in the flat welding position. For narrow position welds and thin plate welds, using submerged arc welding has certain difficulties.
