埋弧焊焊剂与焊丝怎么配

                       

焊剂的焊接工艺性能和化学冶金性能是决定焊缝金属化学成分和性能的因素之一。使用不同的焊剂，但使用相同的焊丝和焊接参数，焊缝的性能会有所不同。低碳钢和低合金钢都可以与不同的焊剂合理地结合。

   

One of the factors that determine the chemical composition and perfor ** nce of weld metal is the welding process perfor ** nce and chemical metallurgical perfor ** nce of flux. Different flux,but using the same welding wire and welding parameters,the perfor ** nce of weld will be different. Whether it is low carbon steel or low alloy steel,the welding wire can be reasonably combined with different flux.

   

   

   

焊剂的一般要求

   

General requirements for fluxes

   

焊剂应具有良好的冶金性能，配备适当的焊丝和焊接工艺，焊缝金属可获得适当的化学成分和良好的机械性能，工艺良好，电弧燃烧稳定，焊缝表面形成良好，焊接时有害气体较少。

   

The flux should have good metallurgical properties,equipped with appropriate welding wire and welding process,the weld metal can obtain appropriate chemical composition and good mechanical properties,with good processability,stable arc combustion,good weld su ** ce forming,and less harmful gas during welding.

   

焊剂要有一定的颗粒度和颗粒强度，以便于多次回收使用，颗粒度分为普通颗粒度和细晶焊剂粒度，普通颗粒度焊剂为2.5 ~ 0.45 mm，用于普通埋弧焊，细晶焊剂的粒度为1.25 ~ 0.28 mm，用于细丝或半自动埋弧焊。

   

The flux should have a certain particle size and particle strength to facilitate multiple recycling. The particle size is divided into ordinary particle size and fine-grained flux size. The ordinary particle size of flux is 2.5 ~ 0.45 mm,which is used for ordinary submerged arc welding. The fine-grained flux size is 1.25 ~ 0.28 mm,which is used for fine wire or semi-auto ** tic submerged arc welding.

   

   

   

焊剂含水量低，防潮性好，焊剂中机械夹杂物含量不得超过焊剂质量分数0.30%，硫和磷含量低，一般硫≤0.06％，磷≤0.08％。

   

The flux shall have low water content and good moisture resistance. The content of mechanical inclusions in the flux shall not exceed 0.30% of the ** ss fraction of the flux. The flux shall have low sulfur and phosphorus content,generally sulfur ≤ 0.06% and phosphorus ≤ 0.08%.

   

根据焊接钢的类型和焊接接头性能的要求，低合金高强度钢和低碳钢选择与母材强度相匹配的焊丝，不锈钢和耐热钢选择与母材成分相匹配的焊丝。堆焊时，应根据技术要求选择相似成分的焊丝和合金系统，并根据技术要求和生产条件选择合适的焊丝和焊剂。如有必要，应测试焊缝金属的耐腐蚀性、机械性能、抗裂性和工艺性能，以评估所选焊接材料是否合适。

   

he welding wire is selected according to the type of welding steel and the requirements of welding joint perfor ** nce,the welding wire ** tching the strength of base metal is selected for low alloy high strength steel and low carbon steel,and the welding wire ** tching the composition of base metal is selected for stainless steel and heat resistant steel. When su ** cing,the welding wire and alloy system with similar composition shall be selected according to the technical requirements,and the appropriate flux shall be selected. The appropriate combination of welding wire and flux shall also be selected according to the technical requirements and production conditions. If necessary,the corrosion resistance,mechanical properties,crack resistance and process perfor ** nce of weld metal shall be tested to evaluate whether the selected welding ** terial is suitable.
