摘要

研究了埋弧焊对符合SAE 1020等级的低碳钢冲击性能和硬度性能的影响。以厚度为10mm的低碳钢板为基材制备埋弧焊接头的试样。采用夏比冲击试验机和布氏硬度试验机对其冲击性能和硬度进行了研究。试验结果表明,低碳钢板焊接接头具有较好的硬度和冲击强度。较好的力学性能是由于热影响区和熔合区存在较细的晶粒。通过改变焊接电压、电流、行程速度和焊剂三个工艺参数,对焊接试样进行了测试。

Effect of submerged arc welding process on hardness and impact properties of fabricated SAE 1020 low carbon steel plates
This paper studies the effects of submerged arc welding (SAW) on impact and hardness properties of the low carbon steel plate's in-line with SAE 1020 grade. The test specimen of low carbon steel plates with 10 mm thickness used as base material for preparing joint using submerged arc welding. The impact and hardness properties are investigated using Charpy impact testing machine and Brinells hardness testing machine. The results obtained for testing shows that welded joint of low carbon steel plate have superior hardness and impact strength than the other methods. The reason for better mechanical properties is due to the presence of finer grains in heat affected zone and fusion zone. Welding test samples were tested by varying the three process parameters like welding voltage, current, travel speed and fluxes.
