This article has studied HG70 steel and HS-70 welding wires weldings,the welded joint,welding quality,and the welding operational performance,in restricts under the welding condition,Uses HS-70 welding wires,Experiments the steel plate the weld joint stretch,degree of hardness and the resilience test result indicated that,HG70 steel and HS-70 welding wires weld joints have the low crack sensitivity,The welding quality is good,Its weld joint has the fine mechanics performance,thus explained they had the fine welding match.

0前言非调质钢具有优良的使用性能和较低的生产成本，受到普遍重视。HG70钢是武钢开发的工程结构用钢，具有强度高、低温韧性好的特点。传统高强度钢一般碳当量较高，焊接性能较差。通过加入微量合金元素、采取新的控轧和调质工艺，使得HG70钢在提高强度的同时，亦保持了较高的韧性和较低的碳当量，因而从理论上讲HG70应具有较好的焊接性能，但HG70钢与HS-70焊丝的匹配情况，还有待于分析验证。

按标准对沥青混合料进行配级后，用马歇尔实验确定了12%由擦洗法提纯的露水河硅藻土改性沥青混合料的最佳沥青用量为4.5%，用硅藻土改性沥青改性效果较好，可用做公路沥青路面的改性材料。硅藻土改性剂与沥青在强制搅拌过程中，没有发生明显的化学变化，主要是物相之间的分散、均混、吸附和交联，所以主要是物理意义上的共容，因此是否共容，混匀至关重要，只有改性剂微粒能均匀稳定的分散在沥青中不发生分层、凝聚和离析，才能达到理想的改性效果。
