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。

Results show that when improving spot pitch in weld bonded joints with high elastic modulus adhesives, stresses in weld spot zone are decreased while stresses and strains at edges of overlap region are increased slightly. For the joints with low elastic modulus adhesives, both stress concentration degree at the weld spot and the shear strain at edges of overlap region are increased with the spot pitch increasing.

结果表明，高弹性模量胶粘剂胶焊接头中，增大焊点间距，焊点区应力减小而搭接区边缘胶层中的应力应变略有增大；低弹性模量胶粘剂胶焊接头中，焊点处应力集中程度和搭接区边缘胶层中的剪应变值都随焊点间距的增加而增大，增加焊点间距，两种接头的胶层断裂强度都将降低。
