摘要
基于燃烧合成技术的燃烧机理和焊接母材的成分配制焊药,并成形可用于手工操作的燃烧型焊条,对A3钢进行焊接实验。通过对焊接试件的力学性能测试和金相分析,结果表明,焊接试件的结合方式为冶金结合,且焊缝合金凝固时析出第二相,提高焊缝合金的性能,使得试件的抗拉强度(σb)达到370MPa,抗弯强度(σf)达到1100MPa,成功实现燃烧型焊条对A3钢的焊接。
The thermal powder is mixed basing on the Combustion Synthesis（Self-propagating High-temperature Synthesis） and the components of the A3 steel, the combustion welding rod that can weld by hand is made using this thermal powder. The mode of combine is the metallurgy, and the welding line＇ alloys can separate out the second phase when it is freezing, the second phase can improve the capability of the welding line ＇ alloys, tensive strength and bending strength reach 370 MPa and 1100 MPa.
