摘要
为了进一步满足煤矿产业的生产需求,保证煤矿综采工作面的安全性以及稳定性,提高液压支架的生产适应性对于液压支架生产研究与制造是一个关键性的问题。现阶段,为提高液压支架的承载能力及适应能力,Q690低合金高强度合金板在液压支架的生产制造中得到了广泛的应用,但由于该材料在焊接工艺中具有一定的淬裂倾向,因而在焊接方法选择、焊接材料选择、焊接工艺参数设置等方面需进行严格控制。本文将具体分析Q690高强板的焊接性能,并基于现阶段Q690高强板焊接工艺的研究现状,结合自身的工作经验,提出保证Q690高强板焊接接头完好的工艺技巧。
In order to satisfy the requirement of production of coal industry further and ensure the security and stability of fully mechanized coal mining face,it is a key problem for the research and produce hydraulic support that improve the productive adaptability of hydraulic support.At present stage,in order to improve the carrying capacity and adaptability of hydraulic support,the Q690 low-alloyed and high strength alloy plate was wild used in making hydraulic support.However this kind of material have hardening crack tendency when weld,therefore,the selection of weld measure,material and parameters are have strict criterion.This thesis will analysis weld performance of Q690 high strength plate,also based on the weld technique of Q690 at this stage combine with the my own working experience,raise a weld technique to ensure the Q690 high strength plate without damage of the joint when weld.
