基于缆式焊丝异种钢材焊接性能工艺研究

Research on Welding Performance of Dissimilar Steel Based on Cable Welding Wire

多股焊丝是一种新型结构的焊接材料,其结构最早在2009年由中国矿业大学高顶教授首先提出[1],并授权进行了产业化生产和应用。近几年来通过对多绞股焊丝的使用研究,出现了以“多绞股焊丝”为核心的包含了焊接材料、焊丝结构、捻丝装备、弧焊电源以及特种工艺开发等多项技术研究[2]。缆式焊丝为一种多绞股焊丝,本文主要通过多缆式焊丝在异种钢间焊接试验,研究缆式焊丝在煤机中部槽组件上的焊接性能。

Multi-strand welding wire is a new type of welding material.Its structure was first proposed by Professor Gao Ding of China University of Mining and Technology in 2009[1],and was authorized for industrialized production and application.In recent years,through the research on the use of multi-stranded welding wire,a number of technical researches including welding materials,welding wire structure,twisted wire equipment,arc welding power supply and special process development have emerged with"multi-stranded welding wire"as the core[2].The cable welding wire is a kind of multi-stranded welding wire.This paper mainly studies the welding performance of the cable welding wire on the central slot assembly of the coal machine through the welding test of the multi-cable welding wire between dissimilar steels.
