耐磨板NM450现货(图1)

  使用TIG焊方式,在雷同的焊接参数下,NM450耐磨板焊接筹商的焊缝深度以及宽度都跟着板厚的增添而减小,焊接筹商的热波及区宽度跟着板厚的增添而减小,焊接筹商焊缝区得到板条马氏体组合,且跟着板厚的增添,板条马氏体束逐步减小。

Using TIG welding method, under the same welding parameters, the weld depth and width of nm450 wear-resistant plate welding agent decrease with the increase of plate thickness, the heat wave and zone width of welding agent decrease with the increase of plate thickness, and the lath martensite combination is obtained in the weld zone of welding agent, and the lath martensite beam gradually decreases with the increase of plate thickness.
将直径为85mm的低合金NM450耐磨板材制造成厚度辞别为8、15以及20mm的圆盘试样,选用TIG焊方式,使用相同的焊接参数,辞别在试样表面上实践无填充原料的焊接。TIG焊接设备为IGBT逆变式脉冲钨极氩弧焊机,型号为WSM-250/315/400.低合金NM450耐磨板的焊接结构以及零件在工程机械、船舶、桥梁、高层建筑、汽锅及压力容器、电力、百般车辆的制造中得到了平凡的使用。一般而言,使用方今焊接技艺能够很好的完成对低合金NM450耐磨板的焊接,可是跟着当代焊接结构日渐向大型化、高参数目标的发展,焊接工程结构的提早毁坏、甚而灾难性事件的产生也随之增多。
The low alloy nm450 wear-resistant plate with diameter of 85mm was made into disk samples with thickness of 8, 15 and 20mm. TIG welding method was adopted, and the same welding parameters were used. The welding without filler material on the sample surface was avoided. TIG welding equipment is IGBT inverter pulse TIG welding machine, model is wsm-250 / 315 / 400. The welding structure and parts of low alloy nm450 wear-resistant plate are widely used in the manufacturing of engineering machinery, ships, bridges, high-rise buildings, steam boilers and pressure vessels, electric power, and various vehicles. Generally speaking, the use of today's welding technology can be very good to complete the welding of low-alloy nm450 wear-resistant plate, but with the development of modern welding structure to large-scale and high parameter target, the early destruction of welding engineering structure, and even the occurrence of catastrophic events are also increasing.
其根本缘故是对低合金NM450耐磨板在百般工程结构中的焊接特色、焊接工艺、及组合功能转变的规律性,缺乏全盘的熟悉。本文以低合金NM450耐磨板TIG焊为研讨对象,商议了板厚对焊接筹商尺寸、热波及宽度、焊缝区的组合特征的波及。
The basic reason is that we are not familiar with the welding characteristics, welding process and the regularity of combination function transformation of low alloy nm450 wear-resistant plate in all kinds of engineering structures. Taking the TIG welding of low alloy nm450 wear-resistant plate as the research object, this paper discusses the influence of plate thickness on the welding dimension, heat wave and width, and the combination characteristics of weld zone.
