YT506A 交直流两用优质低氢型焊条,适用于16Mn、SM50A、SPV36N、BB502等低合金钢的焊接。在65～70V 交流空载电压下施焊时,有良好的工艺性能,电弧稳定(克服了结506焊条全位置焊接,特别是立焊中电弧不稳的缺点),飞溅少,脱渣容易,熔敷金属扩散氢含量低,抗裂性好,低温韧性优于同级的日本焊条 LB52和 KS76,可以取代进口焊条,巳用在船舶、桥梁、压力容器、大型高炉、重型机械及高层建筑、工业建筑等各类重要焊接结构中。YT506A 焊条已由冶金部基建局和湖北省机械厅主持鉴定,达到国外同类产品先进水平。
YT506A AC-DC dual-use high-quality low-hydrogen electrode, suitable for 16Mn, SM50A, SPV36N, BB502 and other low-alloy steel welding. In the 65 ~ 70V AC no-load voltage welding, the good process performance, arc stability (to overcome the knot 506 full position welding electrode, especially in vertical welding arc unsteady shortcomings, splash less slag easy melting Metallurgical diffusion of low hydrogen content, good crack resistance, low temperature toughness is superior to the same level of the Japanese electrodes LB52 and KS76, can replace imported electrodes, has been used in ships, bridges, pressure vessels, large blast furnaces, heavy machinery and high-rise buildings, industrial Construction and other important types of welding structure. YT506A electrode by the Ministry of Metallurgical Construction Bureau and the Hubei Provincial Office presided over the identification of machinery to achieve the advanced level of similar foreign products.
