A5.4 章节是Specification for Stainless Steel Electrodes for Shielded metal Arc Welding (即手工电弧焊不锈钢焊条规格)
E38-16 (在这个规范里面没有找到E38的,有EXXX 都是3位数。
所以应该是E308-16:规范中关于此填充金属的说明和用途:The nominal composition (wt.%) of this weld metal is 19C r, and 10 Ni. Electrodes of this composition
are most often used to weld base metal of similar
composition such as AIS1 Types3 01,302,304, and3 05.
该焊接金属的公称成分(按重量)是19铬10镍。该成分的焊条主要焊接相同成分的的母材如AISI 标的301,302,304,和305
后面的-16 表示焊接电流DCEP(直流反接)阳极/或AC交流都可以。焊接位置为全部。
补充:Usability Designation -16. The covering for these
electrodes generally contains readily ionizing elements,
such as potassium, in order to stabilize the arc for welding
with ac. Electrode size 5/32 in. (4.0 mm)a nd smaller
may be used in all positions of welding. 这些焊条的药皮通常汗易电离成分,如钠,为了稳定电弧,焊条的尺寸5/32英才(4毫米)和相似的可以用于所有的焊接位置
AWS A5.4美国不锈钢焊条标准
不是E38-16吧,应该是E308-16吧,焊接304的酸性不锈钢焊条,是具体的焊条型号
AWS是美国焊接协会的英文缩写,AWS A5.4 美国焊接协会出的不锈钢焊条标准 。
