GTAW-FeIV-6FG-12/14-FefS-02/10/12 是什么意思？是我压力容器资格证上的
推荐回答（4个）
GTAW 钨极氩弧焊FeLV 试件材质，奥氏体不锈钢6FG 管板45度固定全位置焊
12/14 试件厚度12mm 外径14mm
FefS 全部钢焊丝02/10/12：02是实芯焊丝的意思，10代表焊接时背面有保护气，12代表直流正接。
焊条电弧焊 SMAWTIG焊 GTAW埋弧焊 SAW熔化极气体保护焊 GMAW药心焊丝电弧焊 FCAW等。
离子弧焊 PA电子束焊 EB激光焊 LB氧乙炔气割 OGC超声波焊 UW冷焊 CW 后面还有好多（字数不够 我留言给你GTAW-氩弧焊.SMAW-手工电弧焊.GMAW.熔化极气体保护焊.PAW等离子弧焊.SAW埋弧焊.FCAW.药芯焊丝下向焊.。
扩展资料：
压力管道GB1级 钢管焊接合格项目的试件位置代号 5G 2G是。不是一个代号，2G 是 试件类别 板材对接焊缝 试件位置为：横焊试件 代号：2G 5G 是 管材对接焊缝 水平固定试件 向上焊 5G。
焊接方法代号：焊条电弧焊SMAW.钨极气体保护焊CTAW.熔化极气体保护焊GMAW.药芯焊丝电弧焊FCAW.埋弧焊SAW.焊接位置代号[url=34/]：板对接焊缝，平焊1G，横焊2G，立焊3G，仰焊4G.管件焊接，水平固定向上焊5G。
水平固定向下焊5GX,45度固定向上焊6G,45度固定向下焊6GX，管板焊接，水平转动焊2FRG，垂直固定平焊2FG，垂直固定仰焊4FG，水平固。
焊接方法代号：焊条电弧焊SMAW；钨极氩弧焊GTAW；焊接位置代号：板材对接；平焊1G、横焊2G、立焊3G、仰焊4G.管件对接：。
特种设备焊接作业项目（GTAW-II-6G-3/60-02和）（SMAW-II-。
GTAW-II-6G-3/60-02氩弧焊，二类材料低合金钢，焊接工件为管子对接，焊丝为实心焊丝，焊接方式为全位置焊即45°固定向上焊，管子规格为Φ60mm，外径为3mm，此证可覆盖氩弧焊>45管子的任意位置焊接（1G、2G、5G）。
SMAW-II-6G3/60-G3J应该是SMAW-II-6G-3/60-F3J才对，手工焊，材料也是二类低合金钢，管子对接试件，规格Φ60*3，全位置焊接。手工焊焊工试件项目表示方法为：① - ② - ③ - ④ / ⑤ - ⑥ - ⑦其中：① 焊接方法代号，耐蚀堆焊代号加：（N及试件母材厚度）。
焊接项目：SMAW-Fe II-6G(K)-3/60-Fef3j和GTAW-Fe II-6G-2/。
第一个，手工电弧焊-II类材质（低合金钢）-45度管（带垫板）-管壁厚度3mm/管径60mm-低氢型焊条第二个
钨极氩弧焊-II类材质（低合金钢）-45度管-管壁厚度2mm/管径60mm-实心焊丝SMAW-Fe II-6G(K)-3/60-Fef3jSMAW焊条电弧焊IIII类钢6G(K)45度管、管 （带垫板）3/60----3mm厚度直径60FeF3J应。
1G代表板对接平焊2G代表板对接横焊3G代表板对接立焊4G代表板对接仰焊5G代表管对接水平固定（俗称全位置焊接）6G代表管对接45°固定后面一个应该是6FG吧——代表管板焊接45°
6G：对接45°全位置（管）G为英语单词Groove的缩写，表示对接焊缝F为英语单词Fillet 的缩写，表示角接焊缝2。
GTAW 钨极氩弧焊
FeLV 试件材质，奥氏体不锈钢
6FG 管板45度固定全位置焊
12/14 试件厚度12mm 外径14mm
FefS 全部钢焊丝
02/10/12：02是实芯焊丝的意思，10代表焊接时背面有保护气，12代表直流正接。
比如我的证书是73的管件。可以焊接压力管道。小管吗？
