2023年7月7日 · Another similar welding position is 2G, which means a horizontal welding position for grooves not for fillet welds. In this position, the weld axis remains horizontal and the weld is facing the vertical plane.

2024年1月31日 · It is a 5/16" single bevel, and a 1/2" cover fillet. Both materials are carbon steel pipe, the ring being A106B and the pipe being similar to A53B. Customers typically ask for B31.3 or B31.1. I know if I qualify welders for semi-auto welding I just need to perform a 2G weld test and that covers all the jobs we do.

2018年3月15日 · Welder Performance Qualification (WPQ) as per ASME SEC IX As the quality of weld depends upon skill of the welder, it does require qualifying a welder by testing. Testing is to demonstrate the welder ability to produce a Sound weld joint; these tests are qualitative in nature.

2022年9月3日 · Some welding engineers specify welding positions on the WPS format as 1G, 2G, etc. This is not appropriate. Instead, the positions should be described as flat, horizontal, etc. Although, weld position for procedure qualification has become a moot point, after the 2019 edition of Section IX onwards.

2024年1月31日 · I was posed the question as to whether or not 2G Rotated could be used during welder performance qualifications and still be ASME Section IX compliant. This would make it easier for welders to pass, however we do non-rotated 2G welds.

2022年1月11日 · For plate, the Welding Positions (Shown in the below picture) specified in ASME Section IX, or AWS D1.1 are: 1G Welding Position , where ‘1’ means Flat Welding Position. 2G Welding Position , where ‘2’ means Horizontal Welding Position.

2022年6月14日 · 目前国际上最常用的焊接位置符号有两个标准，一个是美标ASME IX和AWS A3.0, 另一个是国际标准ISO6947，由于不同标准的焊接位置符号内容多易混淆，所以总结如下图表来帮助大家进行更好的理解。 美标AWS A3.0或ASME IX焊接位置示意图. 注：1G-平焊 2G-横焊 3G-立焊 4G-仰焊 5G-（管水平固定） 总的来说，美标与国际标准焊接位置符号还是有很大差别，只有我们认真仔细领会，灵活应用，才容易理解与熟练掌握图纸与标准的焊接位置符号语 …

2002年12月12日 · In your case even if you have qualified on 1G with or without impact testing on PQR, it would surely qualify for 2G position as per ASME Section IX. So you should be able to qualify a welder in 2G position.

Please note that ASME section IX has mentioned four test positions for plate groove welding i.e. 1G, 2G, 3G, and 4G. Whereas, for pipe groove welding, the test positions are 1G, 2G, 5G, and 6G. There are no 3G and 4G positions for pipe groove welding.

2008年9月21日 · I am writing a WPS according to ASME IX with below welding variables: - Welding process: FCAW - Position of Groove in PQR: 2G - Tests for PQR: Tension Test, Guided bend Test, NOTCH TOUGHNESS TEST, Macro Examination. => in WPS: Position Qualified: Groove: 1G, 2G, 4G; Fillet: 1F, 2F, 4F. Am I right? Please advise me if something's wrong.
