Questions regarding the definition of welding position.
Thread Content
GB∕T 3375-1994, Welding Terms, defines the positions of flat welding, side welding, vertical welding, and overhead welding. The definitions of flat welding, groove welding, vertical welding, and overhead welding are also provided. Definitions for \"flat angle welding,\" \"upward angle welding,\" and \"inclined angle welding\" are also provided. In their article \"Some Issues in Implementing the Standards for Welding Procedure Qualification of Steel Pressure Vessels\", teachers Ge Zhaowen and Kang Hongyan state: \"Welding position\": The location where the weld is applied. “\"Test specimen location\": The spatial position where the test specimen is located. “Whether it is a butt weld or a fillet weld, there are only four welding positions: flat welding, vertical welding, overhead welding, and submerged welding. (In my opinion, the \"welding positions\" mentioned here should be consistent with those specified in WPS and PQR in standard 4708.) ) Clearly, the terms \"welding position\" as used by teachers Ge Zhaowen and Kang Hongyan differ from those in GB∕T 3375-1994. There are no such welding positions as \"flat angle welding,\" \"upward angle welding,\" \"inclined welding.\" The terms \"flat welding position\" and \"flat welding\" are not the same concept either. If it is said that there are only four welding positions: butt welding, fillet welding, vertical welding, and overhead welding, then the so-called \"butt welding position, fillet welding position, vertical welding position, and overhead welding position\" as defined in GB/T 3375-1994 refer to the position of the test piece. If \"corner welding\", \"overhead corner welding\", and \"inclined welding\" are not recognized as types of welding positions within the scope of process evaluation, then what are they? Within what scope will it be recognized?
Everyone is very low-key; they’re not as fond of showing off as I am. This issue also troubles me, and I sincerely hope to get everyone’s help. Thank you!
I’ll take the lead; I hope everyone will share their opinions
Lift it up again; moderators, please help and raise it a bit.
JB/T4708 -2000 does not provide detailed information on the welding positions; in my opinion, what is stated in ASME IX makes more sense. Welding test positions: 1G, 2G, 3G, 4G, 5G, 6G. Welding product positions: F (flat), H (horizontal), V (vertical), O (upside down). Upon closer consideration, welded products exist in just four basic positions: F (flat), H (horizontal), V (vertical), and O (upright). However, the welding test positions are different; for example, 5G includes the three positions of F, V, and O. Therefore, in my opinion, PQR should specify the welding test positions: 1G, 2G, 3G, 4G, 5G, 6G, while WPS should indicate the welding product positions: F (flat), H (horizontal), V (vertical), O (upside down)
As for the welding positions for a single finger, I believe there are 4 types: horizontal, vertical, upright, and inverted”
