Thread Content
On the SEAM PLAN diagram in the equipment drawings, what do L.W.L and C.W.L mean? ? In the local C.W.L detail drawings, there is also the abbreviation G.T.A.W. What do they mean respectively? ? Hope experts can give some advice!
L.W.L Longitudinal Weld Line C.W.L Circumferential Weld Line G.T.A.W. (Tungsten Inert Gas Arc Welding)
Girth weld line, longitudinal weld line. The first two relate to G.T.A.W. (Gas Tungsten Arc Welding); I’ve learned about this, haha
