ISO 15614-1 8.4.3For level 2: The range of qualification for the type of welded joints is as used in the welding procedure test subject to limitations given in other clauses (e.g. thickness) and additionally: a) butt welds qualify full and partial penetration butt welds and fillet welds, while fillet weld tests are required where T-joints are performed by fillet welds or partial penetration butt welds in the predominant form of welded connections in relation to the design and production welding;b) full penetration butt welds qualify full and partial penetration butt welds and fillet welds in any type of joints; c) butt joints in pipe qualify branch connections with an angle Į 60° (see Figure 4 for Į) ; d) butt welds in T-joints with full penetration qualify full and partial penetration butt welds in T-joints and fillet welds but not vice versa;e) fillet welds qualify fillet welding only; f) welds made from one side without backing qualify welds made from both sides and welds with backing; g) welds made with backing qualify welds made from both sides; h) welds made from both sides without removing the root qualify welds made from both sides with removing the root (except thermal gouging); i) welds made from both sides with or without gouging qualify welds made from one side with backing; j) when impact or hardness requirements apply, it is not permitted to change a multi-run deposit into a single run deposit (or single run on each side) or vice versa for a given process; k) build-up welding. Build up is qualified by butt weld test piece;l) buttering shall be performed by a separate test piece in combination with the butt weld. 是否可以简单理解为a)对接覆盖对接和角接；b)管对接覆盖支管；c)T接覆盖T接；请问，1）板对接可以覆盖管对接吗，如果可以，厚度范围如何确定2）同上，管对接可以覆盖板对接吗3）管板焊接工艺如何确定？谢谢
