This element is only shown when the weld is not to be full penetration and represents the desired penetration depth of the weld. John, Not trying to be a pain or funny, notice the wording you used: It doesn't matter how you get to the joint configuration i. However, it is an interesting conversation and it is relevant to much of the work we inspect here in the U. But if it were my job I would now head to the engineer through an RFI. I have no argument with your choice of weld details extracted from A2.
Full penetration Weld and Weld symbol
Since a WPS can contain all of the details applicable to a specific joint, a welding symbol composed of an arrow, reference line, tail and applicable WPS designation would be sufficient to completely specify the welding of the joint. So there you have it… 2 examples of full penetration welds and 1 example of a partial penetration weld. Obviously that is not the case as it is common to weld t-joints with groove welds. A second way to specify complete joint penetration is to include a single groove-weld symbol or double groove-weld symbols must be the same weld symbol on both sides of the reference line , without any dimensions to indicate depth of bevel or weld size. The height of the reinforcement, if critical, is indicated to the left of the melt-thru symbol, which is placed across the reference line from the basic weld symbol. The thicker the plates, the greater the gap. The fillet weld symbol is a right triangle placed on the reference line with the perpendicular leg always on the left.
Weld Symbols - Australian Welding Institute
I can't tell you how many arguments I've ended with that very statement. Help with welding symbols required GRoberts Metallurgy has a strong influence on the ability to weld different types of steel. I would direct any who would be so inclined to review this thread: When the angle between the fusion faces is such that the identification of the weld type and, hence, proper weld symbol is in question, the detail of the desired joint and weld configuration shall be shown on the drawing with all necessary dimensions see Figure
Help with welding symbols required I hate to recount how many times I've seen engineers and designers try to "force" a standard welding symbol to define a weld that simply couldn't be described by a standard welding symbol. However, when the dihedral angle is less than 60 degrees, the joint more closely resembles the conditions of a partial joint penetration groove weld where fusion to the root is not necessarily expected, hence the Z-loss must be accounted for. It does not address design nor workmanship requirements. The arrow points toward the piece that is to be chamfered. Or if you don't have a Miller account, create one today. Visual inspection can be used to ensure proper weld size has been obtained. Plug welds and slot welds are used join overlapping members, one of which has holes round for plug welds, elongated for slot welds in it.
