The calculation formula for the geometry of the joint when pouring is an important part of ensuring the integrity of the joint. In metallurgy and welding, it is necessary to understand the geometry of the joint in order to calculate the area and dimensions of the weld and form the correct material mix. There are three basic types of joint geometry - lap joints, butt joints, and corner joints.
1. Lap joints
This type of joint is formed by overlapping two plates, the melting point of which can be the same or different. The formula for calculating the lap joint geometry is F = W × T + 1.5D, where W is the width of the plate, T is the thickness and D is the diameter of the fillet weld. The thickness and diameter of the fillet weld depend on the type of material and the welding process.
2. Butt joints
In this type of joint, two plates of metals are butted up against each other and welded. The calculation formula for the butt joint geometry is B = Z × C + K, where Z is the width of the plate, C is the thickness and K is the thickness of the preparation, which should be equal to the combined plate thickness. K should also be greater than or equal to two times the thickness of the weld metal.
3. Corner joints
A corner joint is formed when two plates intersect at an angle and are then welded. The calculation formula for the corner joint geometry is M = A × P × 2 + H, where A is the length of one side of the joint, P is the length of the other side and H is the thickness of the weld metal.
These three formulas provide the basic geometry information and parameters for the welding process. These formulas provide the necessary information and parameters for the welding process including the size and shape of the joint, the number and characteristics of the welds and other critical factors. Understanding the geometry of the joint and the corresponding formulas is a key part of successful welding and metallurgy.
