For thicker joints, the edge of each member of the joint must be prepared to a particular geometry to provide accessibility for welding and to ensure the desired weld soundness and strength. The opening or gap at the root of the joint and the included angle of the groove should be selected to require the least weld metal
Weld preparation may be carried out by thermal cutting or machining. Seam edges (groove faces) prepared by thermal cutting shall be finished by machining (e.g. grinding) if a detrimental effect on the welded joint as a result of the cutting operation cannot be ruled out. Welding edges of steel castings and for- gings shall
The selection of the proper joint type depends on a number of factors, such as joint thickness and material, desired physical properties in the finished joint, size of the pieces being welded, accessibility of the joint, fit-up obtainable, available edge preparation equipment, number of pieces to be welded, and specifications of
module in the plant is the edge preparation machine, followed by a rack of linear flow splitting modules. At the third position, the racks of the roll forming are attached. After them, both the. HSC of sheet metal and the laser welding are arranged. Shearing to the defined work piece length finishes the manufacturing process.
21 Apr 2009 While designers need some basic knowledge of welding processes, equipment, materials, and techniques, their main interest is in how to transfer forces through welded joints most effectively and efficiently. Proper joint design is the key to good weld design. The loads in a welded-steel design are

prepared primarily for the fabricator's engineering and drafting personnel. The welding engineering standards typically include: (a) Illustrated profiles of each typical joint intended for use, showing: (i) The type of joint (eg, butt, lap, tee, corner, edge);. (ii) The type of weld;. (iii) The geometry of the preparation and fit-up;.
Joint Types. The American Welding Society defines a joint as. “the manner in which materials fit together." As shown in. Figure 6-1, there are five basic types of weld joints: • Butt joint. • T-joint. • Lap joint. • Corner joint. • Edge joint. Joint Preparation. Weld joints may be initially prepared in a number of ways. These include:.
