Butt welded joints. A Butt Weld is a circumferential butt welded joint, and the most common type of joint employed in the fabrication of welded pipe systems. A butt joint is the most universally used method of joining pipe to itself, fittings, flanges, Valves, and other equipment.
Corner Welding Joint. Corner Joint Being one of the most popular welds in the sheet metal industry the Corner welding joint is used on the outer edge of the piece. This weld is a type of joint that comes together at right angles between two metal parts to form an L.
A lap joint is the joint between two pieces of metal in which the edges or ends are overlapped and fastened together to produce a continuous or flush surface. Several types of lap joint techniques exist and are employed depending on the type of materials, shape, and thickness of the parts or the application of the jointed object.
Whereas a square joint consists of welding two faces parallel to each other, a lap joint is used to weld two perpendicular faces. This is referred to as a fillet weld. When welding a lap joint, it is also possible to weld the overlapping seam on the opposite side of the workpiece to improve the strength.
In welding, tee joints are used to weld two plates or sections with surfaces located approximately 90 degrees to each other at the joint, but the surface of one plate or section is not in the same plane as the end of the other surface. A plain tee joint welded from both sides is shown in [view B, figure 6-22].
tig welding t joints Are you drawing a puddle in less than 3-4 sec? I always set my amps at the amount it takes to draw a puddle in 3 sec or less. Then i back of to working amps and i start added rod right when that puddle is liquid. The amps depend on ur machine and technique. Ive always went by puddle forming time.
