Welding Positions Illustrations of Horizontal Flat
The welding rod, which is melted into the welded joint, plays an important part in the quality of the finished weld. Good welding rods are designed to permit free flowing metal which will unite readily with the base metal to produce sound, clean welds of the correct composition.... Move the flame away from the joint and feed about 1/2 in. to 3/4 in. of solder into the joint. The solder will flow into all areas of a properly cleaned and fluxed joint. Then to make sure the joint is completely filled, run the tip of the solder quickly around the seam. It's easier to reach around the backside of the joint if you bend a hook on the end of the solder before you start. If the

Forgetting to grind the joint after oxyfuel or plasma cutting Both the oxyfuel and plasma cutting processes add a layer of oxide to the cut edge. This oxide layer must be removed prior to welding, as the oxide often has a higher melting point than the base metal.

Steel pipe joints commonly are welded using an open-root joint geometry (see Figure 1). You can use gas tungsten arc welding (GTAW), gas metal arc welding (GMAW) in short-circuit mode, or shielded metal arc welding (SMAW) to weld the root pass. You then can fill the joint using SMAW or GTAW, although you also can use GMAW in spray transfer mode if the pipe joint can be welded in the flat how to change the backgroud on a second desktop 13/10/2007 · We weld rings of tubing on elec. motor end bells so we can chuck their irregular shape in a lathe to bore and bush the bearing fit.

How To Cut A Welded Joint

A butt joint is a joint that is used when two pieces of metal are to be welded together side by side. This type of weld is probably the easiest type to do as it consists of two flat pieces that are attached parallel to each other in a side-by-side fashion.

  • There are five common types of weld joints used in all types of welding: corner joints, edge joints, lap joints, tee joints, and butt joints. Corner Joint – When two pieces are perpendicular to each other and one piece’s edge meets the end of the other piece’s surface, it is referred to as a corner joint.
  • When a welder can only access one side of the joint to be welded, preparing the parts with open square edges does not generally enable the weld metal to penetrate completely when wall thicknesses are more than 3mm (.787”). Therefore, a bevel must be made, so that the welder can make a root pass at the bottom of the joint, which will then be filled by one or more additional passes.
  • On corner joints, the double fillet can actually produce a full-penetration weld joint. The use of the fillet for making all five of the basic joints is shown in the figure below. Fillet welds are also used in conjunction with groove welds, particularly for corner and tee joints.
  • A welded joint formed by pressure welding (Figure 4,b) does not have a zone containing weld metal or a fusion zone. It consists of a joint zone, in which interatomic links have been formed between the joined components, a mechanically affected zone, and a zone of the adjacent base metal.
