what is the difference between seam welding and spot welding?
431028
Unlike a spot weld that uses a single point electrode, a seam weld uses a rotating wheel electrode that produces a rolling resistance weld. This process is most often used to join two sheets of metal. MIG and TIG welders can be used to do seam welding.

In short, welding is a technique that joins metals by melting the base metal and causing fusion, while brazing joins metals by melting and flowing a filler metal into the joint. In brazing and welding, fabricators add a filler metal into the joint.

The main difference is the material that the 'tip' of the spark plug is made of - normal ones are usually copper, whereas the other two have tips made out of platinum or iridium. ... On an engine that has been modified with higher compression or more boost, it might be worth springing for platinum or iridium plugs.

Tee welding joints are formed when two members intersect at a 90° angle which makes the edges come together in the center of a plate or component. Tee Joints are considered a type of fillet weld, and can also be made when a pipe or tube is welded onto a base plate.

The clone tool option replaces the area with an exact replica of the area. The Heal tool gives you a more blended option. Depending on what you are using the Spot Removal Tool for, one or the other may work better. If one is not working well for your circumstance, switch over and try the other.

The single primary difference is the heat source whereby arc welding is heated using an electric arc at 10,000-20,000°F and oxy-fuel welding uses a flame as the heat running around 4000-6300°F. ... On the other hand, certain things are far more easier to weld using the gas method than an arc method.

Groove welds are stronger than fillet welds. In general, basic welding positions consist of 4 types namely flat position, horizontal position, vertical position, and overhead position. ... – 3G (Vertical Welding Position). – 4G (Welding Position Overhead or Overhead).

Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt and join.

There are five types of joints referred to by the American Welding Society: butt, corner, edge, lap, and tee. These configurations may have various configurations at the joint where actual welding can occur.

The main difference between the two is with the recommended welding polarity. ... AC welding output. In most cases, DC is the preferred welding polarity. Whether it is DC+ (electrode positive or “reverse”) polarity or DC- (electrode negative or “straight”) polarity, DC produces smoother welding output than AC.

The difference between the two is the way the arc is used. MIG (metal inert gas) welding uses a feed wire that constantly moves through the gun to create the spark, then melts to form the weld. TIG (tungsten inert gas) welding uses long rods to fuse two metals directly together.

The difference is that flux cored electrodes are tubular, or a hollow tube with flux in the center. MIG welding electrodes are solid metal. Flux cored electrodes come in standard sizes. Some are the same size as most MIG welding electrodes but others are comparable to the thickness of a stick welding electrode.

The main difference between these is of commitment. In Spot Instance there is no commitment. As soon as the Bid price exceeds Spot price, a user gets the Instance. In an On-demand Instance, a user has to pay the On-demand rate specified by Amazon.

The main difference between the process of welding and soldering is melting since soldering involves heating of the metal to be bonded rather than melting. In welding, fabricators melt the base metal, causing fusion. Brazing, on the other hand, combines metals by melting and flowing filler metal right into its joint.

Smoke and Spatter are reduced when pipe joints are welded by means of the Surface Tension Transfer (STT®) process. In open root pass pipe welding, the STT process controls the wave form of the welidng current for excellent penetration control, fusion, and back bead.

The difference in the basic manufacturing method is obvious from the names. Seamless tube is extruded and drawn from a billet while welded tube is produced from a strip that is roll formed and welded to produce a tube. ... Most tubing (seamless and welded) is drawn to produce final dimensional tolerances.
