Galvanized steel can be more difficult to spot weld than uncoated metals, but it’s definitely possible and commonly done. Before we get into the unique considerations of welding this particular metal, here’s a brief refresher on spot welding and galvanization.  ..read more

Lap seam welding is a type of resistance welding, also known as electrical resistance welding (ERW). Unlike arc welding, which uses gas, resistance welding uses a strong electric current to join two metal parts. The current heats the metal parts at the welding joint, causing them to melt and forge together. In seam welding specifically, the weld wheels (electrodes) apply the force and deliver the necessary current. After the weld absorbs heat energy from the molten weld joint, a weld nugget forms at the point of solidification. Applying pressure before, during, and after passing the electric c ..read more

You may have heard of resistance welding, but have you heard of resistance brazing? In this article, we explain what this technique is, how it is performed, and what the advantages are in using it ..read more

In a study of common welding defects and causes of poor weld quality , the most common factor by far was fixture errors, but issues can arise from the power supply, part geometry, and a number of other variables. Some of the more common ones are listed below ..read more

In all walks of life, using the correct tool for the job is an essential part of making your work easier, more efficient, and more effective. Welding is no exception to this rule, as evidenced by the abundance of forms and techniques involved in the process. While many types of welding appear similar on the surface, they vary widely in the processes they use to achieve fusion and the results they can produce. Today, we’ll talk about MFDC welding, and the potential benefits it provides to companies who choose to implement MFDC welding technology ..read more

Resistance welding, while being a subset of welding practices itself, is a fairly broad category. Many different variations of resistance welding are needed to apply the correct forces to the correct places in different situations. One of the most common variations of resistance welding used in manufacturing facilities is projection welding. We thought it might be useful to give some background information on what the process of projection welding entails, how it is used, and why. (Don’t worry, we’ve included pictures ..read more

In resistance spot welding, “weld nuggets” are areas on the base material that are formed where the two metals are joined. The intense heat and sometimes low force of the welding process usually causes a depression or dimple.  There may be some material build-up around the edge of the weld site.  Analyzing and measuring nuggets after a weld is essential to keeping equipment operating in peak condition. They are useful in determining if the welding process is experiencing any irregularities and for determining the strength of the weld itself. The process for measuring nuggets is stand ..read more
