The Secret to Welding Steel to Aluminum

Not all metals are easy to weld together. Some metals have different physical and chemical properties that make them incompatible for welding. One of the most challenging combinations of metals to weld is steel and aluminum. Steel and aluminum are very different metals with respect to their melting points, thermal conductivities, expansion coefficients, and solubilities….

What Are the Different Types of Joints in Welding?

When it comes to welding, one of the most critical aspects to understand is the different types of joints in welding that are utilized to create strong and durable welded structures. The joint is where two pieces of metal are fused together through the welding process. Selecting and properly preparing the right type of joint…

What is the Difference Between AC and DC Welding?

AC and DC welding are two different types of welding currents that affect how the arc is created and maintained between the electrode and the workpiece. AC stands for alternating current, which changes its direction periodically. DC stands for direct current, which flows in one direction only. The choice of welding current can have a…

Flux Core Welding Polarity Demystified: The Key to Perfect Welds Revealed!

Flux core welding utilizes consumable electrode wires filled with flux to provide shielding for the weld pool. Polarity, or the direction of current flow, is an important but often overlooked parameter when flux core welding. The selection of direct current electrode positive (DCEP), sometimes referred to as reverse polarity welding, direct current electrode negative (DCEN),…
