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….
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…
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…
The wind is blowing, and you are trying to weld the axle on your trailer, but you can see the weld puddle being affected as the shielding gas is blown away, causing you to end up with weak and untenable welds. Such conditions can be incredibly frustrating, but a change in wire to a self-shielding…
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),…
After reading glowing reviews from welders using Lincoln Electric FC90 flux core wire feed welder for small jobs and repairs, we decided to take a closer look At the Lincoln FC90 and see if it was the right flux core welder for small workshops or home use. We were eager to see how this this…
A common question often asked by new welders is new welders have questions about whether or not it requires a shielding gas. The short answer is – it depends! Flux core welding refers to a process that uses a wire electrode filled with flux. This flux protects the weld from contamination during welding. However, there are two main…
Flux core welding for titanium has some advantages and disadvantages that welders should consider before choosing this method for their welding process. Below we will discuss the pros and cons of flux core welding for titanium and how they affect the welding process’s quality, efficiency, and safety. By going through this article, you should better…
In simple terms you can’t use flux core welding method with aluminum so flux core wire for welding aluminum doesn’t exist and you will waste a lot of effort trying to find or weld aluminum using the flux core method. It is easy to see why this myth perpetuates. The flux core method holds a…
Flux core welding can be a very effective method for welding stainless steel. However, the quality of the weld can be adversely affected unless you select the best flux core wire for welding stainless steel material. Below, we will explain the key factors you need to consider when choosing flux core wire for welding stainless…
