The word ‘spatter’ is familiar to all welders, just as it is frustrating. If you’ve never found yourself glaring at tiny molten metal blobs around your weld after a harrowing welding experience, then you are yet to be introduced to the bare skeletons. Should these spatters fall on you, they will burn through to the […]

If you have worked with aluminum before, you probably understand its challenges when handled the wrong way. Unlike steel and other metals, aluminum needs special treatment before you start the welding process. Step-by-Step Cleaning Procedure for Aluminum for Welding Dirt and other impurities affect the quality of a weld in all metals, and aluminum is […]

Wrought iron is typically used for fences, handrails, and other home metal ornamentation. It does have durability, but if excess pressure is applied, it can break because it is made from cast metal, which is porous. The porousness of the metal can determine its overall strength. Aluminum is an example of a metal that is […]

Becoming an approved welder increases your opportunities of getting a job offer to work with a top employer. But first, you have to take and pass the welding test. Your knowledge of welding theory and command of hands-on practical expertise in your welding specialty is tested. Although there’s nothing that can replace assiduous study for […]

In past decades, stick welders did not have much information about gases with regards to welding. This whole concept changed with the invention of TIG and MIG welding machines and their constant rise in usage. Gas is now considered a common commodity in most welding workshops. But how much does welding gas cost? If you’re […]

Among the essential items in a welder’s protective equipment kit is a shade. Having the appropriate shade lens will protect a welder from radiations, spatters, and sparks produced during welding. According to the US Consumer Product Safety Commission report, over 10,000 eye injury cases are reported in the USA annually. A large number of these […]

An undercut is a surface and subsurface defect resulting from grooves within the parent metal area. Like all other defects, instead of improving the joint strength, it introduces weak points that often propagate structural failure. At the microscale level, the micro-cracks are observed within the defective surface, meaning material failure is inevitable if not remedied […]

There are a variety of welding processes that use different equipment. While ‘tack welding’ might seem like just one process among many, it is actually a specific application of any welding process. Without tacking, as it is commonly called, welding accurately and to proper specifications would be impossible. Tacking is essential for any welder, but […]

You are often not consciously thinking about the numbers on the side of a rod while you are actually welding. When you’re holding that stinger and laying beads into a joint, aside from your overall welding skill and knowledge of the machine, there are factors that determine the quality of the weld. It starts with […]

We all know welding includes hot hot heat, but how hot is the welding arc, really? On average, a welding arc is between 6500 and 10,000˙F. But a plasma arc can be up to 50,000˙F! Welding is a curious trade. Whereas the work involved with trades such as masonry or carpentry can all be observed […]
