If you have ever wondered what is the purpose of welding flux, keep in mind that its main function is to take off any oxidized metal from the material to be welded. Also, it is used to protect the heated metal from reacting with atmospheric air which can lead to further oxidation. The welding flux achieves this by forming a gaseous shield around the welded part. Flux is a … [Read more...] about What is the purpose of welding flux?

What is straight polarity in welding? Usually, straight polarity in welding occurs when the electrode is made negative and the base plate is made positive, causing the electrons to flow from the electrode tip to the base plate. Types of polarity In welding, there are three known types of polarity: 1) direct current straight polarity, 2) direct current reverse polarity, … [Read more...] about What is straight polarity in welding?

Sound waves play a crucial role in how ultrasonic welding works. Ultrasonic welding utilizes ultrasonic vibrations at a high frequency of about 20kHz to 40kHz. This generates heat energy that is used to melt the pieces and weld plastic materials together. Once cooled, the melted pieces form a strong and solid weld. What is ultrasonic welding? Ultrasonic welding (USW) … [Read more...] about How ultrasonic welding works

How does thermite welding work in practical terms? Thermite welding can be defined as a welding method where heat is created during a chemical reaction, and this chemical reaction takes place as a result of the difference of free energy between aluminum and metal oxide. The chemical reaction which generates the heat is described as aluminothermic reaction. This reaction … [Read more...] about How does thermite welding work?

Basically, X-ray welding is an experimental welding procedure that generates the thermal energy needed to seal materials by using a powerful X-ray source. This procedure used in this type of welding is quite similar to that used in laser beam welding and electron beam welding. X-ray welding is one of the newest advances in welding technology. In this type of welding, thermal … [Read more...] about What is x-ray welding?

If you have been to a welding shop and seen welding machines unused at a corner, you might be wondering: why are welding carts angled?

MMA welding is a fabrication procedure wherein various pieces are fused by heat and pressure. Welding is mostly done on metal or thermoplastic pieces but can also be applied to wood, and the finished product is known as a weldment. Welding has similarities to soldering and brazing, but their processes do not melt their base metals. Yet welding does melt the base metals … [Read more...] about What is MMA welding?

Most laypeople may already know that welding involves heat of some kind, but specifically: how hot is a welding arc? Welding is defined as a process done to metals that involves softening the pieces with heat and applying pressure, thus fusing them. Welding is also an unusual trade compared to other tradecrafts like carpentry or masonry, wherein they are observable and … [Read more...] about How hot is a welding arc?

Are you interested in really knowing what is tack welding? As it turns out, the whole process is quite interesting. People familiar with the various welding procedures dismiss tack welding as unimportant and temporary because, in a way, it is. However, as professional welders attest, tack welding is as significant as other welding processes and provides many practical … [Read more...] about What is tack welding?
