So, knowing arc wedding basics is important to working on precision arc welding projects. In this guide, we will detail the basic principle of arc welding. If you are finding a comprehensive guide about arc welding then … Read more
In welding, a set of basic weld symbols are used to describe the information of the size, quality, type of weld, starting and finishing. American National Standards Institute (ANSI) and the American Welding Society (AWS) have listed and published a set of welding symbol elements that are necessary to recognize. Fabricators and welding engineers need … Read more
There can be various types of welding position. Some of them are challenging welding position and some are easy. Welding position is simply the angle of joining metal. A metal can be welded from different angles and typically 4 basic welding positions are used in most of the cases. They are Horizontal, Vertical, Flat & … Read more
Knowing the basics of resistance welding is important to make welding more precise and flawless. Resistance welding is mostly used in the automotive industry. The precision welding required to weld on small items, especially nuts and bolts, is possible through resistance welding. There are several types of resistance welding based on functionality and weld requirements. … Read more
There are several types of welding joints, each designed to meet specific requirements and suit different applications in various industries. Many people mistake weld types as weld joints but both are different. There are a number of differences between weld type and weld joints. So, it is important to distinguish between weld types and weld … Read more
Duty cycle is a measurement of running time of a welder machine. It simply measures how long a welder machine will run continuously without stopping in a selected timeframe. It is important to consider duty cycle while choosing a welder machine. In this guide we will delve into duty cycle, how it works and how … Read more
Flux core wire, mostly referred to as FCW, is commonly used for repairing auto body projects, but why not use the stick welding when you don’t want to use any gas and wire feeders? The only but most important demerit of a stick electrode is you have to change the electrode frequently. That’s a big loss … Read more
When we hear about welding, what comes to our mind first is the flames, electric arc and weld seam. But if I tell you that there are a type of welding which doesn’t require any flame, arc or heat to join metals! I know you got surprised hearing that. But it really exists and in … Read more
Welding is the cosmic union of metals, a fiery embrace that transforms separate pieces into a singular, unbreakable bond. It involves joining two or more pieces of metal simply by melting them through applying heat and in turn fusing them together. This heat is generated by an electric arc, gas flame, or laser. After melting … Read more
Polarity is the direction at which electric arc or current would flow. If current flow from electrode to workpiece, then it is a DCEN or straight polarity. And if the current moves toward electrode from workpiece, then it is called DCEP or reverse polarity. In other words, DCEN is a settings where electrode is connected … Read more
All welds contain discontinuities. Even an expert welder can make mistake while welding. But the discontinuities become defect when it crosses the standard acceptance level. A flaw or discontinuities can be accepted or rejected based on welding prequalified standards. These standards are set by expert inspectors or few welding quality control organizations like AWS (American … Read more
Welding qualification involves various testing procedures to ensure that the welded joints meet specified standards and requirements like AWS D1.1 or ASME Section IX. The procedures can be either destructive or non-destructive in nature. These procedures are crucial to guarantee the integrity and reliability of the welds. DIY’s do not need to undergo these tests … Read more
Within the realm of welding, the linchpin of any manufacturing process is Quality Control (QC), playing a central role in achieving sound and reliable welds. The collaboration between Quality Assurance (QA) and QC is essential, not only for meeting specifications but also for minimizing rework and ensuring the longevity of the final product Quality Assurance: … Read more
Mig welding is an excellent process for joining metals with continuously feeding wire electrode. Mig welding can make a perfect and long-lasting joint between carbon and mild steel turbo pipe. Besides, the versatility of MIG welding for turbo piping makes the mig welding popular among welders. In this guide, we will talk on whether you … Read more
Pre-qualified welding procedure specifications (WPS) are standardized welding procedures that have been established and qualified in advance by recognized welding authorities or standards organizations. These pre-qualified procedures are based on extensive testing and documentation to ensure that they meet certain criteria for weld quality, strength, and reliability. The purpose of pre-qualification is to streamline the … Read more
