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
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
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
Oxygen is an important element of atmosphere. We breath oxygen and exhales carbon dioxide. In addition to that oxygen is a required element for combustion. But the air we breath and the oxygen we use in industry to burn is not the same in proportion. The air contains 21% oxygen only. But the industrial gas … Read more
Welding evolves eyes to concentrate on weld pool while making weld. It is a risky and hazardous work as you eyes may exposed to the ultraviolet radiation (UV) or infrared rays (IR). These rays are very harmful for eyes and can damage eyes gradually. Moreover, these rays are not the only culprit in welding profession … Read more
Mig and spot are two popular welding processes for industrial use. Both welding processes are effective for metal joint work. But what are the differences? A comparison of Mig welding vs spot welding can clear the issue. Mig and Spot welding are unique in their process, shielding gas usage, strength, safety and ease of learning. … Read more
Spattering problems may occur in welding for various reasons, such as incompatible welding metals, dirt or contaminated materials, inappropriate welder voltage settings, wrong welding technique, incorrect welding gas, welding equipment problems, incorrect welding speed, improper wire feed speed, improper gas flow rate etc. What Does Spatter Means In Welding? Spatter in welding refers to the … Read more
A regular outlet is a 15-amp outlet that you will normally see in any household and workplace. It can come as duplex receptacles. It is recommended to plug in small appliances and lamps. Have you been wondered whether you can plug your welder into your household outlet? The answer is Yes, you can plug your … Read more
Filler metals are metals incorporated in making joints through soldering, brazing, and welding. There is a significant influence in filler metal compositions by corrosion resistance of alloy 800H, mechanical characteristics, and microstructure. Generally, filler metals include Alloy 309, Inconel 82, and Inconel 625. Moreover, filler metals provide in-depth details about the product’s usability and specifications, … Read more
