Welding Basics

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…

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…

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 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…

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…

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…

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…

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…

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…

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…

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…

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…

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…

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…

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,…
