Spatter is present in welding. It’s all over welding. But it doesn’t have to be. Spatter costs fabricators millions of dollars every year. Its removal constitutes rework that significantly and negatively impacts productivity. Many fabricators work under the assumption that spatter is a necessary evil, a part of welding. However, this couldn’t be further from […]
Competition amongst manufacturers of welding machines is a wonderful thing. Companies like Miller, Fronius, OTC, Lincoln Electric, and many others are continuously improving their equipment, making it more user-friendly and at a lower cost. We as users benefit from this. However, this has brought about a big problem. And that is the belief that we […]
Maintenance-related problems are responsible for a large portion of bad welds in every day welding. However, these causes go unnoticed and unresolved because they happen slowly over time. A proper preventive maintenance program for welding machines, CNC cutting tables and other industrial equipment is absolutely necessary. Many of the problems related to maintenance that cause […]
In our many years of working in the welding industry we have come across some phenomenal welders. We continue to be impressed by the level of skill of many of these men and women. Unfortunately, many business owners and managers allow this skilled labor to go underutilized. Welder efficiency, which also goes by other names […]
Not all weld discontinuities are weld defects, but all weld defects are discontinuities. Understanding the difference will let you know if you need to scrap a part, repair it or simply add more weld. There are many codes depending on what type of product you are welding on. The codes are used as guidelines by […]
Waveform control is the ability of a welding power source to affect heat input, droplet shape and size, penetration, bead shape and toe wetting by the use of microprocessor controls which manage the welding output. Advances in waveform control technology over the past two decades have provided the ability to weld tough materials successfully. One […]
Galvanizing is the application of a zinc coating to a ferrous material. It is done to prevent, or at the very least delay corrosion. The zinc coating can be applied in many different ways including but not limited to hot-dipping, metal spray and electrodeposition. Similar to galvanized steel is galvanneal steel. Galvanneal is the process […]
Welding is a very complicated industrial process with many different variables. Because of this there are an innumerable amount of problems we can experience when we weld. From porosity and spatter to cracked welds, welding problems cost us a lot of money. In some cases welding problems are severe enough to cause significant delays adding […]
In our last post we explained short circuit transfer; if you missed it you can go back and read Modes of Metal Transfer: Short Circuit. In this post we’ll spend some time going over globular transfer by covering its basics as well as its advantages and limitations. Globular transfer occurs in GMAW and MCAW processes […]
Many fabricators struggle to get a grip on their welding costs. The best they can do is try to find suppliers that will sell them their consumables, gas and other raw materials at a lower price. Those who try to reduce costs by being more efficient soon realize that simply speeding up welding is not […]
