Welding wire is a metal filament supplied in coils, spools, reels or individual rods (rods). It is used as an additive for welding operations in manual (MMA, TIG), automatic (SAW) or semi-automatic (MIG, MAG) mode in shielding gases, as well as for cutting (CUT) steels, non-ferrous metals. When melted during welding, it fills the weld…
The popularity of semi-automatic welding is increasing daily. This trend is not coincidental. Among the most important welding technologies, MIG/MAG is characterized by its high productivity. Master welders appreciate its ability to quickly produce high-quality joints, while beginners are attracted by the automatic wire feeder, which allows them to “get hands-on” more quickly and learn…
Corrosion affects many industries and products, reducing their lifespan and functionality. To address this issue, methods like zinc plating and hot-dip galvanizing were developed to provide steel and iron with protective corrosion-resistant coatings. While zinc plating and galvanizing have similarities, there are key differences between them in terms of process, coating characteristics, and appropriate applications….
TIG (Tungsten Inert Gas) welding, also known as GTAW (Gas Tungsten Arc Welding), is an arc aluminum for beginners process that uses a non-consumable tungsten electrode to produce the weld using a tig torch and welding machine. The weld area is protected from contamination by an inert shielding gas, usually argon or helium. TIG welding…
Underwater welding, also referred to as hyperbaric or wet welding, takes place in aquatic environments under intense water pressure. Steel is the most commonly welded metal due to its strength and ubiquity in marine settings. Wet welding occurs directly in water, while dry hyperbaric welding takes place in sealed, pressurized enclosures. Dry hyperbaric welds often…
Plasma cutting has become widespread due to the precision and quality of the cut, but traditional gas cutting remains utilized in a variety of processes. Oxygen cutting retains prevalent usage for applications necessitating a high degree of mobility and maneuverability, notably for cutting thick steel billets. Both methods confer respective benefits and limitations: material thickness,…
As a professional welder, I often get asked – what is MIG welding? In simple terms, MIG (metal inert gas) welding, also known as GMAW (gas metal arc welding), is a versatile, economical fusion welding process that joins metal pieces together by heating them with an electric arc established between a continuously fed wire electrode…
Table of Contents Introduction Knowing how to properly repair plastic items is an invaluable skill that can save money while reducing environmental waste. As more and more plastic products enter our homes and workplaces, cracks and breaks are inevitable. Rather than throwing these items away and further adding to the plastic pollution crisis, simple repair…
Brazing aluminum is a useful technique for joining aluminum parts. It creates strong, sealed joints by melting and flowing a filler metal into the joint clearance. Here is a step-by-step guide to brazing aluminum. Materials Needed The main materials needed for aluminum brazing include: Type Examples Torch Propane torch, oxy-acetylene torch Brazing rods 4043, 4145,…
Shielded metal arc welding (SMAW), commonly known as stick welding, has been a widely used welding process for decades. Its versatility, cost-effectiveness, and simplicity has made it an indispensable technique across various industries. This article will provide an overview of SMAW, how it works, its applications, equipment needs, and safety precautions. Shielded arc welding is…
