Heliarc welding, also known as TIG or GTAW, uses helium gas and an arc generated by a tungsten electrode to fuse metals together. It is a slow and precise process that creates a stronger bond than other welding methods. The use of filler material is often not necessary, making it versatile and durable. Heliarc® welding […]
MIG and TIG welding systems use inert shielding gas for the electrode, but differ in filler materials and electrode wear. MIG is faster and easier to learn, but messier and produces weaker welds. TIG is cleaner and stronger, but more expensive and slower. Both were developed in the 1940s for different industrial uses. A Metal […]
Electroslag welding uses an electric current passed between an electrode and workpiece, with a liquefied slag conducting the current. It is used to join thick steel plates and was patented in 1940 by Robert K Hopkins. The process was refined at the Paton Institute in the USSR and first introduced at the Brussels Fair in […]
Exothermic welding uses a chemical reaction to create a permanent bond between metal components, producing heat and filler metal. It is durable, maintains good electrical conductivity, and can be used with various metals. Safety precautions are necessary due to the high temperatures involved. Exothermic welding is a joining technique used to create a permanent connection […]
Exothermic welding is a durable and efficient joining technique that creates a permanent bond between two metal components using a chemical reaction that generates heat. The process involves heavy metal oxide and a reducing agent that produces heat rapidly, forming a bond shaped by the die. The resulting joint is permanent and maintains good electrical […]
Gas tungsten arc welding uses a tungsten electrode to create a clean weld with less contamination. It is used on thin and non-ferrous metals, requires a shielding gas and filler rod, and produces no smoke. Protective gear is necessary due to the high heat and UV rays. Gas tungsten arc welding is a type of […]
Carbon steel is a family of alloys containing carbon and other elements. Welding is a popular method of joining these materials, with low carbon steel being easy to weld using arc and gas shielded processes. High carbon steel requires pre-heating and post-weld cooling. Different welding methods are used for low carbon steel, including arc and […]
Welding goggles protect eyes from particles and radiation while welding. They must be durable, impact-resistant, filter out harmful radiation, and have a wraparound design. Welding helmets provide complete protection, while light welding goggles are removable but less protective. Without proper eyewear, welders risk eye damage. Welding goggles are protective safety goggles designed to shield the […]
TIG welding requires safety precautions, including proper ventilation and safety equipment. Cleaning the metal is crucial for effective welding, and spot welding can secure pieces together before a full pass. Different weld types require different preparation and execution, and the operator’s movement can vary. TIG, or tungsten inert gas, is a type of welding process […]
Selective soldering is a process used in electronic assembly to solder specific components to a printed circuit board while leaving other areas unaffected. There are several technologies for performing this task, including all-in-one and one-at-a-time methods, with varying levels of precision and speed. The most accurate method is laser welding, but it is slower than […]
Spin welding fuses two parts together through friction-generated heat. One piece is held in place while the other is rotated, creating friction and heat. The right pressure is critical for a strong fusion. Only thermoplastic materials are suitable for this process, and specialized equipment is needed. Spin welding is a process by which two different […]
Stick welding uses a two-piece electrode with a metal alloy core and silicon-based flux to create strong welds. Moisture and incorrect heat settings cause porosity, while spatter indicates excessive heat. Proper handling and direction of the electrode ensure a structurally sound weld. Shielded metal arc welding, also known as stick welding, uses a two-piece electrode […]
Robotic welding is a fully automated process that removes human involvement from handling and welding materials. It is commonly used in the automotive industry and involves programmable robots using arc and spot welding methods. Different types of robots are classified according to their manipulator component, with some using signature image processing to improve efficiency and […]
Robotic welding is a fully automated process that removes human involvement from handling and welding materials. It is commonly used in the automotive industry and involves programmable robots using arc and spot welding.

Different types of welding are available, with the most effective method depending on the materials and skill level. Wire, arc, tig, tungsten gas arc, and spot welding are all options. Safety equipment should always be used. There are several types of welding to choose from. Most commonly, welding involves joining two materials, usually metal, together […]
Forge welding connects metal pieces using heat and force, typically with fire and hammering. It requires concentration, knowledge of metal characteristics, and the use of flux. Thicker metal is easier to weld, and pressure tools vary. Successful forge welding results in a solid object with no cracks or gaps. Forge welding is an old technique […]
Stud welding uses electric current to join metal fasteners to other metal pieces. There are two types: capacitor discharge for small fasteners and arc welding for larger ones. Fasteners are designed for specific welding types. CD welding causes minimal heat damage, while arc welding requires a ceramic ferrule to contain heat. Stud welding is the […]
Stud welding uses electric current to join metal fasteners to other metal pieces. There are two types: capacitor discharge (CD) welding for small fasteners and arc welding for larger ones. Fasteners have specific designs for each type of welding. CD welding causes minimal heat damage and is performed quickly, while arc welding requires a ceramic […]
Welding titanium requires 70% preparation and 30% welding time. Clean material and a controlled atmosphere are crucial. A vacuum chamber may be necessary to prevent oxygen reacting with the heat-affected zone. Welding titanium is expensive and not recommended for beginners.
