Laser beam welding fuses metal using a high-temperature laser, with two types of welding equipment available. The technique is popular in the manufacture of airplanes, automobiles, and spacecraft, but has some disadvantages. Laser welders emit a dense beam of photons to rapidly heat and fuse metals, with solid-state and gas laser welders used. The technique […]
Welding is a dangerous job due to risks such as asphyxiation, skin and eye damage, fires, and long-term effects of fumes. Sparks and arcs pose a risk, but equipment can reduce exposure. Carcinogenic or toxic chemicals are the leading cause of health problems, and welding produces dangerous gases. Proper equipment, safe materials, and common sense […]
Microwelding is the precise placement of connective metals and energy to form welds less than 100 micrometres wide. Micro resistance welding is used to join flat sheets, micro flash welding is for small butt joints, micro arc welding is for any shape, and laser microwelding is used in automated industrial environments. The term “microwelding” refers […]
TIG welding uses a tungsten electrode to create an arc between metals, with shielding gas to prevent oxidation. Argon is the preferred gas and steel and aluminum are commonly used. Different joint types can be welded, with a filler rod used for heavy metals. Tungsten Inert Gas (TIG) welding is the process of mixing reactive […]
Cold welding is a bonding process that uses pressure instead of heat to combine two metals, but not all metals are suitable. It is best for objects in space due to its limitations. Cold welding has been around for thousands of years and can be performed with less force or by raising the surface temperature. […]
Projection welding uses surface protrusions on one or both sheets to concentrate welding energy, allowing for closer weld gaps on thicker materials. It is commonly used in the automotive industry for connecting studs and nuts to sheet metal assemblies. The process is suitable for low carbon steel, stainless steel, and aluminum, with plate thicknesses up […]
Orbital welding uses an automatic rotating arc to join objects with little room for user error. Special equipment is needed, including a non-consumable electrode and a power and control system. This technique is popular in cleanroom applications and requires a variety of welding heads to fit different objects. Orbital welding is a method of joining […]
Welding carbon steel to stainless steel is common and often uses MIG welding. Choosing the right grades of steel and welding rods is crucial. MIG welding requires a source of electricity, and the right electrode must be chosen based on location, abrasion, and transfer type. Welding carbon steel to stainless steel is a common process […]
MIG welding is an automatic or semi-automatic process that uses a wire electrode and an inert gas shield to join two pieces of metal. It is faster than traditional welding and can be used with a variety of metals. However, it requires complex equipment and a learning curve for the technique. It is commonly used […]
Dip welding is a process where objects are dipped into molten solder to secure parts together, commonly used in circuit board manufacturing. It can be manual or partially automated and is similar to wave soldering. It is cost-effective for small-scale welding and can be learned through training programs. Inspection is necessary after dip soldering. Dip […]
Fusion welding joins two pieces of metal by melting them with a filler metal and flux. Types include arc, electric resistance, oxy-fuel, thermite, and laser beam welding. Each has unique advantages and limitations. Fusion welding is the process used in metalworking to join or fuse two pieces of metal causing the metal to reach its […]
Stick welding is a manual arc welding process that uses welding sticks made of filler metal and flux to join two pieces of metal together. It is a simple and low-cost method commonly used in pipeline construction, automobile repair, steel building construction, and industrial fabrication. Stick welding is versatile and can be used on various […]
Gas welding uses various gases and oxygen to ignite a torch, melting two materials together. Acetylene is the most common gas used. Skilled operators are needed to ensure a smooth weld, and there are other uses for the oxyfuel torch. Another type of gas welding involves using only one gas without oxygen, which is simpler […]
Gas welding uses gases and oxygen to ignite a torch and combine two materials by heating them until they become molten. Common gases used include acetylene, and a skilled operator is required to ensure a smooth weld. The oxyfuel torch can also be used for cutting metal and other purposes. Another type of gas welding […]
A soldering hammer is used in arc welding to remove slag and clean the weld. In arc welding, a flux-covered welding rod is used to create a weld. The remaining slag must be removed with a welding hammer. Welding hammers come in different styles and sizes, and are important for welding professionals. While not necessary […]
Pipe welding involves joining metal pieces together using different techniques. Certification is often required due to the potential risks involved, and different types of arc welding may be used. Skilled welders understand the importance of tack welding and electrode selection. Pipe welding generally refers to a set of professional skills used for joining pieces of […]
Plastic welding fuses plastic parts together by heating and melting them, creating a chemical bond. Different methods are used based on the equipment, materials, and base plastic. Ultrasonic, vibration, laser, and thermoplastic welding are used for airless welding. Plastic welding is used for repairing expensive parts, creating waterproof containers, and manufacturing products like automotive parts […]
Butt welding joins materials along a single edge in a single plane, commonly used on metal and thermoplastics. A machine applies heat to melt the materials and a filler is added before solidifying. Three types of butt welding are used based on thickness. It is used in various industries and can be performed by machines. […]
Soldering is a process of joining two metal pieces with a special material called solder, which flows over preheated pieces to bond them together. It requires a soldering iron, solder wire, and flux to clean the surfaces. Different metals require different solders and heating methods. Welding joins two pieces of metal, such as electrical wires, […]
Welding joins metals by melting and using filler. It can use gas, electric arc, laser or ultrasound. Modern methods include arc, gas, resistance and energy beam welding. Welding is automated and used in unusual conditions like underwater and in space. Welding is the process of joining metals by melting parts together and then using filler […]
