A Brief Introduction to MIG Welding

When you think of welding, MIG welding is probably what comes to mind.  MIG stands for metal inert gas.  It’s also referred to GMAW or gas metal arc welding.  It consists of a spool of wire that is fed, along with an inert gas, through

Welding In Space, The Final Frontier

   Steven Hawking, renowned British astrophysicist warns the planet Earth is quickly running out of resources, and in order for mankind to survive beyond the next century, our only hope is outer space.    Welding was first performed in space 25 years ago by Russian

Welding Plastics

Plastics Plastic is cheaper, lighter, more corrosion resistant, easier to cut and shape and drill, has a very low thermal conductivity, and a higher strength to weight ratio than metals. Cars, clothes, food containers, and toys are all items that have been revolutionized by the

An Introduction to TIG Welding

TIG welding, or tungsten inert gas welding, also known as GTAW (gas tungsten arc welding), is one of my personal favorites.  It consists of a piece of tungsten (the electrode), used to conduct electricity to the work, held in a “torch”, with an inert gas

Specialty Welding Processes

Explosive Welding Explosive welding is a solid state welding process, that uses a controlled explosive detonation to usually fuse two dissimilar metals together at high pressure. The result is a composite durable, metallurgical bond. Explosive welding under high velocity impact was first recognized in 1944.

Overview of Orbital Welding

The orbital welding process gets its name from the fact that an electrode rotates around, or “orbits,” the stationary product being welded. As with tungsten inert gas (TIG) welding, an electric arc is produced between a non-consumable tungsten electrode and the metal that is welded.

About Plasma Cutting

Plasma cutting is the process that is used to cut steel and other metals of different thicknesses using a plasma torch. An inert gas or compressed air is blown at high speed out of a nozzle and at the same time an electric arc is

Welding Schools: What is out there?

Community colleges, technical and trade schools, and universities There are many different types of welding schools.  Depending upon the level of certification a student wants to achieve, or how much time and money is available, there are plenty of options. Many students begin to learn

Specialized Welding Jobs

Industrial Hot Tapping    Hot tapping allows work to be performed on an existing live piping system without the need for venting or shutting down operations, and is only performed when it is not feasible, or is impractical, to take the equipment or piping system

Plastic Welding – How to Weld Plastic

Most people when they think of welding will think of heat, bright light, sparks, molten metal, and a guy in a mask, or perhaps a robotic arm.  But welding doesn’t only apply to metals.  Believe it or not, some plastics can be welded as well.
