Welding Methods Explained
MIG Welding
Metal Inert Gas (MIG) welding is one of the most versatile processes used to join metals. MIG welding incorporates a shielding gas with a solid electrode wire that is continuously fed into a hand-held MIG torch. The heat produced from an electric arc melts the wire onto the base material, creating a weld pool that fuses them together. Both skilled welders and robotic welding machines perform a variety of MIG welds on steel or stainless steel. This welding method is preferable for thicker material and for fill passes in thick-wall pipe welds.
TIG Welding
TIG or Tungsten Inert Gas welding is ideal for specific penetration on thinner materials requiring precision welds. This welding method incorporates a tungsten electrode arc from the welding torch with a separate metal filler rod. A small, intense arc heats the base metal until it melts, then the filler rod is dipped into the melted pool, and the two pieces begin to join. TIG welding arcs produce less spatter than MIG arcs, offering a good amount of control for the user and a cleaner finish.
Stick Welding
The stick welding method is one of the simplest and most cost-efficient processes of joining materials. A flux-coated rod and the metal workpieces are melted together at one point to form a weld pool. As the pool cools, the joint between the two metals forms a sturdy bond. No shielding gas is needed in this process, which is widely used on steel, aluminum, nickel, and copper alloys. Stick welding tends to create molten splatter, and finished products require more cleaning and sanding than other arc welding methods.
Stud Welding
Stud welding joins a fastener to a metal object or surface by way of an electric arc. As the fastener heats up and the surface area melts, the fastener is manipulated into position, and the weld is formed. There are two types of stud welding: drawn arc and capacitor discharge. Drawn arc welding requires both the fastener and the base material to be heated. Capacitor discharge creates some of the fastest stud welds, using a stud gun to trigger the weld charge and melt the fastener head to the base material simultaneously.
Laser Welding
Laser welding generates a highly concentrated beam of light to produce a metal-to-metal weld with no filler material needed. The beam of light is amplified and directed onto the material seams until they reach a melting point, which fuses the two surfaces together. Gas, solid-state, and fiber are the most common types of laser welding technologies. Each produces a cleaner edge with improved perpendicularity than other forms of flame cutting. The laser welding process is excellent for cutting carbon steel, low alloy steel, aluminum, and stainless-steel material from light gauge to heavier gauge thickness and plate.
Projection Welding
Projection welding is a form of resistance welding that uses pressure and an electrical current to join metal parts. Projections or dimples are manufactured on the base material. As parts are brought together, an electrical current is focused on the projection points, generating heat through an electric pulse in these specific locations. Force is applied from upper and lower plateaus connecting the parts together as the current is applied. Projection welding is commonly used to weld connectors such as bolts, nuts, and screws to base metal parts.
Resistance Spot Welding
Spot welding utilizes a pair of water-cooled copper electrodes to clamp two workpieces together and pass an electric current between them. The electrical resistance of the part material generates enough heat to form a weld nugget that bonds the pieces together. This type of welding is used to manufacture pipe, tubing, and smaller structural sections, and is popular in the automotive industry as well as in other manufacturing products made of thinner gauge materials.
