The Complete Welding Terms Glossary

Before starting welding whether it is for home projects or making professional, you should know basic welding glossary to start with. Here are common welding terms Glossary.

Acetone: It is a colourless, unstable and a liquid that is flammable and is used for stabilizing the acetylene that is under pressure.

Alloy: Alloy is the mixture of elements which consists of one metal. Alloy for example can have mild steel and chromium that are used for stainless steel.

Acetylene: It is a colourless hydrocarbon gas that is also called by formula C2H2. This can be used as a useful fuel in oxyacetylene welding.

Alternating Current: This current follows the path if a sine wave and it reverses back and forth. This current can be regarded as an erratic current.

Arc: The arc is used in welding. It can be created to melt the metal as is usually generated between the electrode and the base metal.

Amperage: It van be regarded as the measurement of flow of current. It also tells about the amount of heat that is obtained.

Arc blow: Arc blow is referred to as that condition in which your arc is not in position and is displaced from the original position.

This can be done in DC welding and is due to magnetism.

Arc Cutting: This process is referred to as that process where the metals are being cut.

Arc gouging: In this method the metal can be cut through the arc. The arc here us generated from the carbon electrode.

Arc Voltage: Thus voltage is referred to as that voltage that moves across the arc.

Arc Welding: In this process you can use the electric arc and fuse the metals with each other.

Automatic Welding: These welds are being developed by the creators.

Back pass: This pass is referred to as that pass that lays the back weld.

Back Weld: This can be referred to as the laying of weld on a groove.

Backhand technique: This can be referred to as the push welding. You can also call it pull welding. Here the electrode points are in opposite direction to the direction in which the welding is done.

Backup Strip: This strip can be referred to as that strip where you keep the molten metal and you protect the base metal from the warping.

Bare Metal Arc Welding: This is referred to as that process where the unshielded arc will be producing heat. Thus heat is created between the work piece and the electrode. Here you are producing the filler metal with the electrode.

Base Metal: This can be referred to as the primary piece of metal which is to be melted.

Bead: Bead is referred to as that metal that you can deposit on the base metal when you are welding.

Bevel: This can be referred as angle where the angle is being cut and it allows more filler metal.

Bond: Bond can referred to as that spot or area where a welding metal and the base metal are being connected.

Brazing: Brazing can be referred to as that process in which you melt the filler metal above 800 °F. You can then move it to join it by the capillary action.

Buckling: This can be referred to as the distortion that is being created by the heat.

Butt joint: This can be referred to as that joint where the metal pieces are flat but butted together.

Cap: The cap can be said to be the bead on the groove weld.

Capillary Attraction: In this the liquid metal will be flowing through the narrow joints.

Carbon Arc welds: This type of welding can be done by producing an arc between the base metal and the carob electrode.

Carburizing Flame: This flame is the AKA flame. This can be said to be the oxyacetylene flame that also contains the excess of acetylene.

Coalescence: In this the metals are being fused together.

Coated Electrode: This can be regarded as the welding rod which has flux on the filler metal. The flux can be painted and the arc will be shielded during the burning.

Concavity: Concavity is referred to as that distance where the weld beads protrude from the joint.

Cone: The cone is referred to as that section of tge flame which is near to the tip.

Convexity: Convexity can be referred to as the distance where the weld bead usually protrudes from the joint.

Corner Joint: Corner joint is that joint where you can weld at an angle of 90°.

Crack: Crack is that spot where a fracture arises.

Critical temperature: The temperature at which the base metal will change to liquid from solid.

Current: Current can be said to be the flow of electricity. Current is measured in amps.

Cutting Touch: By using the cutting touch you can control the gases.

Cylinder: Here the various gases are being stored for a number of purposes.

Defect: Defect is referred to as any fault that occurs in a weld. That is porosity or any cracks.

Depth of fusion: This is referred to as the depth at which the filler metal will be penetrating from the metal surface.

Direct current: Direct current is referred to as that situation in which the current will flow continuously from the negative side to the positive side.

Direct Current electrode negative: Here the electricity will be flowing out of the electrode. Due to this reason there is lesser penetration.

Direct Current Electrode positive: here the electricity will be flowing into the electrode. Due to this reason there will be more heat and penetration too.

Ductility: In this situation the metal bends and it becomes deformed.

Duty Cycle: This is referred to as the time in which the welder can operate on a given amperage in a time period of 10 minutes before overheating.

Edge joint: It is a joint where we do butting of two edge pieces at 90°.

Edge Preparation: Here we prepare the edges for the welding purpose. It involves grinding the surface.

Electrode: The arc is developed between the electrode and also the work piece. The electrodes are separate and carry depending on the the type of welding process that is used.

Electrode Holder: It is a clamp which will hold the electrode.

Face: This is the surface of the metal where you will perform the welding.
