IMP LAB

RAT TAIL OR PIG TAIL

• This kind of joint is commonly used to join two or more conductors inside the junction box.

• It is suitable for service where there is no mechanical stress when wires are to be connected in an outlet box, switch, or conduit fitting

Y - SPLICE

• This method of wrapping is generally used on small cables because the strands are flexible and all can be wrapped in one operation.

KNOTTED TAP

• This is used where the tap wire is under heavy tensile stress

PLAIN TAP JOINT

• This is used where the tap wire is under considerable tensile stress circuit.

AERIAL TAP

• used as a temporary tap usually done in constructions sites. The easy twist will facilitate tap wire movement

DUPLEX CROSS JOINT

• This is a two-tap wire turned simultaneously and is used where the two tap wire is under heavy tensile stress

WESTERN UNION SHORT - TIE SPLICE

• most widely used splice or joint in interior wiring installation to extend the length of wire from one point to another.

WESTERN UNION LONG - TIE SPLICE

• used extensively for outside wiring to extend the length of wire from one end to another.

CROSS JOINT

same application is done as in plain tap and the only difference is that this tap is a combination of two plain taps place side by side with each other.

WRAPPED TAP OR TEE JOINT

• used on large solid conductors where it is difficult to wrap the heavy tap wire around the main wire.

EXTENSION CORD

•  span of flexible electrical power cable with a plug on one end and multiple sockets on the other end.

WORKSHOP TOOLS

• cover a wide range of equipment and devices used for various tasks, repairs, constructions, or creations in a workshop setting. They can be classified into several categories based on their functions and purposes.

Brushes, Rollers

Used for applying paints, varnishes, or coatings to surfaces.

Welders, Soldering Irons

Essential for metalworking, joining or repairing metal components.

Lathes, Planers, Jointers (Woodworking Machinery)

Used for shaping and refining wood in various ways.

Air Compressors and Pneumatic Tools

Powered by compressed air, these tools include nail guns, spray guns, and impact wrenches, among others.

Safety Glasses, Gloves

Essential for protecting eyes and hands from potential hazards.

Ear Protection, Respirators

Used in environments with high noise levels or airborne particles.

WELDING

fabrication process that joins materials, usually metals or thermoplastics, by causing fusion.

Shielded Metal Arc Welding

Uses a consumable electrode coated in flux to generate an arc between the electrode and the workpiece, creating a weld pool. The flux shields the weld from atmospheric contamination.

Gas Metal Arc Welding

Involves a continuous solid wire electrode fed through a welding gun, along with a shielding gas to protect the weld pool from atmospheric contamination.

Flux-Cored Arc Welding

Similar to GMAW but uses a tubular wire filled with flux, eliminating the need for a shielding gas.

Gas Tungsten Arc Welding

Uses a non-consumable tungsten electrode to produce the weld and typically requires a separate filler material. Often used for high-quality welds in thin materials.

Spot Welding

Joins overlapping metal surfaces by applying pressure and heat to a small area. Commonly used in automotive manufacturing.

Seam Welding

Similar to spot welding but creates a continuous weld along a seam by continuously rolling the electrodes.

Oxy-Acetylene Welding

Utilizes a combination of oxygen and acetylene gas to create a high- temperature flame for welding metals.

Friction Welding

Involves rubbing two materials together at high speeds, generating heat due to friction and forming a weld once the materials are sufficiently heated.

Ultrasonic Welding

Uses high-frequency ultrasonic vibrations to create frictional heat, welding plastics or metals together.

Arc Welding Machine

Generates an electrical current that creates an arc between the electrode and the workpiece. Different types include stick welders, MIG welders, TIG welders, etc.

Welding Helmet

Shields the face and eyes from sparks, intense light, and debris during welding.

Welding Gloves

Insulated gloves that protect hands from heat, sparks, and potential burns.

Welding Jacket or Apron

Protects the torso and arms from heat, sparks, and UV radiation.

Welding Boots

Heat-resistant footwear to protect feet and ankles from sparks and heat.

Electrodes

Consumable rods used in arc welding that conduct the electric current and create the arc.

Welding Wires:

Used in MIG and flux-cored welding processes as a continuous feed wire to create the weld.

Filler Metals

Additional materials used to reinforce the weld or join two pieces of metal.

Welding Clamps

Used to hold metal pieces together in the desired position while welding.

Magnetic Welding Holders

Assist in positioning metal pieces by providing magnetic support.

Regulators and Hoses

Control the flow of gases in gas welding processes.

Welding Torch

Used in gas welding processes like oxy-acetylene welding for providing the flame.
