There are several types of welding including MIG, TIG, Stick, Flux-Cored, and Submerged Arc Welding.

• MIG (Metal Inert Gas) welding uses a wire electrode and a shielding gas to join two metal pieces together.

• TIG (Tungsten Inert Gas) welding uses a tungsten electrode and a shielding gas to create a precise and clean weld.

• Stick welding uses a consumable electrode coated in flux to create a strong bond between two metal pieces.

• Flux-Cored welding uses a wire electrode with a flux c...read more

GD&T is a system for defining and communicating engineering tolerances. It is applied to ensure parts are manufactured accurately.

• GD&T stands for Geometric Dimensioning and Tolerancing.

• It uses symbols, such as concentricity, perpendicularity, and position, to specify geometric characteristics of parts.

• GD&T helps ensure parts fit together correctly and function properly.

• It is commonly used in industries like automotive, aerospace, and manufacturing.

• By applying GD&T, designers ...read more

GD&T symbols are used to communicate design specifications and tolerances in engineering drawings.

• GD&T stands for Geometric Dimensioning and Tolerancing

• GD&T symbols are used to specify the shape, size, orientation, and location of features on a part

• Tolerance is the allowable variation in a dimension or feature

• GD&T symbols and tolerances ensure that parts are manufactured to the correct specifications and fit together properly

• Examples of GD&T symbols include concentricity, per...read more

Types of fits include clearance, interference, and transition fits.

• Clearance fits have a gap between the mating parts, interference fits have an overlap, and transition fits have both.

• Examples of clearance fits include a loose bolt in a hole, while a press fit is an example of an interference fit.

• Transition fits are used when a balance between clearance and interference is needed, such as in a piston and cylinder assembly.

GD&T stands for Geometric Dimensioning and Tolerancing, a system for defining and communicating engineering tolerances.

• GD&T is a symbolic language used on engineering drawings to specify the allowable variations in form, size, and orientation of features.

• It helps ensure that parts fit together properly and function as intended.

• GD&T uses symbols such as concentricity, flatness, perpendicularity, and position to communicate design requirements.

• It is commonly used in industries ...read more

Torque is the product of force and the perpendicular distance from the axis of rotation to the line of action of the force.

• Torque = Force x Perpendicular distance

• Measured in Newton-meters (Nm) or pound-feet (lb-ft)

• Clockwise torque is negative, counterclockwise torque is positive
