Match the following welding processes with their descriptions:

Arc welding = Uses electricity to create an arc between the base material and an electrode MIG welding = Uses a wire electrode and a shielding gas to join metals TIG welding = Uses a non-consumable tungsten electrode and a shielding gas to create a weld Spot welding = Joins two or more metal sheets together by applying pressure and heat at localized points Signup and view all the answers

Match the following mechanical properties with their definitions:

Tensile strength = Maximum stress a material can withstand while being stretched or pulled before necking or fracture occurs Yield strength = Stress at which a material begins to deform plastically Elongation = Measure of the ductility of a material, expressed as a percentage increase in length Modulus of elasticity = Measure of a material's stiffness or resistance to deformation in the elastic range Signup and view all the answers

Match the following welding joint types with their descriptions:

Butt joint = Where two pieces of metal are joined by aligning them in the same plane Fillet joint = A triangular cross-section of weld metal that joins two surfaces at right angles to each other Lap joint = Where two overlapping pieces are joined together along their edges T-joint = Formed when the edge or end of one member is butted against the face or edge of the other Signup and view all the answers
