There are several types of welding processes, 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, also known as Shielded Metal Arc Welding (SMAW), uses a consumable electrode...read more

GMAW is a welding process that uses a continuously fed wire electrode, while SMAW uses a coated electrode.

• GMAW is also known as MIG welding, while SMAW is also known as stick welding.

• GMAW is faster and more efficient than SMAW.

• SMAW is better suited for outdoor welding due to its ability to work in windy conditions.

• GMAW produces less smoke and fumes than SMAW.

• GMAW is better for welding thin materials, while SMAW is bett

The least count of vernier caliper is 0.02 mm and that of micrometer is 0.01 mm.

• Least count is the smallest measurement that can be read on a measuring instrument.

• Vernier caliper has a least count of 0.02 mm, which means it can measure up to 0.02 mm accuracy.

• Micrometer has a least count of 0.01 mm, which means it can measure up to 0.01 mm accuracy.

Welding defects are imperfections that occur during the welding process.

• Porosity: gas pockets in the weld

• Undercutting: groove at the base of the weld

• Incomplete fusion: lack of bonding between the weld and base metal

• Cracks: fractures in the weld or base metal

• Spatter: metal droplets on the surface of the weld

• Distortion: warping or bending of the metal due to heat

• Inclusions: foreign materials in the weld

• Overlap: incomplet

Different types of steel bridges include truss bridges, arch bridges, suspension bridges, and cable-stayed bridges.

• Truss bridges: made of interconnected triangles for support (e.g. Golden Gate Bridge)

• Arch bridges: curved structure supporting weight (e.g. Sydney Harbour Bridge)

• Suspension bridges: main cables supporting the bridge deck (e.g. Akashi Kaikyo Bridge)

• Cable-stayed bridges: cables directly connected to the brid

Different axle capacities in open web bridges vary depending on the design and materials used.

• Axle capacities can range from 10 tons to over 100 tons depending on the bridge design and intended use.

• Common axle capacities for open web bridges include 20 tons, 40 tons, and 80 tons.

• Factors such as bridge span, width, and material strength influence the axle capacity of a bridge.
