fitting shop

1.What is the purpose of a fitting shop in manufacturing processes?

 Answer: The purpose of a fitting shop is to perform various operations such as cutting, shaping, assembling, and finishing of components to achieve accurate dimensions and fit for final assembly.

2.List some common hand tools used in a fitting shop.

Answer: Some common hand tools used in a fitting shop include wrenches, screwdrivers, pliers, hammers, chisels, files, hacksaws, measuring tools (such as calipers and micrometers), and spanners.

3.Explain the difference between a tap and a die in the context of fitting shop operations.

Answer: A tap is a cutting tool used to create internal threads in a pre-drilled hole, while a die is used to create external threads on cylindrical objects such as bolts or rods. Taps are used for threading holes, whereas dies are used for threading bolts or rods.

4.What safety precautions should be taken when working in a fitting shop?

Answer: Some safety precautions in a fitting shop include wearing appropriate personal protective equipment (PPE) such as safety glasses, gloves, and hearing protection, ensuring proper ventilation, keeping the work area clean and organized, using tools and equipment correctly, and following proper lockout/tagout procedures when working on machinery.

5.Describe the procedure for threading a pipe using a pipe threader in a fitting shop. Answer: The procedure for threading a pipe using a pipe threader typically involves securing the pipe in a pipe vise, applying cutting oil to the pipe and the threader, aligning the threader with the pipe, and rotating the threader to cut the threads into the pipe. The pipe is periodically reversed to break and remove the chips during the threading process.

6.What is the purpose of a reamer, and when is it typically used in a fitting shop?

Answer: A reamer is a cutting tool used to smooth and enlarge holes to achieve precise dimensions and a smooth finish. It is typically used after drilling a hole to remove any rough edges or imperfections and ensure accurate sizing for fitting components or fasteners.

7.How do you measure the size of a bolt or screw in a fitting shop?

Answer: The size of a bolt or screw is typically measured using a caliper or a thread pitch gauge. The caliper is used to measure the major diameter (outer diameter) of the bolt or screw, while the thread pitch gauge is used to determine the pitch or the number of threads per unit of length.

8.Discuss the importance of proper lubrication in fitting shop operations. Answer: Proper lubrication is important in fitting shop operations as it reduces friction, heat, and wear between moving parts. It helps in smooth operation, extends the lifespan of tools and equipment, improves accuracy in machining operations, and prevents damage to components.

9.What are the different types of files used in a fitting shop, and what are their specific applications?

Answer: Different types of files used in a fitting shop include flat files (for general filing and flat surfaces), round files (for enlarging holes or shaping curved surfaces), half-round files (for flat and curved surfaces), and triangular files (for filing corners or angles). Each type of file has specific applications based on the shape of the workpiece and the desired finish.

10.Describe the process of deburring and its significance in a fitting shop.

 Answer: Deburring is the process of removing burrs or sharp edges from machined or cut metal surfaces. It is typically done using files, grinding wheels, or specialized deburring tools. Deburring is significant in a fitting shop as it improves the safety of components, prevents injuries, enhances the fit and finish of assembled parts, and ensures proper functionality.

Job interview questions related to welding shop

Questions related to welding shop

 

Q1: What safety measures should be followed in a welding shop? 

A1: Safety is crucial in a welding shop. Some important measures include wearing appropriate personal protective equipment (PPE) such as welding helmets, gloves, and safety glasses. Ventilation systems should be in place to remove fumes and gases. Fire prevention measures, like having fire extinguishers and keeping the work area free of flammable materials, are also important. Proper training and following established welding procedures are essential for safe operations.

Q2: What types of welding processes are commonly used in a welding shop? 

A2: Several welding processes are commonly used in welding shops. These include:

Shielded Metal Arc Welding (SMAW): Also known as stick welding, it uses a consumable electrode coated in flux.

Gas Metal Arc Welding (GMAW): Also known as MIG (Metal Inert Gas) welding, it uses a continuous wire electrode and a shielding gas.

Gas Tungsten Arc Welding (GTAW): Also known as TIG (Tungsten Inert Gas) welding, it uses a non-consumable tungsten electrode and a shielding gas.

Flux-Cored Arc Welding (FCAW): Similar to GMAW but uses a tubular wire filled with flux.

Submerged Arc Welding (SAW): It uses a continuously fed electrode and a layer of granular flux to shield the arc.

Q3: What are some common welding defects, and how can they be prevented?

A3: Common welding defects include:

Porosity: Caused by gas entrapment, it appears as small holes in the weld. It can be prevented by ensuring proper shielding gas coverage and cleanliness of the base metal.

Weld cracking: Occurs due to stress or improper cooling. Proper preheating, controlling welding parameters, and post-weld heat treatment can help prevent cracking.

Incomplete fusion: Happens when the weld metal does not fuse properly with the base metal. It can be avoided by ensuring proper joint preparation and welding technique.

Undercutting: A groove formed at the base of the weld due to excessive heat. Proper control of the welding current and speed can prevent undercutting.

Q4: How should welding equipment be maintained in a welding shop?

 A4: Regular maintenance of welding equipment is important for optimal performance and safety. Some key maintenance practices include:

Cleaning and inspecting welding machines and cables regularly to ensure they are free from dirt, debris, and damage.

A5: The qualifications and certifications required may vary depending on the location and specific job requirements.

Q6: What are some common causes of weld distortion, and how can it be minimized?

A6: Weld distortion can occur due to factors such as uneven heating and cooling, excessive weld metal, or improper joint fit-up. To minimize distortion, it is important to use proper welding techniques, control heat input, use fixtures or jigs to hold the workpiece in position during welding, and implement preheating or post-weld heat treatment if necessary.

Q7: What are the different types of welding positions?

A7: Welding positions define the orientation of the joint relative to the welder. Common welding positions include flat position (1G), horizontal position (2G), vertical position (3G and 4G), and overhead position (4G and 6G). Each position may require specific techniques and considerations to achieve quality welds.

Q8: What is the purpose of a welding procedure specification (WPS)?
