Ganesh Electricals Interview Questions and Answers

Welding defects are imperfections that occur during the welding process. Common defects include porosity, cracks, and incomplete fusion.

• Porosity: caused by gas entrapment in the weld pool, can be prevented by proper shielding gas and electrode selection

• Cracks: caused by excessive stress or improper cooling, can be prevented by controlling heat input and using preheat/ post-weld heat treatment

• Incomplete fusion: caused by insufficient heat or improper technique, can be prevente...read more

Bar chart displays categorical data while histogram displays continuous data.

• Bar chart has discrete categories on x-axis while histogram has continuous range of values.

• Bar chart is used to compare different categories while histogram is used to show distribution of data.

• Bar chart has gaps between bars while histogram has no gaps.

• Example of bar chart: Number of students in each grade level. Example of histogram: Distribution of heights in a population.

Pareto principle is an economic theory that states 80% of the effects come from 20% of the causes.

• Also known as the 80/20 rule

• Named after Italian economist Vilfredo Pareto

• Applied in various fields such as business, economics, and quality control

• Example: 80% of a company's profits come from 20% of its customers

Production is the process of creating goods or services using resources like labor, machinery, and materials.

• Production can be classified into three main types: job production, batch production, and mass production.

• Job production involves producing custom-made products one at a time, such as tailor-made clothing.

• Batch production involves producing a specific quantity of identical products at a time, such as baking a batch of cookies.

• Mass production involves producing large qu...read more

Types of welding include MIG, TIG, stick, and flux-cored. Measurement instruments include calipers, micrometers, and rulers.

• Types of welding: MIG, TIG, stick, flux-cored

• Measurement instruments: calipers, micrometers, rulers

Core tools of IATF include PPAP, SPC, MSA, FMEA, APQP, 7QC tools, 8D.

• PPAP (Production Part Approval Process) ensures that all customer requirements are understood and met.

• SPC (Statistical Process Control) monitors and controls the quality of a process.

• MSA (Measurement System Analysis) evaluates the measurement system's ability to provide accurate and reliable data.

• FMEA (Failure Mode and Effects Analysis) identifies potential failures and their impact on the product or process...read more

A control plan is a document that outlines the steps to be taken to ensure quality standards are met during production.

• It is a proactive approach to quality control

• It identifies potential issues and outlines steps to prevent them

• It includes details on inspection and testing procedures

• It helps ensure consistency in product quality

• Examples include process flow diagrams, FMEA, and control charts
