Drawing is the process of creating a design or plan, while bending is the process of shaping a material by applying force.

• Drawing involves creating a visual representation of an object or structure, while bending involves physically altering the shape of a material.

• Drawing is typically done on paper or computer software, while bending is done using tools such as a press brake or tube bender.

• Drawing is often used in the...read more

QA is process-oriented and focuses on preventing defects, while QC is product-oriented and focuses on identifying defects.

• QA involves planning, designing, and implementing processes to ensure quality standards are met.

• QC involves testing and inspecting products to identify defects and ensure they meet quality standards.

• QA is proactive, while QC is reactive.

• QA is a preventive measure, while QC is a corrective measure.

• Ex...read more

PPAP (Production Part Approval Process) has 5 stages to ensure quality of parts produced.

• Stage 1: Planning and defining the program

• Stage 2: Product design and development

• Stage 3: Process design and development

• Stage 4: Product and process validation

• Stage 5: Ongoing production, use, and feedback

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

• MIG welding uses a wire electrode and a shielding gas to join two pieces of metal together.

• TIG welding uses a tungsten electrode and a filler metal to create a strong bond between two metals.

• Stick welding uses a consumable electrode coated in flux to create an arc and join two metals together.

• Flux-Cored welding uses a wire electrode w...read more

MIG welding is a process of joining metals using a consumable wire electrode and shielding gas.

• MIG stands for Metal Inert Gas welding

• It is commonly used in automotive and manufacturing industries

• Produces high-quality welds with minimal splatter

• Requires a constant voltage power source and a wire feeder

• Can be used on a variety of metals including steel, aluminum, and stainless steel
